Coronavirus: Public Health Emergency or Pandemic – Does Timing Matter?

Senior Consulting Fellow, Global Health Programme
The World Health Organization (WHO) has been criticized for delaying its announcements of a public health emergency and a pandemic for COVID-19. But could earlier action have influenced the course of events?

The World Health Organization (WHO) declared the spread of COVID-19 to be a Public Health Emergency of International Concern (PHEIC) on January 30 this year and then characterized it as a pandemic on March 11.

Declaring a PHEIC is the highest level of alert that WHO is obliged to declare, and is meant to send a powerful signal to countries of the need for urgent action to combat the spread of the disease, mobilize resources to help low- and middle-income countries in this effort and fund research and development on needed treatments, vaccines and diagnostics. It also obligates countries to share information with WHO.

Once the PHEIC was declared, the virus continued to spread globally, and WHO began to be asked why it had not yet declared the disease a pandemic. But there is no widely accepted definition of a pandemic, generally it is just considered an epidemic which affects many countries globally.

Potentially more deadly

The term has hitherto been applied almost exclusively to new forms of flu, such as H1N1 in 2009 or Spanish flu in 1918, where the lack of population immunity and absence of a vaccine or effective treatments makes the outbreak potentially much more deadly than seasonal flu (which, although global, is not considered a pandemic).

For COVID-19, WHO seemed reluctant to declare a pandemic despite the evidence of global spread. Partly this was because of its influenza origins — WHO’s emergency programme executive director said on March 9 that ‘if this was influenza, we would have called a pandemic ages ago’.

He also expressed concern that the word traditionally meant moving — once there was widespread transmission — from trying to contain the disease by testing, isolating the sick and tracing and quarantining their contacts, to a mitigation approach, implying ‘the disease will spread uncontrolled’.

WHO’s worry was that the world’s reaction to the word pandemic might be there was now nothing to be done to stop its spread, and so countries would effectively give up trying. WHO wanted to send the message that, unlike flu, it could still be pushed back and the spread slowed down.

In announcing the pandemic two days later, WHO’s director-general Dr Tedros Adhanom Ghebreyesus reemphasised this point: ‘We cannot say this loudly enough, or clearly enough, or often enough: all countries can still change the course of this pandemic’ and that WHO was deeply concerned ‘by the alarming levels of inaction’.

The evidence suggests that the correct message did in fact get through. On March 13, US president Donald Trump declared a national emergency, referring in passing to WHO’s announcement. On March 12, the UK launched its own strategy to combat the disease. And in the week following WHO’s announcements, at least 16 other countries announced lockdowns of varying rigour including Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Hungary, Netherlands, Norway, Poland, Portugal, Serbia, Spain and Switzerland. Italy and Greece had both already instituted lockdowns prior to the WHO pandemic announcement.

It is not possible to say for sure that WHO’s announcement precipitated these measures because, by then, the evidence of the rapid spread was all around for governments to see. It may be that Italy’s dramatic nationwide lockdown on March 9 reverberated around European capitals and elsewhere.

But it is difficult to believe the announcement did not have an effect in stimulating government actions, as was intended by Dr Tedros. Considering the speed with which the virus was spreading from late February, might an earlier pandemic announcement by WHO have stimulated earlier aggressive actions by governments?

Declaring a global health emergency — when appropriate — is a key part of WHO’s role in administering the International Health Regulations (IHR). Significantly, negotiations on revisions to the IHR, which had been ongoing in a desultory fashion in WHO since 1995, were accelerated by the experience of the first serious coronavirus outbreak — SARS — in 2002-2003, leading to their final agreement in 2005.

Under the IHR, WHO’s director-general decides whether to declare an emergency based on a set of criteria and on the advice of an emergency committee. IHR defines an emergency as an ‘extraordinary event that constitutes a public health risk through the international spread of disease and potentially requires a coordinated international response’.

In the case of COVID-19, the committee first met on January 22-23 but were unable to reach consensus on a declaration. Following the director-general’s trip to meet President Xi Jinping in Beijing, the committee reconvened on January 30 and this time advised declaring a PHEIC.

But admittedly, public recognition of what a PHEIC means is extremely low. Only six have ever been declared, with the first being the H1N1 flu outbreak which fizzled out quickly, despite possibly causing 280,000 deaths globally. During the H1N1 outbreak, WHO declared a PHEIC in April 2009 and then a pandemic in June, only to rescind both in August as the outbreak was judged to have transitioned to behave like a seasonal flu.

WHO was criticized afterwards for prematurely declaring a PHEIC and overreacting. This then may have impacted the delay in declaring the Ebola outbreak in West Africa as a PHEIC in 2014, long after it became a major crisis. WHO’s former legal counsel has suggested the PHEIC — and other aspects of the IHR framework — may not be effective in stimulating appropriate actions by governments and needs to be reconsidered.

When the time is right to evaluate lessons about the response, it might be appropriate to consider the relative effectiveness of the PHEIC and pandemic announcements and their optimal timing in stimulating appropriate action by governments. The effectiveness of lockdowns in reducing the overall death toll also needs investigation.

12-LOX catalyzes the oxidation of 2-arachidonoyl-lysolipids in platelets generating eicosanoid-lysolipids that are attenuated by iPLA2{gamma} knockout [Signal Transduction]

The canonical pathway of eicosanoid production in most mammalian cells is initiated by phospholipase A2-mediated release of arachidonic acid, followed by its enzymatic oxidation resulting in a vast array of eicosanoid products. However, recent work has demonstrated that the major phospholipase in mitochondria, iPLA2γ (patatin-like phospholipase domain containing 8 (PNPLA8)), possesses sn-1 specificity, with polyunsaturated fatty acids at the sn-2 position generating polyunsaturated sn-2-acyl lysophospholipids. Through strategic chemical derivatization, chiral chromatographic separation, and multistage tandem MS, here we first demonstrate that human platelet-type 12-lipoxygenase (12-LOX) can directly catalyze the regioselective and stereospecific oxidation of 2-arachidonoyl-lysophosphatidylcholine (2-AA-LPC) and 2-arachidonoyl-lysophosphatidylethanolamine (2-AA-LPE). Next, we identified these two eicosanoid-lysophospholipids in murine myocardium and in isolated platelets. Moreover, we observed robust increases in 2-AA-LPC, 2-AA-LPE, and their downstream 12-LOX oxidation products, 12(S)-HETE-LPC and 12(S)-HETE-LPE, in calcium ionophore (A23187)-stimulated murine platelets. Mechanistically, genetic ablation of iPLA2γ markedly decreased the calcium-stimulated production of 2-AA-LPC, 2-AA-LPE, and 12-HETE-lysophospholipids in mouse platelets. Importantly, a potent and selective 12-LOX inhibitor, ML355, significantly inhibited the production of 12-HETE-LPC and 12-HETE-LPE in activated platelets. Furthermore, we found that aging is accompanied by significant changes in 12-HETE-LPC in murine serum that were also markedly attenuated by iPLA2γ genetic ablation. Collectively, these results identify previously unknown iPLA2γ-initiated signaling pathways mediated by direct 12-LOX oxidation of 2-AA-LPC and 2-AA-LPE. This oxidation generates previously unrecognized eicosanoid-lysophospholipids that may serve as biomarkers for age-related diseases and could potentially be used as targets in therapeutic interventions.

Online Study Group: All Lukashenka’s Men: The Belarusian Ruling Elite and Why It Matters

Invitation Only Research Event

22 April 2020 - 2:30pm to 4:00pm

Event participants

Ryhor Astapenia, Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme, Chatham House
Chair: James Nixey, Programme Director, Russia and Eurasia, Chatham House

Soon after assuming power in 1994, President Aliaksandr Lukashenka turned his back on democratic norms and overpowered the Belarusian political elite. However, the influence of the governing elite in Belarus is growing again. It seems likely that the current governing class could rule the country after Lukashenka leaves. It is thus important to study Belarusian elites not only to understand the current regime, but also to better forecast and navigate the political system that will one day replace it. 

This study group aims to disentangle how the Belarusian political system works, outline the types of individuals that make up the Belarusian ruling elite, assess the interaction of the elite and institutions with the West, and suggest changes that Western political actors might make to their approach to the Belarusian ruling class.

Finance plays a key role in enabling climate change mitigation and adaptation. It is also a contested issue in the UN climate negotiations. The fourth event in the Chatham House COP26 Diplomatic Briefing Series will explore the politics of climate finance in the context of the COP, and provide a comprehensive update of the main climate finance-related negotiation items and processes. The topic is particularly timely given that the UK Government has made climate finance one of its top thematic priorities for COP26 and that 2020 constitutes the deadline for developed countries to mobilise USD 100 billion per year to support climate action in developing countries.

Slc43a3 is a regulator of free fatty acid flux [Research Articles]

Adipocytes take up long chain FAs through diffusion and protein-mediated transport, whereas FA efflux is considered to occur by diffusion. To identify potential membrane proteins that are involved in regulating FA flux in adipocytes, the expression levels of 55 membrane transporters without known function were screened in subcutaneous adipose samples from obese patients before and after bariatric surgery using branched DNA methodology. Among the 33 solute carrier (SLC) transporter family members screened, the expression of 14 members showed significant changes before and after bariatric surgery. One of them, Slc43a3, increased about 2.5-fold after bariatric surgery. Further investigation demonstrated that Slc43a3 is highly expressed in murine adipose tissue and induced during adipocyte differentiation in primary preadipocytes and in OP9 cells. Knockdown of Slc43a3 with siRNA in differentiated OP9 adipocytes reduced both basal and forskolin-stimulated FA efflux, while also increasing FA uptake and lipid droplet accumulation. In contrast, overexpression of Slc43a3 decreased FA uptake in differentiated OP9 cells and resulted in decreased lipid droplet accumulation. Therefore, Slc43a3 seems to regulate FA flux in adipocytes, functioning as a positive regulator of FA efflux and as a negative regulator of FA uptake.

Moreover, we observed robust increases in 2-AA-LPC, 2-AA-LPE, and their downstream 12-LOX oxidation products, 12(S)-HETE-LPC and 12(S)-HETE-LPE, in calcium ionophore (A23187)-stimulated murine platelets. Mechanistically, genetic ablation of iPLA2γ markedly decreased the calcium-stimulated production of 2-AA-LPC, 2-AA-LPE, and 12-HETE-lysophospholipids in mouse platelets. Importantly, a potent and selective 12-LOX inhibitor, ML355, significantly inhibited the production of 12-HETE-LPC and 12-HETE-LPE in activated platelets. Furthermore, we found that aging is accompanied by significant changes in 12-HETE-LPC in murine serum that were also markedly attenuated by iPLA2γ genetic ablation. Collectively, these results identify previously unknown iPLA2γ-initiated signaling pathways mediated by direct 12-LOX oxidation of 2-AA-LPC and 2-AA-LPE. This oxidation generates previously unrecognized eicosanoid-lysophospholipids that may serve as biomarkers for age-related diseases and could potentially be used as targets in therapeutic interventions.

Deletion of fatty acid transport protein 2 (FATP2) in the mouse liver changes the metabolic landscape by increasing the expression of PPAR{alpha}-regulated genes [Lipids]

Fatty acid transport protein 2 (FATP2) is highly expressed in the liver, small intestine, and kidney, where it functions in both the transport of exogenous long-chain fatty acids and the activation of very-long-chain fatty acids. Here, using a murine model, we investigated the phenotypic impacts of deleting FATP2, followed by a transcriptomic analysis using unbiased RNA-Seq to identify concomitant changes in the liver transcriptome. WT and FATP2-null (Fatp2−/−) mice (5 weeks) were maintained on a standard chow diet for 6 weeks. The Fatp2−/− mice had reduced weight gain, lowered serum triglyceride, and increased serum cholesterol levels and attenuated dietary fatty acid absorption. Transcriptomic analysis of the liver revealed 258 differentially expressed genes in male Fatp2−/− mice and a total of 91 in female Fatp2−/− mice. These genes mapped to the following gene ontology categories: fatty acid degradation, peroxisome biogenesis, fatty acid synthesis, and retinol and arachidonic acid metabolism. Targeted RT-quantitative PCR verified the altered expression of selected genes. Of note, most of the genes with increased expression were known to be regulated by peroxisome proliferator–activated receptor α (PPARα), suggesting that FATP2 activity is linked to a PPARα-specific proximal ligand. Targeted metabolomic experiments in the Fatp2−/− liver revealed increases of total C16:0, C16:1, and C18:1 fatty acids; increases in lipoxin A4 and prostaglandin J2; and a decrease in 20-hydroxyeicosatetraenoic acid. We conclude that the expression of FATP2 in the liver broadly affects the metabolic landscape through PPARα, indicating that FATP2 provides an important role in liver lipid metabolism through its transport or activation activities.
