The following is a brief roundup of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. A new antibody test is highly accurate at determining whether people have been infected with the novel coronavirus, according to a study published on Friday in The Journal of Clinical Microbiology. Researchers at the University of Washington School of Medicine found the test, manufactured by Abbott Laboratories, had a specificity rate of 99.9% and a sensitivity rate of 100%, suggesting little chance of incorrectly diagnosing a healthy person as having been infected and virtually no chance of a false negative readout.

Smartphones can be used to digitally trace Covid-19. But not if the public don’t download an app over privacy fears – or find it won’t work on their device

The idea of the NHS tracing app is to enable smartphones to track users and tell them whether they interacted with someone who had Covid-19. Yet this will work only if large proportions of the population download the app. No matter how smart a solution may appear, mass consent is required. That will not be easy. Ministers and officials have failed to address the trade-offs between health and privacy by being ambiguous about the app’s safeguards.

Instead of offering cast-iron guarantees about the length of time for which data would be held; who can access it; and the level of anonymity afforded, we have had opacity and obfuscation. It is true that we are dealing with uncertainties. But without absolute clarity about privacy the public is unlikely to take up the app with the appropriate gusto.

Some weeks ago my main worries were around my GCSEs. Now I hear every day about deaths from Covid-19

It is the sixth week of lockdown, and for many people things are getting progressively more intense. Most families are physically distancing at home. People are only leaving the house for their weekly shop – and spending a lot of that time waiting in the queue – or to exercise once a day.

In my family things are a bit different. Our driveway is usually empty during the day as my parents, who are doctors, go in to work. It is difficult to imagine how only some weeks ago my main worries were around my GCSEs. Now every day, I hear about deaths from coronavirus. I cannot help but feel a surge of fear for my parents as I watch these updates with my brother. I’m painfully aware of the many healthcare workers who have lost their lives.

Lawyers say failure to provide adequate PPE may amount to corporate manslaughter

The deaths of more than 50 hospital and care home workers have been reported to Britain’s health and safety regulator, which is considering launching criminal investigations, the Guardian has learned.

The Health and Safety Executive (HSE), which investigates the breaking of safety at work laws, has received 54 formal reports of deaths in health and care settings “where the source of infection is recorded as Covid-19”. These are via the official reporting process, called Riddor: Reporting of Injuries, Diseases and Dangerous Occurrences.

Sage told widespread use of antibody tests could lead to criminal behaviour, papers reveal

Downing Street’s scientific advisers feared people might intentionally seek to contract coronavirus and that a black market in fake test results could emerge if employers allowed workers to return only when they had a positive antibody test.

The Scientific Advisory Group for Emergencies, known as Sage, was warned last month by its behavioural psychology subgroup that the widespread introduction of antibody tests could lead to a range of potentially dangerous and even criminal “negative behavioural responses” if not handled well.

Recent deaths have stood out, but scientists say they must be interpreted with caution

Amid the steady stream of stories on the lives lost to coronavirus are cases that stand out as remarkable. In the past month, at least two pairs of twins have died in Britain and two pairs of brothers, all within hours or days of each other. But do the deaths point to genetic factors that make some more likely than others to succumb to the disease?

Most scientists believe that genes play a role in how people respond to infections. A person’s genetic makeup may influence the receptors that the coronavirus uses to invade human cells. How resilient the person is to the infection, their general health, and how the immune system reacts will also have some genetic component.

Studies have examined some of the more unusual signs of Covid-19

The World Health Organization lists the most common symptoms of Covid-19 as fever, tiredness and a dry cough. Others include a runny nose, sore throat, nasal congestion, pain, diarrhoea and the loss of sense of taste and/or smell. But there are also other more unusual symptoms that patients have presented.

While the White House looks ahead to reopening houses of worship, most Americans think in-person religious services should be barred or allowed only with limits during the coronavirus pandemic — and only about a third say that prohibiting in-person services violates religious freedom, a new poll finds. States have taken different approaches to resuming gatherings as the coronavirus continues to spread, raising tough questions for religious leaders and the faithful about the appropriate time to return. Among that group is 54-year-old Andre Harris of Chicago, a onetime Sunday school teacher who has shifted his routine from physical worship to the conference calls his church is holding during the pandemic.

In Germany, Chancellor Angela Merkel has been praised for her realism and flexibility when it comes to using her country's reproduction rate to inform lockdown policies. During a press conference on April 16 she explained: "The whole evolution (of the rate) is based on the fact that we assume that we have an infection figure that we can monitor, that we can track and that we have more protection concepts and that, thanks to those, we can loosen restrictions. "But it is thin ice," as Mr Tschentscher (the Hamburg Mayor) said, "or a fragile situation, or really a situation where caution is the order of the day and not overconfidence". The Robert Koch Institute, the government’s health agency, provides regular updates on the country’s rate. On May 5, it stood at 0.71, slightly declining two days later to 0.65. Mrs Merkel’s caution is reflected across the border in France, where the R has fluctuated as the country began easing lockdown measures. On May 1, Jerome Salomon, France's public health chief, said it had risen to between 0.6 and 0.7 on average from 0.5, due to the “progressive return to activity”. But officials are not solely relying on the R, instead reviewing several indicators to decide when to loosen restrictions. At the end of April Spanish authorities said almost all areas of the country had a reproduction number below one, but that they would not consider easing restrictions unless this continues.

Vice President Mike Pence's press secretary has the coronavirus, the White House said Friday, making her the second person who works at the White House complex known to test positive for the virus this week. President Donald Trump, who publicly identified the affected Pence aide, said he was “not worried” about the virus spreading in the White House. Pence spokeswoman Katie Miller, who tested positive Friday, had been in recent contact with Pence but not with the president.

Hackers linked to Iran have targeted staff at U.S. drugmaker Gilead Sciences Inc in recent weeks, according to publicly-available web archives reviewed by Reuters and three cybersecurity researchers, as the company races to deploy a treatment for the COVID-19 virus. In one case, a fake email login page designed to steal passwords was sent in April to a top Gilead executive involved in legal and corporate affairs, according to an archived version on a website used to scan for malicious web addresses. Ohad Zaidenberg, lead intelligence researcher at Israeli cybersecurity firm ClearSky, who closely tracks Iranian hacking activity and has investigated the attacks, said the attempt was part of an effort by an Iranian group to compromise email accounts of staff at the company using messages that impersonated journalists.

As coronavirus-induced economic pain grew around the world, some U.S. states moved forward Friday with plans to reopen their economies, while European countries held muted commemorations to mark the 75th anniversary of the end of World War II on the continent. Around the U.K., residents were encouraged to stand on their doorsteps and sing together while socially distanced to commemorate the Allies' victory over Nazi Germany. Meanwhile, South Korea, seen as a model for containing COVID-19, ordered nightclubs closed for a month and considered delaying a school restart after an uptick in coronavirus cases.

The United States on Friday objected to a proposed U.N. resolution on the coronavirus pandemic after diplomats said it had agreed to compromise language with China that didn’t directly mention the World Health Organization, an issue of growing dispute between the world’s two major economic powers. The U.S. objection to the Security Council resolution drafted by France and Tunisia reflects rising tensions between Washington and Beijing. It also leaves the U.N.’s most powerful body impotent on reacting to the greatest crisis facing the world — and unable to back Secretary-General Antonio Guterres’ March 23 call for global cease-fires to tackle the COVID-19 pandemic, which diplomats said all 15 Security Council members agree on and is the main point of the resolution.

A hard Brexit is more likely due to the coronavirus crisis because Britain and the European Union have made so little progress in talks, Germany's foreign minister has said. Heiko Maas said that negotiations between Britain and the EU so far on the future trade relationship had yielded few gains with the UK disregarding the political declaration, which he said was "simply not on". Britain left the EU in January, and talks with the bloc are now focused on setting new trading terms from 2021, when London's status-quo transition period ends. However, the talks quickly hit an impasse when negotiations resumed last month, according to diplomats and officials. "It's worrying that Britain is moving further away from our jointly agreed political declaration on key issues in the negotiations," Mr Maas told the Augsburger Allgemeine newspaper. "It's simply not on, because the negotiations are a complete package as it's laid out in the political declaration." Mr Maas said there was currently neither common ground on how to shape a comprehensive trade deal or on whether to extend the negotiation period beyond the end of the year. "The British government is still refusing to extend the deadline," Mr Maas said. "If it stays that way, we will have to deal with Brexit in addition to the coronavirus at the turn of the year." Simon Coveney, Ireland's foreign minister, said on Friday that the coronavirus pandemic had made an already difficult timeline for a British-European Union trade deal "virtually impossible" and that it would make sense to seek more time.

The beat against Congress has always been that its members are out of touch with average Americans. The result is a wide and deep imprint on the same Congress charged with helping a traumatized nation. “Everyone by now knows someone that had it," said Sen. Amy Klobuchar, D-Minn., whose husband, John Bessler, recovered from a frightening coronavirus infection that sent him to the hospital.

Egypt’s President Abdel-Fattah el-Sissi has approved amendments to the country's state of emergency that grant him and security agencies additional powers, which the government says are needed to combat the coronavirus outbreak. An international rights group condemned the amendments, saying the government has used the global pandemic to “expand, not reform, Egypt’s abusive Emergency Law.” The new amendments allow the president to to take measures to contain the virus, such as suspending classes at schools and universities and quarantining those returning from abroad.

The flight from Italy was one of the last arrivals that day at the Stockholm airport. A Swedish couple in their 50s walked up and loaded their skis into Razzak Khalaf's taxi. It was early March and concerns over the coronavirus were already present, but the couple, both coughing for the entire 45-minute journey, assured Khalaf they were healthy and just suffering from a change in the weather.

On the 75th anniversary of the allied victory in the World War II, The Associated Press spoke to veterans in ex-Soviet countries and discovered that lessons they learned during the war are helping them cope with a new major challenge — the coronavirus pandemic. As they recalled the horrors of the war, they also talked about how strength and tenacity were key to survival both then and now. For Russian World War II veteran Valentina Efremova, the coronavirus pandemic is like going through the war all over again.

Arriving at his retirement home, he immediately went into self-isolation with his wife of 55 years, Jean, who has shown no symptoms of the virus. Embleton, who received an MBE honor from Queen Elizabeth II in 1993 for outstanding service to the Royal Navy, thinks the lockdown rules are too strict for some elderly people.

Iran warned Saturday that coronavirus infections were rising in the southwest despite falls in other regions, as it announced more than 1,500 new confirmed cases. "All provinces are showing a gradual drop in new infections... except for Khuzestan, where the situation is still concerning," health ministry spokesman Kianoush Jahanpour said in televised remarks. The health ministry stopped publishing provincial figures for the coronavirus last month.

Truth can be a casualty when President Donald Trump talks about deaths from the coronavirus in the United States. Pushing to get the country back to normal, Trump also suggested that children are safe from the coronavirus. Germany has done very good.

Couples with dashed wedding plans due to lockdown restrictions have been tying the knot on those tidy green spreads instead, including at least one loaner. Danielle Cartaxo and Ryan Cignarella were supposed to get married in West Orange, New Jersey, on April 11 at a venue with sweeping views of the New York City skyline. The two live in Wayne, Pennsylvania, about 100 miles away, but they had a marriage license issued in West Orange, where Cartaxo lived until she was 5.

Cancellation of the ceremony was the second blow to Putin, who was forced to call off a referendum extending his time in power.

Canada's chief public health officer Theresa Tam was quick to shut down the approach during the daily ministerial update on Monday.

It will be important to one day learn the true origin story of the global pandemic to defend against similar outbreaks in the future, Health Minister Patty Hajdu acknowledged Monday.

The slowing economy due to COVID-19 has allowed solar, wind and hydro power to overtake coal-fired power.

In some cases, the tests may detect old particles of the virus, which may no longer pose a significant threat to the patient or others, scientists say.
