Pro-gun groups promote social distancing protests in the US
On Friday, US president Donald Trump posted a series of tweets endorsing protests against social distancing measures in Minnesota, Michigan and Virginia. Over the weekend, more protests took place, including in Denver, Colorado, where nurses stood in the road to block drivers on the way to gatherings.
An investigation by the Washington Post found that the protests were promoted using Facebook groups set up by a small group of far-right, pro-gun activists with ties to the husband of education secretary Betsy DeVos. More than 95 per cent of Democrat and 70 per cent of Republican voters support stay-at-home measures, according to recent polling.
More than 760,000 confirmed coronavirus cases and 40,000 deaths have been reported in the US, according to the latest figures from Johns Hopkins University, although this will be an underestimate.

Death toll in Wuhan revised up by 50 per cent
China has revised the covid-19 death toll in Wuhan up by 50 per cent to 3869 from 2579, saying the total number now accounts for deaths at home and delays in reporting. The Chinese government has denied any cover-up in its handling of the crisis or sharing of data.
French president Emmanuel Macron has questioned China’s management of the outbreak, saying “there are clearly things that have happened that we don’t know about”.
UK social distancing extended
The UK has confirmed that its social distancing measures will last for at least another three weeks and financial support for furloughed employees will be extended for an additional month until the end of June.
Foreign minister Dominic Raab outlined five conditions that need to be met before restrictions will be eased including a “sustained and consistent” fall in the daily death rate and adequate testing.
Health minister Matt Hancock said that 18,000 coronavirus tests are being carried out in the UK each day. The country is now less than two weeks away from the government’s target of doing 100,000 daily tests. Hancock said the vast majority of the tests so far were NHS swab tests for patients and key workers, and that antibody tests – which could show a person has had the virus and is immune – were still not ready for clinical use. In March, the government paid £16 million up front to two Chinese companies for untested antibody tests which were subsequently found not to work.
The public will not be told to wear cloth face masks unless scientists say it is necessary, according to transport minister Grant Shapps. It is unclear whether cloth face masks minimise the spread of the coronavirus, but many places around the world, including New York, have made it mandatory to wear them outside.

The head of the International Monetary Fund, Kristalina Georgieva, has said that the UK and European Union should not refuse to extend the negotiating period for a post-Brexit trade deal, as this would add to uncertainty during the coronavirus pandemic. If a deal is not signed by 31 December 2020, the UK and EU would trade on World Trade Organization terms which would include new taxes and restrictions on traded goods.
The UK will need to keep a “significant level” of social distancing until a coronavirus vaccine has been found, according to Neil Ferguson, an epidemiologist advising the government whose research previously influenced changes to the UK’s coronavirus policy. However, Mark Woolhouse, an epidemiologist at the University of Edinburgh, UK, recently told New Scientist that waiting for a vaccine wasn’t a good plan: “I do not think waiting for a vaccine should be dignified with the word ‘strategy’. It’s not a strategy, it’s a hope.”
A new type of ventilator to support covid-19 patients has received regulatory approval in the UK, and the government has confirmed an order for 15,000.

Why are men more likely to get worse symptoms and die from coronanvirus? The difference does not appear to be caused by differential rates of infection: a New York study, for example, found that equal numbers of men and women catch the virus. But men are more likely to progress to severe illness and death.
15 April
Worldwide coronavirus cases pass 2 million
There have now been more than 2 million confirmed cases of coronavirus worldwide according to the latest figures from Johns Hopkins University, although the true number of cases will be much higher.

South Korea held an election today under strict social distancing measures to minimise spreading the coronavirus. Voters, many of whom were wearing masks and gloves, were told to stand at least 1 metre apart from one another and before entering the polling station, everyone’s temperature was taken. Anyone whose temperature was above 37.5C would be taken to a separate area to vote, away from other people.
US president Donald Trump has said the US will stop giving funding to the World Health Organization (WHO) although it’s still unclear how this change will be implemented.

Some European countries begin easing restrictions
Some European countries are allowing certain non-essential workers to return to their jobs this week, most notably in Spain, which has been one of the countries worst affected by the pandemic. More than 300,000 people who work in construction and manufacturing who cannot work from home will be allowed to return, but schools and restaurants will remain shut.
Austria plans to open most shops including malls and hairdressers from 1 May, but restaurants and hotels will remain closed and cloth face masks will be mandatory for everyone outdoors.

German chancellor Angela Merkel will consider relaxing restrictions across Germany in a meeting on 15 April.
In France, lockdown measures could be extended until 11 May. The UK government is also likely to extend the lockdown and may introduce further restrictions including banning outdoor exercise if people don’t follow social distancing laws. However, the UK lockdown has been less restrictive than in other countries, and has not applied to many jobs that cannot be conducted from home, including construction. According to the Office for National Statistics, more than a fifth of deaths in England and Wales the week ending 3 April were linked to coronavirus.
In the US, which has the most confirmed cases and deaths of any country in the world, president Donald Trump has said he wants to ease restrictions from 1 May. In a press conference yesterday he claimed he had “total” authority to lift the lockdown, drawing criticism from state governors including New York governor Andrew Cuomo who said Trump was acting like a “king”.
India’s national lockdown will be extended until at least 3 May, according to prime minister Narendra Modi. The lockdown was originally scheduled to end today.

The virus is thought to have originated in bats, although it is not known if the virus crossed over into other animals before it first spread to humans.
Researchers are investigating whether people who have recently recovered from mild coronavirus infections can become infected again. A preliminary study found that 175 recently-recovered individuals had unexpectedly low levels of antibodies against the virus, which might be too low to provide protection.

Daily death tolls decline in Europe’s worst-hit countries as US braces for “peak death week”
In Europe, Italy and Spain have the highest number of confirmed cases and deaths from covid-19, but infections appear to be slowing and the number of new deaths in both countries has been falling for several days in a row. The number of deaths in one day in Spain peaked on Thursday last week, when 950 people died; yesterday, the Spanish government reported 637 deaths. The number of deaths in Italy peaked with 919 deaths on 27 March, compared with 525 deaths reported yesterday.
The lockdown measures in both countries have been extended, with restrictions in Spain set to last until at least 25 April. Silvio Brusaferro, head of Italy’s public health institute, says that the lockdown measures have led to a “significant slowdown in the spread” of the virus.
The US, which is now the worst-affected country in the world, is bracing for “peak death week”, according to White House officials. US surgeon general, Jerome Adams, warned that this will be “the hardest and the saddest week of most Americans’ lives.” US president Donald Trump pointed to the signs of change in Europe as “the light at the end of the tunnel.”
Some lockdown measures are gradually being lifted in Europe including in Austria which will start reopening non-essential shops, with strict hygiene measures, next week.

UK government faces questions over testing
UK health secretary, Matt Hancock, has pledged to have 100,000 people in England tested per day by the end of the month, following criticism of the UK’s coronavirus testing strategy.
Last month, Boris Johnson promised to move up to 25,000 tests a day with a goal of 250,000, but the UK is still only carrying out around 10,000 coronavirus tests per day.
The new testing target for England includes the introduction of antibody tests, to check whether people have already had the virus, in addition to the existing swab tests, which determine whether a person is currently infected. Antibody tests are still being validated and the government says they won’t roll them out if they aren’t effective.

Following widespread debate over whether people should wear masks in public spaces, a new study has found that surgical face masks could prevent people with symptoms from spreading seasonal human coronaviruses and influenza viruses. It is not yet clear whether these findings could be extended to more severe coronaviruses, such as the covid-19 virus, as the study did not include any participants with covid-19, SARS or MERS.
The White House is expected to advise US citizens in coronavirus hotspots to wear non-medical cloth masks or scarves in public places to help limit the spread of the virus.

WHO on how countries can beat coronavirus
The World Health Organization (WHO) said today a combination of actions by governments including more testing and contact tracing could save lives. “The experience of China and others shows testing and contact tracing, combined with social distancing measures and community mobilisation, when put in place quickly and effectively, can prevent infections and can save lives,” said Hans Kluge at the WHO, during an update on the situation in Europe.
He said the virus could be beaten back by solidarity within communities and between countries. “These are unprecedented times. It is important that countries work together, learn from each other and harmonise the efforts.” Asked by New Scientist about the new measures announced by the UK yesterday, he said he applauded them. “We are pleased to see the UK is getting into the mainstream and stepping up its efforts.”
UK health service under pressure
The UK’s chief scientific advisor Patrick Vallance said today there were probably around 55,000 cases in the country, as official cases jumped to 1950, up 407 on yesterday. By comparison to the roughly 8000 annual deaths from the flu he said it would be a “good outcome” if the UK’s new measures kept coronavirus deaths to below 20,000.
“But I mean it is still horrible; that’s still an enormous number of deaths and an enormous pressure on the health service,” Vallance told MPs on the health and social care committee. Asked why schools had not closed yet as they have in other countries, he said it did not have as much impact as other measures at slowing the virus’s spread, and it had “complicating effects”, including children mixing with grandparents, and the impact on the National Health Service workforce. But he said: “It’s absolutely still on the table.”
The chief executive of the NHS, Simon Stevens, said in response to the crisis the health service was freeing up 30,000 of 100,000 acute care beds for coronavirus patients. He also announced the NHS was stopping all non-urgent surgery from 15 April for three months. Stevens added the UK had access to more than 8000 ventilators for intensive care now, and would soon have around 12,000. But he would not be drawn on whether that would be enough to cope with the peak of the epidemic.

Governments around the world continued to limit travel and close borders. In Europe, Germany partially closed its borders with five countries. The European Commission President Ursula von der Leyen has proposed that there should be a ban on all non-essential travel from outside the European Union for 30 days with exemptions for long-term residents, family members of EU nationals and diplomats.
South Africa and Kenya have imposed strict bans on travel from the worst affected countries.
In the US, flight bans that were extended to the UK and Ireland came into effect. New York, New Jersey and Connecticut forced the closure of restaurants, bars and cinemas. Australia’s prime minister said all travellers arriving in the country would have to self-isolate for 14 days, or risk prison and fines.
In Italy, Lombardy’s governor says the growth of new cases has slowed slightly, but cases in Italy and Spain are still increasing much more rapidly than they did in China, as this (log scale) chart from the Financial Times shows.

Latest on coronavirus from New Scientist
Testing is key: The WHO’s assistant director general Bruce Aylward tells New Scientist that effective quarantine is essential for tackling the coronavirus, but this cannot happen without extensive testing for covid-19. Read our full interview with Bruce Aylward.
Pregnancy and babies: According to initial reports based on small numbers of people, pregnant women and their babies do not seem to be more vulnerable to covid-19 than other groups of people, but doctors warn that it is too early to know for sure. Early reports suggest the virus doesn’t pass from mother to baby via breast milk, but health bodies are advising new mothers who are infected with the virus to take precautions while breastfeeding, such as washing their hands and wearing a facemask.
Psychological responses: When facing uncertainty, we are motivated to take actions that increase our sense of control over the situation, explains psychologist Rachel McCloy. Unfortunately, this can lead to behaviours such as panic buying, which do not actually help to control the virus and may make the situation worse.
