is Metabolic phospholipid labeling of intact bacteria enables a fluorescence assay that detects compromised outer membranes [Research Articles] By feedproxy.google.com Published On :: 2020-03-10T09:30:25-07:00 Gram-negative bacteria possess an asymmetric outer membrane (OM) composed primarily of lipopolysaccharides (LPS) on the outer leaflet and phospholipids (PLs) on the inner leaflet. Loss of this asymmetry due to mutations in the lipopolysaccharide (LPS) biosynthesis or transport pathways causes externalization of PLs to the outer leaflet of the OM and leads to OM permeability defects. Here, we employed metabolic labeling to detect a compromised OM in intact bacteria. Phosphatidylcholine synthase (Pcs) expression in Escherichia coli allowed for incorporation of exogenous propargylcholine (PCho) into phosphatidyl(propargyl)choline (PPC) and for incorporation of exogenous 1-azidoethyl-choline (AECho) into phosphatidyl(azidoethyl)choline (AEPC) as confirmed by LC-MS analyses. A fluorescent copper-free click reagent poorly labeled AEPC in intact wild-type cells, but readily labeled AEPC from lysed cells. Fluorescence microscopy and flow cytometry analyses confirmed the absence of significant AEPC labeling from intact wild-type E. coli strains, and revealed significant AEPC labeling in an E. coli LPS transport mutant (lptD4213) and an LPS biosynthesis mutant (E. coli lpxC101). Our results suggest that metabolic PL labeling with AECho is a promising tool to detect a compromised bacterial OM, reveal aberrant PL externalization, and identify or characterize novel cell-active inhibitors of LPS biosynthesis or transport.

is Serum non-esterified fatty acids have utility as dietary biomarkers of fat intake from fish, fish oil and dairy in women [Methods] By feedproxy.google.com Published On :: 2020-03-31T09:30:24-07:00 Nutritional studies rely on various biological specimens for fatty acid (FA) determination, yet it is unclear how levels of serum non-esterified FA (NEFAs) correlate with other circulating lipid pools. Here, we used a high throughput method (< 4 min/sample) based on multisegment injection-non-aqueous-capillary electrophoresis–mass spectrometry (MSI-NACE-MS) to investigate whether specific serum NEFAs have utility as biomarkers of dietary fat intake in women. We first identified circulating NEFAs correlated with long-term/habitual food intake among pregnant women with contrasting dietary patterns (n=50). Acute changes in serum NEFA trajectories were also studied in non-pregnant women (n=18) following high-dose (5 g/day) fish oil (FO) supplementation or isoenergetic sunflower oil placebo over 56 days. In the cross-sectional study, serum omega-3 (-3) FA correlated with self-reported total -3 daily intake, notably eicosapentaenoic acid (EPA) as its NEFA (r=0.46; p=0.001), whereas pentadecanoic acid was associated with full-fat dairy intake (r=0.43; p=0.002), outcomes consistent with results from total FA serum hydrolysates. In the intervention cohort, serum -3 NEFAs increased 2.5-fold from baseline within 28 days following FO supplementation, and this increase was most pronounced for EPA (p=0.0004). Unlike for docosahexaenoic acid, circulating EPA as its NEFA also strongly correlated to EPA concentrations measured from erythrocyte phospholipid hydrolysates (r=0.66; p=4.6 x 10-10), and was better suited to detect dietary non-adherence. We conclude that MSI-NACE-MS offers a rapid method to quantify serum NEFAs and objectively monitor dietary fat intake in women that is complementary to diet records or food frequency questionnaires.

is Roles of endogenous ether lipids and associated PUFA in the regulation of ion channels and their relevance for disease [Research Articles] By feedproxy.google.com Published On :: 2020-04-07T06:36:30-07:00 Ether lipids (ELs) are lipids characterized by the presence of either an ether linkage (alkyl lipids) or a vinyl ether linkage (i.e. plasmalogens [Pls]) at the sn1 position of the glycerol backbone and they are enriched in PUFAs at the sn2 position. In this review, we highlight that ELs have various biological functions, act as a reservoir for second messengers (such as PUFAs), and have roles in many diseases. Some of the biological effects of ELs may be associated with their ability to regulate ion channels that control excitation-contraction/secretion/mobility coupling and therefore cell physiology. These channels are embedded in lipid membranes, and lipids can regulate their activities directly or indirectly as second messengers or by incorporating into membranes. Interestingly, ELs and EL-derived PUFAs have been reported to play a key role in several pathologies, including neurological disorders, cardiovascular diseases, and cancers. Investigations leading to a better understanding of their mechanisms of action in pathologies have opened a new field in cancer research. In summary, newly identified lipid regulators of ion channels, such as ELs and PUFAs, may represent valuable targets to improve disease diagnosis and advance the development of new therapeutic strategies for managing a range of diseases and conditions.

is Skin barrier lipid enzyme activity in Netherton patients is associated with protease activity and ceramide abnormalities [Research Articles] By feedproxy.google.com Published On :: 2020-04-07T14:33:32-07:00 Individuals with Netherton syndrome (NTS) have increased serine protease activity, which strongly impacts the barrier function of the skin epidermis and leads to skin inflammation. Here, we investigated how serine protease activity in NTS correlates with changes in the stratum corneum ceramides, which are crucial components of the skin barrier. We examined two key enzymes involved in epidermal ceramide biosynthesis, glucocerebrosidase (GBA) and acid-sphingomyelinase (ASM). We compared in situ expression levels and activities of GBA and ASM between NTS patients and controls and correlated the expression and activities with i) stratum corneum ceramide profiles, ii) in situ serine protease activity, and iii) clinical presentation of patients. Using activity-based probe labeling, we visualized and localized active, epidermal GBA, and a newly developed in situ zymography method enabled us to visualize and localize active ASM. Reduction in active GBA in NTS patients coincided with increased ASM activity, particularly in areas with increased serine protease activity. NTS patients with scaly erythroderma exhibited more pronounced anomalies in GBA and ASM activities than patients with ichthyosis linearis circumflexa. They also displayed a stronger increase in stratum corneum ceramides processed via ASM. We conclude that changes in the localization of active GBA and ASM correlate with i) altered stratum corneum ceramide composition in NTS patients, ii) local serine protease activity, and iii) the clinical manifestation of NTS.

is Circulating oxidized LDL increased in patients with acute myocardial infarction is accompanied by heavily modified HDL. [Research Articles] By feedproxy.google.com Published On :: 2020-04-14T05:33:23-07:00 Oxidized low-density lipoprotein (oxLDL) is a known risk factor for atherogenesis. This study aimed to reveal structural features of oxLDL present in human circulation related to atherosclerosis. When LDL was fractionated on an anion-exchange column, in vivo-oxLDL, detected by the anti-oxidized phosphatidylcholine (oxPC) monoclonal antibody, was recovered in flow-through and electronegative LDL (LDL(-)) fractions. The amount of the electronegative in vivo-oxLDL, namely oxLDL in LDL(-) fraction, present in patients with acute myocardial infarction (AMI) was three-fold higher than that observed in healthy subjects. Surprisingly, LDL(-) fraction contained apoA1 in addition to apoB, and HDL-sized particles were observed with transmission electron microscopy. In LDL(-) fractions, acrolein adducts were identified at all lysine residues in apoA1, with only a small number of acrolein-modified residues were identified in apoB. The amount of oxPC adducts of apoB was higher in LDL(-) than in L1 fraction as determined using western blotting. The electronegative in vivo-oxLDL was immunologically purified from the LDL(-) fraction with an anti-oxPC monoclonal antibody. Majority of PC species was not oxidized, whereas oxPC and lysoPC did not accumulate. Here, we propose that there are two types of in vivo-oxLDL in human circulating plasma and the electronegative in vivo-oxLDL accompanies oxidized HDL. Full Article
is Dietary plant stanol ester supplementation reduces peripheral symptoms in a mouse model of Niemann-Pick type C1 disease. [Research Articles] By feedproxy.google.com Published On :: 2020-04-14T06:30:26-07:00 Niemann–Pick type C1 (NPC1) disease is a rare genetic condition in which the function of the lysosomal cholesterol transporter NPC1 protein is impaired. Consequently, sphingolipids and cholesterol accumulate in lysosomes of all tissues, triggering a cascade of pathological events that culminate in severe systemic and neurological symptoms. Lysosomal cholesterol accumulation is also a key-factor in the development of atherosclerosis and non-alcoholic steatohepatitis (NASH). In these two metabolic diseases, the administration of plant stanol esters has been shown to ameliorate cellular cholesterol accumulation and inflammation. Given the overlap of pathological mechanisms among atherosclerosis, NASH and NPC1 disease, we sought to investigate whether dietary supplementation with plant stanol esters improves the peripheral features of NPC1 disease. To this end, we used an NPC1 murine model featuring an Npc1 null allele (Npc1nih), creating a dysfunctional NPC1 protein. Npc1nih mice were fed a two or six percent plant stanol esters–enriched diet over the course of 5 weeks. During this period, hepatic and blood lipid and inflammatory profiles were assessed. Npc1nih mice fed the plant stanol–enriched diet exhibited lower hepatic cholesterol accumulation, damage and inflammation than regular chow–fed Npc1nih mice. Moreover, plant stanol consumption shifted circulating T-cells and monocytes in particular towards an anti-inflammatory profile. Overall, these effects were stronger following dietary supplementation with 6% stanols, suggesting a dose-dependent effect. The findings of our study highlight the potential use of plant stanols as an affordable complementary means to ameliorate disorders in hepatic and blood lipid metabolism and reduce inflammation in NPC1 disease.

is A simple method for sphingolipid analysis of tissues embedded in optimal cutting temperature compound [Methods] By feedproxy.google.com Published On :: 2020-04-27T14:30:22-07:00 Mass spectrometry (MS) assisted lipidomic tissue analysis is a valuable tool to assess sphingolipid metabolism dysfunction in disease. These analyses can reveal potential pharmacological targets or direct mechanistic studies to better understand the molecular underpinnings and influence of sphingolipid metabolism alterations on disease etiology. But procuring sufficient human tissues for adequately powered studies can be challenging. Therefore, biorepositories, which hold large collections of cryopreserved human tissues, are an ideal retrospective source of specimens. However, this resource has been vastly underutilized by lipid biologists, as the components of optimal cutting temperature compound (OCT) used in cryopreservation are incompatible with MS analyses. Here, we report results indicating that OCT also interferes with protein quantification assays, and that the presence of OCT impacts the quantification of extracted sphingolipids by LC–ESI–MS/MS. We developed and validated a simple and inexpensive method that removes OCT from OCT-embedded tissues. Our results indicate that removal of OCT from cryopreserved tissues does not significantly affect the accuracy of sphingolipid measurements with LC–ESI–MS/MS. We used the validated method to analyze sphingolipid alterations in tumors compared with normal adjacent uninvolved lung tissues from individuals with lung cancer, and to determine the long-term stability of sphingolipids in OCT-cryopreserved normal lung tissues. We show that lung cancer tumors have significantly altered sphingolipid profiles and that sphingolipids are stable for up to 16 years in OCT-cryopreserved normal lung tissues. This validated sphingolipidomic OCT-removal protocol should be a valuable addition to the lipid biologist’s toolbox. Full Article

is Metabolic regulation of the lysosomal cofactor bis(monoacylglycero)phosphate in mice [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T07:33:43-07:00 Bis(monoacylglycero)phosphate (BMP), also known as lysobisphosphatidic acid (LBPA), is a phospholipid that promotes lipid sorting in late endosomes/lysosomes by activating lipid hydrolases and lipid transfer proteins. Changes in the cellular BMP content therefore reflect an altered metabolic activity of the endo-lysosomal system. Surprisingly, little is known about the physiological regulation of BMP. In this study, we investigated the effects of nutritional and metabolic factors on BMP profiles of whole tissues and parenchymal and non-parenchymal cells. Tissue samples were obtained from fed, fasted, two-hours refed, and insulin-treated mice, as well as from mice housed at 5°C, 22°C, or 30°C. These tissues exhibited distinct BMP profiles, which were regulated by the nutritional state in a tissue-specific manner. Insulin treatment was not sufficient to mimic refeeding-induced changes in tissue BMP levels indicating that BMP metabolism is regulated by other hormonal or nutritional factors. Tissue fractionation experiments revealed that fasting drastically elevates BMP levels in hepatocytes and pancreatic cells. Furthermore, we observed that the BMP content in brown adipose tissue strongly depends on housing temperatures. In conclusion, our observations suggest that BMP concentrations adapt to the metabolic state in a tissue-and cell type-specific manner in mice. Drastic changes observed in hepatocytes, pancreatic cells, and brown adipocytes suggest that BMP possesses a role in the functional adaption to nutrient starvation and ambient temperature.

is Parenteral lipids shape gut bile acid pools and microbiota profiles in the prevention of cholestasis in preterm pigs [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T08:36:37-07:00 Multi-component lipid emulsions, rather than soy-oil emulsions, prevent cholestasis by an unknown mechanism. Here, we quantified liver function, bile acid pools, and gut microbial and metabolite profiles in premature, parenterally fed pigs given a soy-oil lipid emulsion, Intralipid (IL); a multi component lipid emulsion, SMOFlipid (SMOF); a novel emulsion with a modified fatty-acid composition (EXP); or a control enteral diet (ENT) for 22 days. We assayed serum cholestasis markers; measured total bile acid levels in plasma, liver, and gut contents; and analyzed colonic bacterial 16S rRNA gene sequences and metabolomic profiles. Serum cholestasis markers (i.e. bilirubin, bile acids, and g-glutamyl transferase) were highest in IL-fed pigs and normalized in those given SMOF, EXP, or ENT. Gut bile acid pools were lowest in the IL treatment and were increased in the SMOF and EXP treatments and comparable to ENT. Multiple bile acids, especially their conjugated forms, were higher in the colon contents of SMOF and EXP than in IL pigs. Colonic microbial communities of SMOF and EXP pigs had lower relative abundance of several Gram-positive anaerobes, including Clostridrium XIVa, and higher abundance of Enterobacteriaceae than those of IL and ENT pigs. Differences in lipid and microbial-derived compounds were also observed in colon metabolite profiles. These results indicate that multi-component lipid emulsions prevent cholestasis and restore enterohepatic bile flow in association with gut microbial and metabolomic changes. We conclude that sustained bile flow induced by multi-component lipid emulsions likely exerts a dominant effect in reducing bile acid–sensitive, Gram-positive bacteria. Full Article
is Sphingolipids distribution at mitochondria-associated membranes (MAM) upon induction of apoptosis. [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T08:36:37-07:00 The levels and composition of sphingolipids and related metabolites are altered in aging and common disorders such as diabetes and cancers, as well as in neurodegenerative, cardiovascular, and respiratory diseases. Changes in sphingolipids have been implicated as being an essential step in mitochondria-driven cell death. However, little is known about the precise sphingolipid composition and modulation in mitochondria or related organelles. Here, we used LC–MS/MS to analyze the presence of key components of the ceramide metabolic pathway in vivo and in vitro in purified endoplasmic reticulum (ER), mitochondria-associated membranes (MAM), and mitochondria. Specifically, we analyzed the sphingolipids in the three pathways that generate ceramide: sphinganine in the de novo ceramide pathway, sphingomyelin in the breakdown pathway, and sphingosine in the salvage pathway. We observed sphingolipid profiles in mouse liver, mouse brain, and a human glioma cell line (U251). We analyzed the quantitative and qualitative changes of these sphingolipids during staurosporine (STS)-induced apoptosis in U251 cells. Ceramide, especially C16-ceramide, levels increased during early apoptosis possibly through a conversion from mitochondrial sphinganine and sphingomyelin, but sphingosine and lactosyl- and glucosyl-ceramide levels were unaffected. We also found that ceramide generation is enhanced in mitochondria when sphingomyelin levels are decreased in the MAM. This decrease was associated with an increase in acid sphingomyelinase (ASM) activity in MAM. We conclude that meaningful sphingolipid modifications occur in MAM, the mitochondria, and ER during the early phases of apoptosis. Full Article
is Bisretinoid phospholipid and vitamin A aldehyde: Shining a light [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-05T13:30:26-07:00 Vitamin A aldehyde covalently bound to opsin protein is embedded in a phospholipid-rich membrane that supports photon absorption and phototransduction in photoreceptor cell outer segments. Following absorption of a photon, the 11-cis-retinal chromophore of visual pigment in photoreceptor cells isomerizes to all-trans-retinal. To maintain photosensitivity 11-cis-retinal must be replaced. At the same time, however, all-trans-retinal has to be handled so as to prevent nonspecific aldehyde activity. Some molecules of retinaldehyde upon release from opsin are efficiently reduced to retinol. Other molecules are released into the lipid phase of the disc membrane where they form a conjugate (N-retinylidene-PE, NRPE) through a Schiff base linkage with phosphatidylethanolamine (PE). The reversible formation of NRPE serves as a transient sink for retinaldehyde that is intended to return retinaldehyde to the visual cycle. However, if instead of hydrolyzing to PE and retinaldehyde, NRPE reacts with a second molecule of retinaldehyde a synthetic pathway is initiated that leads to the formation of multiple species of unwanted bisretinoid fluorophores. We report on recently identified members of the bisretinoid family some of which differ with respect to the acyl chains associated with the glycerol backbone. We discuss processing of the lipid moieties of these fluorophores in lysosomes of retinal pigment epithelial (RPE) cells, their fluorescence characters and new findings related to light and iron-associated oxidation of bisretinoids.

is 2-Chlorofatty acids are biomarkers of sepsis mortality and mediators of barrier dysfunction in rats [Research Articles] By feedproxy.google.com Published On :: 2020-05-06T11:30:34-07:00 Sepsis is defined as the systemic, dysregulated host immune response to an infection that leads to injury to host organ systems, and, often, death. Complex interactions between pathogens and their hosts elicit microcirculatory dysfunction. Neutrophil myeloperoxidase (MPO) is critical for combating pathogens, but MPO-derived hypochlorous acid (HOCl) can react with host molecular species as well. Plasmalogens are targeted by HOCl, leading to the production of 2-chlorofatty acids (2-CLFAs). 2-CLFAs are associated with human sepsis mortality, decrease in vitroendothelial barrier function, and activate human neutrophil extracellular trap formation. Here, we sought to examine 2-CLFAs in an in vivorat sepsis model. Intraperitoneal cecal slurry sepsis with clinically relevant rescue therapies led to ~73% mortality and evidence of microcirculatory dysfunction. Plasma concentrations of 2-CLFAs assessed 8h after sepsis induction were lower in rats that survived sepsis than in non-survivors. 2-CLFA levels were elevated in kidney, liver, spleen, lung, colon and ileum in septic animals. In vivo, exogenous 2-CLFA treatments increased kidney permeability, and in in vitroexperiments 2-CLFA also increased epithelial surface expression of vascular cell adhesion molecule 1 and decreased epithelial barrier function. Collectively, these studies support a role of free 2-CLFAs as biomarkers of sepsis mortality, potentially mediated, in part, by 2-CLFA-elicited endothelial and epithelial barrier dysfunction.

is America's Coronavirus Response Is Shaped By Its Federal Structure By feedproxy.google.com Published On :: Mon, 16 Mar 2020 09:00:36 +0000 16 March 2020 Dr Leslie Vinjamuri Dean, Queen Elizabeth II Academy for Leadership in International Affairs; Director, US and the Americas Programme @londonvinjamuri Google Scholar The apparent capacity of centralized state authority to respond effectively and rapidly is making headlines. In the United States, the opposite has been true. 2020-03-16-Coronavirus-America.jpg Harvard asked its students to move out of their dorms due to the coronavirus risk, with all classes moving online. Photo by Maddie Meyer/Getty Images. As coronavirus spreads across the globe, states grapple to find the ideal strategy for coping with the global pandemic. And, in China, Singapore, South Korea, the US, the UK, and Europe, divergent policies are a product of state capacity and legal authority, but they also reveal competing views about the optimal role of centralized state authority, federalism, and the private sector.Although it is too soon to know the longer-term effects, the apparent capacity of centralized state authority in China, South Korea and Singapore to respond effectively and rapidly is making headlines. In the United States, the opposite has been true. America’s response is being shaped by its federal structure, a dynamic private sector, and a culture of civic engagement. In the three weeks since the first US case of coronavirus was confirmed, state leaders, public health institutions, corporations, universities and churches have been at the vanguard of the nation’s effort to mitigate its spread.Images of safety workers in hazmat suits disinfecting offices of multinational corporations and university campuses populate American Facebook pages. The contrast to the White House effort to manage the message, downplay, then rapidly escalate its estimation of the crisis is stark.Bewildering responseFor European onlookers, the absence of a clear and focused response from the White House is bewildering. By the time President Donald Trump declared a national emergency, several state emergencies had already been called, universities had shifted to online learning, and churches had begun to close.By contrast, in Italy, France, Spain and Germany, the state has led national efforts to shutter borders and schools. In the UK, schools are largely remaining open as Prime Minister Boris Johnson has declared a strategy defined by herd immunity, which hinges on exposing resilient populations to the virus.But America has never shared Europe’s conviction that the state must lead. The Center for Disease Control and Prevention, the leading national public health institute and a US federal agency, has attempted to set a benchmark for assessing the crisis and advising the nation. But in this instance, its response has been slowed due to faults in the initial tests it attempted to rollout. The Federal Reserve has moved early to cut interest rates and cut them again even further this week.But states were the real first movers in America’s response and have been using their authority to declare a state of emergency independent of the declaration of a national emergency. This has allowed states to mobilize critical resources, and to pressure cities into action. After several days delay and intense public pressure, New York Governor Andrew Cuomo forced New York City Mayor Bill de Blasio to close the city’s schools.Declarations of state emergencies by individual states have given corporations, universities and churches the freedom and legitimacy to move rapidly, and ahead of the federal government, to halt the spread in their communities.Washington state was the first to declare a state of emergency. Amazon, one of the state’s leading employers, quickly announced a halt to all international travel and, alongside Microsoft, donated $1million to a rapid-response Seattle-based emergency funds. States have nudged their corporations to be first movers in the sector’s coronavirus response. But corporations have willingly taken up the challenge, often getting ahead of state as well as federal action.Google moved rapidly to announce a move allowing employees to work from home after California declared a state of emergency. Facebook soon followed with an even more stringent policy, insisting employees work from home. Both companies have also met with World Health Organization (WHO) officials to talk about responses, and provided early funding for WHO’s Solidarity Response Fund set up in partnership with the UN Foundation and the Swiss Philanthropy Foundation.America’s leading research universities, uniquely positioned with in-house public health and legal expertise, have also been driving preventive efforts. Just days after Washington declared a state of emergency, the University of Washington became the first to announce an end to classroom teaching and move courses online. A similar pattern followed at Stanford, Harvard, Princeton and Columbia - each also following the declaration of a state of emergency.In addition, the decision by the Church of the Latter Day Saints to cancel its services worldwide followed Utah’s declaration of a state of emergency.The gaping hole in the US response has been the national government. President Trump’s declaration of a national emergency came late, and his decision to ban travel from Europe but - at least initially - exclude the UK, created uncertainty and concern that the White House response is as much driven by politics as evidence.This may soon change, as the House of Representatives has passed a COVID-19 response bill that the Senate will consider. These moves are vital to supporting state and private efforts to mobilize an effective response to a national and global crisis.Need for public oversightIn the absence of greater coordination and leadership from the centre, the US response will pale in comparison to China’s dramatic moves to halt the spread. The chaos across America’s airports shows the need for public oversight. As New York State Governor Cuomo pleaded for federal government support to build new hospitals, he said: ‘I can’t do it. You can’t leave it to the states.'When it comes to global pandemics, we may be discovering that authoritarian states can have a short-term advantage, but already Iran’s response demonstrates that this is not universally the case. Over time, the record across authoritarian states as they tackle the coronavirus will become more apparent, and it is likely to be mixed.Open societies remain essential. Prevention requires innovation, creativity, open sharing of information, and the ability to inspire and mobilize international cooperation. The state is certainly necessary, but it is not sufficient alone. Full Article
is In a COVID-19 World, Russia Sticks to International Distancing By feedproxy.google.com Published On :: Sun, 29 Mar 2020 20:49:14 +0000 29 March 2020 Mathieu Boulègue Research Fellow, Russia and Eurasia Programme @matboulegue LinkedIn Google Scholar While a global response is needed against the coronavirus crisis, Russia does not see it as in its interests to contribute – and in fact the Kremlin is using the crisis to further destabilise the world. 2020-03-29-Coronavirus-Russia-Moscow Young woman wearing a face mask in front of St. Basil's Cathedral, Moscow. Photo by ALEXANDER NEMENOV/AFP via Getty Images. Persistent internet rumours claiming the coronavirus outbreak originated from a secret American pharmaceutical company with the aim of destroying China from within were quickly discredited. Pop culture fans recognised the supposed activities of the Umbrella Corporation as being from the famous Japanese video games series Resident Evil.However, although fake news, it can likely be attributed to Russian trolls conducting this and other similar activities online, especially when considered within the wider context of how the Russian regime is using this worldwide crisis to further destabilize the West and test its resolve.Russian trolls never sleepRussia’s COVID-19 related actions first and foremost take the form of a vast information warfare campaign, with media outlets simultaneously downplaying the threat of the pandemic - ‘it is less dangerous than seasonal flu’ - while stoking fear about what is happening elsewhere in Europe.For the domestic audience in Russia, some media are reporting the pandemic marks the collapse of the Western world and liberalism altogether, calling it a form of collective punishment. Other point out how fast liberal democracies have curbed individual and entrepreneurial freedoms in order to slow down the viral outbreak, and seek to diminish the credibility of the Western response to the crisis.Exploiting the coronavirus crisis in this way is a new low in Russia’s wider political warfare campaign to undermine global governance overall, as these activities are detrimental to people's very safety. For example, in Ukraine, it is thought a Russian-engineered disinformation operation may have caused the outburst of violence in the city of Novi Sanzhary following the arrival of evacuees from China.In the military realm, fake news has been targeting the US-led multinational exercise DEFENDER-Europe 2020. The Russian leadership criticized the exercise as an offensive ‘anti-Russian scenario’ but then used accompanying propaganda that it could actively facilitate the spread of COVID-19 across Europe because of the arrival and movement of large numbers of troops.The large-scale drills were planned to involve 18 participating nations and should have taken place across ten European countries from April to May 2020. But the exercise has now been scaled down – as has the Russian disinformation targeting it.And while the world is pre-occupied with managing COVID-19, Moscow is able to grow bolder in its provocations. Recent air incursions were reported into Irish controlled airspace as well as over the North Sea. Although this practice is - unfortunately - routine as part of Russian constant military sabre-rattling, it does increase the risk of tactical errors and miscalculation.Self-isolation, Kremlin styleMeanwhile, just when a global response is needed to fight the pandemic, Moscow’s response has been, at best, self-serving. On March 22, Russian military reportedly started sending medical equipment and supplies to Italy. While the nature and the scope of this assistance can be doubted, it still represents a charm offensive for Russia to be brought back in from the cold in Europe - since successive Italian leaderships have been accommodating to the Kremlin. And sending virologists to Italy might also be a useful learning curve for Russia’s regime.But within Russia itself, Vladimir Putin does have to face the problem that, on top of all the projected social and healthcare costs, the coronavirus is also having negative political consequences. On March 25, the ‘popular vote’ - a mock referendum designed to rubber-stamp Putin’s recent constitutional changes - was pushed back. And the Ministry of Communications has been forced to postpone a major exercise aimed at ensuring the ‘stable and safe operation of Runet’ - namely eliminating vulnerabilities in the Russian ‘sovereign’ internet to potential external threats.Certainly it would be naive to believe Moscow will put self-interest to one side during this pandemic. ‘International distancing’ is not new for the Kremlin, and Russia has been practising self-isolation since at least 2008 through its own actions, most notably in Georgia and Ukraine.Its self-perception as a ‘besieged fortress’ is being reinforced by this crisis and Russia will, at the very least, likely come out of the crisis feeling vindicated in its view that internationalism is dying or already dead.With the health systems of many countries under massive strain, and societal resilience being tested by social distancing, the Kremlin continues to probe for weaknesses, and is also carefully watching other countries’ responses to the crisis in terms of adaptation and mobilization of resources.COVID-19 provides a major intelligence-gathering opportunity for Moscow to learn how well others can implement wartime-like planning in peacetime. In a rapidly changing world, Russia is still Russia. Full Article
is COVID-19 Impact on Refugees is Also Political By feedproxy.google.com Published On :: Tue, 31 Mar 2020 10:53:27 +0000 31 March 2020 Dr Lina Khatib Director, Middle East and North Africa Programme @LinaKhatibUK The spread of coronavirus in the Levant puts Syrian as well as other refugees and internally displaced people at particular risk because of the policies and practices of the authorities. 2020-03-31-Covid19-lebanon The word Corona written in the sand on the beach in Lebanon's southern city of Saida. amid the spread of coronavirus in the country. Photo by MAHMOUD ZAYYAT/AFP via Getty Images. As Lebanon strains to contain COVID-19, it is not clear which governmental public health policies apply to refugees. The government announced free testing for coronavirus in the public Rafiq Hariri University Hospital in Beirut but has not mentioned if refugees are eligible.Lebanon’s coronavirus containment strategy is based on self-reporting and, given incidents of forced deportation and harassment of Syrian refugees from both the authorities and local communities, it is certainly less likely refugees would present themselves to the health authorities for fear of deportation.Despite agreeing a Lebanon Crisis Response Plan with the UN for refugees, different ministries were left to implement it without coordination, just as Lebanese politicians from all sides started trying to rally popular support for ridding Lebanon from refugees - in particular from Syria, who Lebanese leaders say are causing a strain on the country’s already weak infrastructure.This finger pointing is coupled with the leaders’ own complete disregard for the rampant corruption and lack of accountability within Lebanon’s political class, which contribute to the weakening of the country’s infrastructure.For refugees who do find themselves back in Syria, there are different challenges according to which area they are in. In the north-east, the WHO and international NGOs (INGOs) negotiate with both Kurdish authorities as well as the government - each presenting its own hurdles.Kurdish authorities in northeast Syria have closed the Semalka border with Iraqi Kurdistan, posing a serious dilemma for INGOs offering services in north-east Syria but concerned about their staff safety whose movement is now curtailed.The government of Syria has stipulated all emergency response must go through its ministries. But this limits what the WHO can do in the country and gives Syrian authorities the ability to block ‘cross-line aid’ which goes from government-controlled to non-government areas.Despite reports that doctors raised the alarm about suspected cases well before patient zero was confirmed, the government appears to be either covering up the actual extent of the spread of COVID-19 or failing to respond. Some limited testing kits have arrived but testing has barely started.The WHO’s Syria plan is divided into three regions (north-west, north-east, and areas under government control). But concerns remain as to how workable such a decentralized plan is because of the government’s practices. In January, the UN Security Council did not renew the cross-border response resolution for the Yaroubiye border crossing between Syria and Iraq that the WHO was using to send medical supplies into north-east Syria.Syrian authorities do not permit recently authorized ‘cross-line’ responders to engage with non-government authorities in areas outside regime control. This essentially voids the authorization to work cross-line as it is practically impossible to implement programs. The WHO has sought approval from the Syrian Ministry of Foreign Affairs to move medical supplies by land to north-east Syria.While promising facilitation, the Ministry’s reply comes with conditions of seeking detailed approval for every shipment. When Eastern Ghouta was under siege, similar conditions led to certain supplies being removed from UN/ICRC convoys to Eastern Ghouta, and there is no guarantee this will not happen again.Due to lack of capacity in north-east Syria, coronavirus tests conducted by the WHO there must be processed through the Central Public Health Laboratory in Damascus. Samples are transported twice a week from Qamishli to Damascus but no results were ever received from Damascus for those tests.While the WHO is able to coordinate access to north-west Syria with the Turkish authorities, the prospective coronavirus testing capacity in the Idlib region is low – despite claims that thousands of kits are arriving, a lack of resource on the ground means potentially only 20 tests per day could be done in an area inhabited by an estimated three million people.Following the recently announced ceasefire in the area, many internally displaced people are returning from the Turkish border to their homes in the north-west, but such mass movement increases the risk of coronavirus spreading. People also continue to move between Syria, Iraq, Turkey and Lebanon, posing a challenge to the WHO’s COVID-19 response in the Levant, as the WHO has distinct response plans for each country in the region and it is difficult to coordinate across these plans.Challenges face refugees even if they head towards Europe due to the potential for conflation between migration control and coronavirus outbreak control. Aurelie Ponthieu, Coordinator for Forced Migration at Médecins Sans Frontières (MSF) says there is a risk some countries could use COVID-19 to impose draconian measures towards asylum seekers.The crisis has also put a halt to search and rescue operations in the Mediterranean because European countries are not allowing boats carrying migrants to disembark under the pretext of limiting the spread of coronavirus. And for migrants who already made it - such as in Greece - they are now being put in collective quarantines in asylum centers, often with poor medical facilities.Ponthieu also reports that migrants being quarantined on overcrowded navy ships docked in Greek ports, making social distancing impossible. And she is concerned the Greek authorities are imposing a curfew on asylum seekers but not on the local population.UNHCR is stressing that people’s right of asylum must not be overruled by concerns about the spread of coronavirus, while local and international NGOs across the Levant are trying to coordinate their advocacy on lifting restrictions on freedom of movement for humanitarian workers and on other policies and practices by authorities in the region which are adversely affecting refugee and other vulnerable communities.The international community must not lose sight of the impact of the crisis on refugees and migrants. It is not enough simply to supply humanitarian and medical assistance without paying attention to the policies and practices of the different authorities who have direct control over the fate of vulnerable communities.The author would like to thank Aurelie Ponthieu and the two INGO field workers who all agreed to be interviewed to inform this analysis piece.

is Supporting NHS Cybersecurity During COVID-19 is Vital By feedproxy.google.com Published On :: Thu, 02 Apr 2020 12:09:33 +0000 2 April 2020 Joyce Hakmeh Senior Research Fellow, International Security Programme; Co-Editor, Journal of Cyber Policy @joycehakmeh LinkedIn The current crisis is an opportunity for the UK government to show agility in how it deals with cyber threats and how it cooperates with the private sector in creating cyber resilience. 2020-04-02-NHS-nurse-tech-cyber Nurse uses a wireless electronic tablet to order medicines from the pharmacy at The Queen Elizabeth Hospital, Birmingham, England. Photo by Christopher Furlong/Getty Images. The World Health Organization, US Department of Health and Human Services, and hospitals in Spain, France and the Czech Republic have all suffered cyberattacks during the ongoing COVID-19 crisis.In the Czech Republic, a successful attack targeted a hospital with one of the country’s biggest COVID-19 testing laboratories, forcing its entire IT network to shut down, urgent surgical operations to be rescheduled, and patients to be moved to nearby hospitals. The attack also delayed dozens of COVID-19 test results and affected the hospital’s data transfer and storage, affecting the healthcare the hospital could provide.In the UK, the National Health Service (NHS) is already in crisis mode, focused on providing beds and ventilators to respond to one of the largest peacetime threats ever faced. But supporting the health sector goes beyond increasing human resources and equipment capacity.Health services ill-preparedCybersecurity support, both at organizational and individual level, is critical so health professionals can carry on saving lives, safely and securely. Yet this support is currently missing and the health services may be ill-prepared to deal with the aftermath of potential cyberattacks.When the NHS was hit by the Wannacry ransomware attack in 2017 - one of the largest cyberattacks the UK has witnessed to date – it caused massive disruption, with at least 80 of the 236 trusts across England affected and thousands of appointments and operations cancelled. Fortunately, a ‘kill-switch’ activated by a cybersecurity researcher quickly brought it to a halt.But the UK’s National Cyber Security Centre (NCSC), has been warning for some time against a cyber attack targeting national critical infrastructure sectors, including the health sector. A similar attack, known as category one (C1) attack, could cripple the UK with devastating consequences. It could happen and we should be prepared.Although the NHS has taken measures since Wannacry to improve cybersecurity, its enormous IT networks, legacy equipment and the overlap between the operational and information technology (OT/IT) does mean mitigating current potential threats are beyond its ability.And the threats have radically increased. More NHS staff with access to critical systems and patient health records are increasingly working remotely. The NHS has also extended its physical presence with new premises, such as the Nightingale hospital, potentially the largest temporary hospital in the world.Radical change frequently means proper cybersecurity protocols are not put in place. Even existing cybersecurity processes had to be side-stepped because of the outbreak, such as the decision by NHS Digital to delay its annual cybersecurity audit until September. During this audit, health and care organizations submit data security and protection toolkits to regulators setting out their cybersecurity and cyber resilience levels.The decision to delay was made to allow the NHS organizations to focus capacity on responding to COVID-19, but cybersecurity was highlighted as a high risk, and the importance of NHS and Social Care remaining resilient to cyberattacks was stressed.The NHS is stretched to breaking point. Expecting it to be on top of its cybersecurity during these exceptionally challenging times is unrealistic, and could actually add to the existing risk.Now is the time where new partnerships and support models should be emerging to support the NHS and help build its resilience. Now is the time where innovative public-private partnerships on cybersecurity should be formed.Similar to the economic package from the UK chancellor and innovative thinking on ventilator production, the government should oversee a scheme calling on the large cybersecurity capacity within the private sector to step in and assist the NHS. This support can be delivered in many different ways, but it must be mobilized swiftly.The NCSC for instance has led the formation of the Cyber Security Information Sharing Partnership (CiSP)— a joint industry and UK government initiative to exchange cyber threat information confidentially in real time with the aim of reducing the impact of cyberattacks on UK businesses.CiSP comprises organizations vetted by NCSC which go through a membership process before being able to join. These members could conduct cybersecurity assessment and penetration testing for NHS organizations, retrospectively assisting in implementing key security controls which may have been overlooked.They can also help by making sure NHS remote access systems are fully patched and advising on sensible security systems and approved solutions. They can identify critical OT and legacy systems and advise on their security.The NCSC should continue working with the NHS to enhance provision of public comprehensive guidance on cyber defence and response to potential attack. This would show they are on top of the situation, projecting confidence and reassurance.It is often said in every crisis lies an opportunity. This is an opportunity for the UK government to show agility in how it deals with cyber threats and how it cooperates with the private sector in creating cyber resilience.It is an opportunity to lead a much-needed cultural change showing cybersecurity should never be an afterthought.

is Can Morocco Effectively Handle the COVID-19 Crisis? By feedproxy.google.com Published On :: Mon, 06 Apr 2020 09:10:24 +0000 6 April 2020 Dr Mohammed Masbah Associate Fellow, Middle East and North Africa Programme @MasbahMohammed LinkedIn Google Scholar Anna Jacobs Senior Research Assistant, Brookings Doha Center The Moroccan government is capitalizing on a burst of unity, social solidarity and public support in the face of a crisis. However, if it fails to effectively mitigate the public health and economic impacts of the COVID-19 pandemic, this spirit of solidarity and cooperation will not last long. GettyImages-1208907580.jpg A general view of empty stores during curfew as a precaution against the new type of coronavirus (COVID-19) in Rabat, Morocco on 1 April 2020. Photo by Jalal Morchidi/Anadolu Agency via Getty Images. In Morocco, the COVID-19 pandemic has increased public trust in government, but people still have doubts about the effectiveness of the healthcare system. According to a recent study conducted by the Moroccan Institute for Policy Analysis (MIPA), the majority of Moroccans surveyed are generally satisfied with the measures taken by the government to battle the coronavirus. However, the same survey also shows that Moroccans do not have confidence in the healthcare sector’s ability to respond to this pandemic.The positive perceptions of the government’s response can be explained by the swift and strict measures enacted. King Mohammed VI held a high-level meeting with the prime minister, the minister of health, and top security officials on 17 March and a few days later, on 20 March, the Moroccan government declared a state of health emergency and began to implement aggressive measures to contain the virus.This has included closing airports, schools, mosques, cafés and shops – with the exception of food markets – preventing large gatherings, as well as strict guidelines to ensure social distancing. As of 2 April, nearly 5000 people have been arrested for violating the state of health emergency.In order to address urgent medical needs and to mitigate the economic impact of the pandemic, the King ordered the creation of an emergency fund, raising more than 32.7 billion Moroccan Dirhams ($3.2 billion). The Ministry of Finance will begin to make cash transfers to vulnerable citizens, and especially those who have lost their jobs. However, the stipulations surrounding these cash transfers will be decided in the coming weeks.Updates about the virus are communicated daily by the Ministry of Health, despite growing criticism of its communication strategy. As of 4 April, Moroccan authorities have confirmed 883 cases and 58 deaths.Call for national unityIn times like these, there is a call for unity in the face of a national and global crisis, and opposition groups such as Adl wal Ihssan and Rif activists have expressed their support for government measures and have encouraged people to follow the new guidelines and restrictions. However, despite calls to release political prisoners, Moroccan authorities have not indicated that they will do so. This is a missed opportunity vis-à-vis the opposition because it could have served as a way to further strengthen national unity during the crisis.These are all promising signs and point to what is likely to be a short-term burst in unity and institutional trust. However, the institutional weaknesses in governance and the healthcare system have not disappeared, which is why this increase in institutional trust should be taken with a grain of salt.Public trust issuesThis pandemic poses tremendous challenges for governments across the globe, and this holds especially true for states in the Middle East and North Africa region, where citizens do not approve of government performance and do not trust key state institutions. The 2019 Arab Barometer survey found that Moroccans do not trust most of the country’s political institutions (notably the parliament and the Council of Ministers) and the level of satisfaction with the government’s performance remains extremely low.On the public health front, as shown in two of MIPA’s recent surveys, trust in the healthcare system is also very low. Around three-quarters of those surveyed do not trust Moroccan hospitals, highlighting the acute structural problems in the healthcare system. In fact, there is a stark divide between private and public healthcare, as well as a huge gap in access to healthcare facilities between urban and rural areas. Most of the country’s hospitals and doctors are located in major urban areas and the only three laboratories with capabilities for COVID-19 testing are located in Rabat and Casablanca, but even there, testing capacity is very limited.Similar to other countries, there could be a major shortage of doctors and medical equipment throughout Morocco. So far, the Ministry of Finance has said that 2 billion dirhams of the emergency fund will go towards purchasing medical equipment such as beds, ventilators, tests, prevention kits and radiology equipment, but the timeline remains unclear.A vulnerable economyThere is significant concern about the medium- and long-term economic impact of the virus. Two of the country’s key economic sectors have already been hit hard: agriculture and tourism. The agricultural sector was already struggling due to the impact of drought, while the coronavirus pandemic is likely to impact Morocco’s tourism industry not just this year, but well into 2021. In terms of government response, the emergency fund is a strong start, but questions surrounding the management of these funds have already been raised.The most vulnerable parts of the population have been affected by the economic crisis because of the country’s bulging informal sector – in which most people work - and a very weak private sector. In fact, two-thirds of the workforce are not covered by a pension plan, almost half of the working population does not currently benefit from medical coverage and there is no social care system for vulnerable parts of the population. As of 1 April, more than 700,000 workers have lost their jobs.Moving forward?Even if public perceptions of the government’s response are positive at the moment, this is most likely a short-term surge that should not be taken for granted. Despite the efforts made by the government, Morocco’s health system is not equipped to handle this crisis. Even with the new measures that have been implemented, if the spread of the virus gets out of control, more funds, more doctors, and more equipment will be needed. Given the structural weaknesses of the healthcare system, this will be an uphill battle.Moreover, even if the government manages to mitigate the public health impact, the economic consequences will be dire—especially in the tourism industry—and will severely hurt those workers in the informal sector who are living without a safety net. In Morocco, this category represents most of the working population.This crisis highlights that the Moroccan government must urgently tackle its large portfolio of unfinished reforms, notably in healthcare, the economy, and labour rights. So far, the government is capitalizing on the spirit of unity, social solidarity and public support. The future trajectory of the pandemic and the effectiveness of governance will determine if this spirit of solidarity will last. If the government fails to effectively mitigate the public health and economic impacts of this pandemic, this solidarity and cooperation will not last long. Full Article
is COVID-19: America's Looming Election Crisis By feedproxy.google.com Published On :: Wed, 08 Apr 2020 08:31:53 +0000 8 April 2020 Dr Lindsay Newman Senior Research Fellow, US and the Americas Programme @lindsayrsnewman LinkedIn Planning now is essential to ensure the legitimacy of November’s elections is not impacted by COVID-19, as vulnerabilities are becoming ever more apparent if voting in person is restricted. 2020-04-08-COVID-US-election Roadside voting in Madison, Wisconsin in April 2020. Because of coronavirus, the number of polling places was drastically reduced. Photo by Andy Manis/Getty Images. The COVID-19 epidemic has hit every aspect of American life. The upcoming November general elections will not be immune to the virus’ impact and may be scheduled to happen while the pandemic remains active, or has returned.There is a danger the epidemic forces change to the way voting takes place this fall, amplifying risks around election security and voter suppression that ultimately undermine the integrity of the elections.This is further highlighted by the US Supreme Court’s last-minute ruling along ideological lines to restrict an extension on the absentee voting period in the Wisconsin Democratic presidential primary despite the level of infections in the state, forcing voters into a trade-off between their health and their right to vote. The US could be thrown into a political crisis in addition to the health and economic crises it already faces.Bipartisan sentimentWhile France, Chile and Bolivia have already postponed elections in the wake of COVID-19, there is a bipartisan sentiment that the US elections should be held as scheduled on the Tuesday after the first Monday in November. This is enshrined not only in America’s sense of itself – having weathered elections during a civil war, a world war and heightened terrorist alert before – but also in its federal law since 1845.Despite increasing appetite for federal elections to go ahead in November, there are serious vulnerabilities, which are already becoming visible as connections are drawn between mail-in voting and voter fraud, greater voter access and disadvantages for the Republican party, and city polling closures and Democratic voter suppression.Concerns around voting access have gained the most attention. If voting in-person is untenable or risky (especially for vulnerable health populations), voters must have alternative means to cast ballots.During negotiations for the Coronavirus Aid, Relief, and Economic Security (CARES) Act, the Democratic caucus in the House of Representatives proposed $4 billion in state election grants and a nationally-mandated period for early voting and no-excuse absentee voting.But the final CARES Act sidestepped the access question and stripped funding to $400 million for election security grants to ‘prevent, prepare for, and respond to coronavirus, domestically or internationally, for the 2020 Federal election cycle’. Without knowing exactly what is in store from a cyber-threat perspective, the actual cost for basic election security upgrades is estimated to be $2.1billion. And that is a pre-COVID-19 calculation.With social-distanced voters likely to be getting more election information than ever from social media, information security is critical to prevent influence from untrustworthy sources. And opportunities for cyber intrusions are likely to increase as states transition to greater virtual registration, plus absentee and mail-in balloting.This will open new doors on well-documented, existing voter suppression efforts. With the Supreme Court clawing back the Voting Rights Act in 2013 - allowing certain states to make changes to election and voting laws without federal pre-clearance - heightened election security requirements, such as exact match campaigns and voter purges, have been used to justify voter suppression.As more vote remotely in the remaining primaries (many now rescheduled for 2 June) and the November general elections, the added burden on states around verification will only increase temptation to set aside ‘non-compliant’ ballots. Especially as some in the Republican Party, including Donald Trump, have advocated a contested view that higher turnout favours the Democratic Party.A fundamental principle of US democracy is that losers of elections respect the result, but history shows that election results have been contested. In 2000, it took weeks for a result to be confirmed in the presidential election. More recently, in the 2018 race for governor in Georgia, allegations of voter suppression raised questions about the validity of the eventual result.Without proper access, security, and verification the electoral process – whenever it takes place – will become vulnerable to questions of integrity. The federal response to the initial spread of COVID-19 saw costly delays which pushed the US into a public health crisis and economic contraction.Any narrative thread of election illegitimacy with November’s elections will further pull apart the fabric of a country already frayed by coronavirus. Federal and state authorities must start planning now for how the US will hold elections in the midst - or immediate aftermath - of COVID-19. Full Article
is Blaming China Is a Dangerous Distraction By feedproxy.google.com Published On :: Wed, 15 Apr 2020 10:50:59 +0000 15 April 2020 Jim O'Neill Chair, Chatham House Chinese officials' initial effort to cover up the coronavirus outbreak was appallingly misguided. But anyone still focusing on China's failings instead of working toward a solution is essentially making the same mistake. 2020-04-15-China-coronavirus-health Medical staff on their rounds at a quarantine zone in Wuhan, China. Photo by STR/AFP via Getty Images. As the COVID-19 crisis roars on, so have debates about China’s role in it. Based on what is known, it is clear that some Chinese officials made a major error in late December and early January, when they tried to prevent disclosures of the coronavirus outbreak in Wuhan, even silencing healthcare workers who tried to sound the alarm.China’s leaders will have to live with these mistakes, even if they succeed in resolving the crisis and adopting adequate measures to prevent a future outbreak. What is less clear is why other countries think it is in their interest to keep referring to China’s initial errors, rather than working toward solutions.For many governments, naming and shaming China appears to be a ploy to divert attention from their own lack of preparedness. Equally concerning is the growing criticism of the World Health Organization (WHO), not least by Donald Trump who has attacked the organization - and threatens to withdraw US funding - for supposedly failing to hold the Chinese government to account. Unhelpful and dangerousAt a time when the top global priority should be to organize a comprehensive coordinated response to the dual health and economic crises unleashed by the coronavirus, this blame game is not just unhelpful but dangerous.Globally and at the country level, we all desperately need to do everything possible to accelerate the development of a safe and effective vaccine, while in the meantime stepping up collective efforts to deploy the diagnostic and therapeutic tools necessary to keep the health crisis under control.Given there is no other global health organization with the capacity to confront the pandemic, the WHO will remain at the center of the response, whether certain political leaders like it or not.Having dealt with the WHO to a modest degree during my time as chairman of the UK’s independent Review on Antimicrobial Resistance (AMR), I can say that it is similar to most large, bureaucratic international organizations.Like the International Monetary Fund (IMF), the World Bank, and the United Nations, it is not especially dynamic or inclined to think outside the box. But rather than sniping at these organizations from the sidelines, we should be working to improve them.In the current crisis, we all should be doing everything we can to help both the WHO and the IMF to play an effective, leading role in the global response. As I have argued before, the IMF should expand the scope of its annual Article IV assessments to include national public-health systems, given that these are critical determinants in a country’s ability to prevent or at least manage a crisis like the one we are now experiencing.I have even raised this idea with IMF officials themselves, only to be told that such reporting falls outside their remit because they lack the relevant expertise. That answer was not good enough then, and it definitely isn’t good enough now.If the IMF lacks the expertise to assess public health systems, it should acquire it. As the COVID-19 crisis makes abundantly clear, there is no useful distinction to be made between health and finance. The two policy domains are deeply interconnected, and should be treated as such.In thinking about an international response to today’s health and economic emergency, the obvious analogy is the 2008 global financial crisis which started with an unsustainable US housing bubble, fed by foreign savings owing to the lack of domestic savings in the United States.When the bubble finally burst, many other countries sustained more harm than the US did, just as the COVID-19 pandemic has hit some countries much harder than it hit China.And yet not many countries around the world sought to single out the US for presiding over a massively destructive housing bubble, even though the scars from that previous crisis are still visible. On the contrary, many welcomed the US economy’s return to sustained growth in recent years, because a strong US economy benefits the rest of the world.So, rather than applying a double standard and fixating on China’s undoubtedly large errors, we would do better to consider what China can teach us. Specifically, we should be focused on better understanding the technologies and diagnostic techniques that China used to keep its - apparent - death toll so low compared to other countries, and to restart parts of its economy within weeks of the height of the outbreak.And for our own sakes, we also should be considering what policies China could adopt to put itself back on a path toward 6% annual growth, because the Chinese economy inevitably will play a significant role in the global recovery.If China’s post-pandemic growth model makes good on its leaders’ efforts in recent years to boost domestic consumption and imports from the rest of the world, we will all be better off.This article was originally published in Project Syndicate Full Article
