No new deaths in China and hope of a plateau in New York

China reported no new coronavirus deaths today for the first time since the outbreak started. Concerns remain about a second wave of infections being brought into China by people arriving from abroad. A total of 32 new cases were confirmed in China today, all of whom had arrived from other countries.

There are hopes that the outbreak may be starting to plateau in New York. The state reported 599 deaths yesterday, on par with previous days. Over 4800 people have died of coronavirus in New York, nearly half the national death toll.

What to read, watch and listen to about coronavirus

New Scientist Weekly features updates and analysis on the latest developments in the covid-19 pandemic. Our podcast sees expert journalists from the magazine discuss the biggest science stories to hit the headlines each week – from technology and space, to health and the environment.

The Rules of Contagion is about the new science of contagion and the surprising ways it shapes our lives and behaviour. The author, Adam Kucharski, is an epidemiologist at the London School of Hygiene and Tropical Medicine, UK, and in the book he examines how things spread and why they stop.

Coronavirus trajectory tracker explained, a video by John Burn-Murdoch for the Financial Times, uses data-visualisation to explain the daily graphs that show how coronavirus cases and deaths are growing around the world.

Contagion: The BBC Four Pandemic is a sober documentary about the progression of a hypothetical pandemic which the BBC simulated in 2017. Fronted by science journalist and TV presenter Hannah Fry, and made with the support of some of the country’s best epidemiologists and mathematical modelers, it’s very relevant to today’s covid-19 pandemic.

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. The Czech government is also considering relaxing lockdown measures, with more shops allowed to reopen from 9 April. Danish prime minister Mette Frederikse, announced last week that restrictions in the country would gradually be lifted after Easter.

Worldwide cases pass one million

Coronavirus cases and deaths have begun to plateau in some European countries, including Italy and Spain, although cases and deaths continue to accelerate in the UK and the US. More people in the UK have died with coronavirus than in China, according to today’s figures from Johns Hopkins University.

In the US hospitals across the country are coming under increasing strain. In Louisiana, the death toll is mounting and there are concerns that the state could run out of hospital beds. New York Governor Andrew Cuomo has ordered the National Guard to seize and redistribute any ventilators and personal protective equipment from facilities in the state. Florida has issued a stay-at-home order – over the past week cases in the state have been growing by hundreds daily.

There have now been more than one million confirmed coronavirus cases diagnosed across the globe, though the true number of cases will be much higher. More than 55,000 people have died from covid-19.

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.

Other coronavirus developments

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.

UK government to cover affected workers’ wages

The UK government has announced that it will pay 80 per cent of wages up to £2,500 a month for employees who are not working during the coronavirus outbreak. The scheme will last at least three months, backdated to 1 March, and it could be extended for longer if necessary. UK pubs and restaurants will also close, mirroring moves in other countries around the world.

Coronavirus vaccine trials get underway 

Researchers at the University of Oxford in the UK are planning a safety trial for a vaccine against coronavirus in humans. Normally vaccines are tested in animals first, but the trial has been accelerated due to the speed of the coronavirus outbreak.

The first human trial of a vaccine to protect against the covid-19 coronavirus began in the US earlier this week. Other vaccines are in development in Germany and China. Development of an antibody test will also be important to confirm whether people have acquired immunity to the coronavirus.

Other coronavirus developments

China reported no new local coronavirus cases on Wednesday and Thursday. All new cases reported on those two days were from returning travellers who are thought to have contracted the virus while outside China. Nasa’s pollution monitoring satellites have detected a drop in nitrogen dioxide over China which is thought to be partly due to the economic slowdown caused by the coronavirus outbreak.

Schools are to reopen in Singapore but with strict social isolation rules for teachers and children who have recently been abroad. Singapore was one of the first countries to be hit by the virus, in late January.

More lockdowns, border closures and travel restrictions came into effect around the world today. Argentina has imposed a nationwide lockdown and The Philippines has closed borders to non-nationals. Curfew has been imposed in Sri Lanka and a stay-at-home order has been announced in the US state of California.

Police on the Isle of Man arrested a man for allegedly failing to self-isolate, and he could face a fine of up to £10,000 or a three month prison sentence. In the UK, more than 65,000 retired medics are being asked to return to work to help fight the virus.

Documents from the UK’s Scientific Advisory Group for Emergencies (SAGE) suggest that policies to limit the spread of coronavirus would need to be in place for “at least most of a year” in order to prevent healthcare services from becoming overwhelmed.

Coronavirus cases

The worldwide death toll has passed 10,000. The number of confirmed cases is more than 240,000, according to the map and dashboard from Johns Hopkins University, though the true number of cases will be much higher.

Fighting the pandemic: To fight the coronavirus pandemic effectively we need lots more data. Evidence from China so far suggests the way to get on top of the covid-19 outbreak is through rapid testing, isolation and quarantine rather than lockdowns and big travel restrictions.

China reports no new local cases 

For the first time since the outbreak began in late December, China reported that yesterday there were no new local cases of the coronavirus. The lockdown could be lifted in Wuhan, China, once there are no new cases for 14 days, according to the China Daily newspaper. In Italy, the number of people who have died has overtaken China.

The probability of dying after developing symptoms of covid-19 in Wuhan, where the new coronavirus was first detected, was 1.4 per cent as of 29 February, according to a new study. This is lower than was previously thought.

Other coronavirus developments

The European Central Bank has launched an emergency €750 billion package to ease the economic impact of the pandemic, and the Bank of England cut the base interest rate from 0.25% to 0.1%, a record low.

More travel restrictions have been put into place around the world to limit the spread of the coronavirus. Australia and New Zealand have completely closed their borders to foreigners and, in the UK, up to 40 London Underground stations are to be shut. 

On-going lockdowns in France and Italy may be extended into April. India’s population of 1.3 billion have been asked to observe a curfew on Sunday to test the country’s ability to respond to the coronavirus crisis.

At a press briefing, Chris Whitty, chief medical officer for England, said it is now highly improbable that the virus can be made to “go away”. Patrick Vallance, the UK’s chief scientific adviser, said it was not possible to put a timeline on when the country will be able to relax its measures for controlling the virus.

In the world of sports, there is still no sign of the Tokyo Olympics being postponed or cancelled, but all English football will be suspended until at least 30 April.

Travel bans come into effect around the world

Germany joined France, Spain and Italy in closing schools, closing non-essential shops and urging its citizens to stay at home as much as possible. As the EU’s new 30-day travel ban came into effect today, thousands of passengers were stopped at Germany’s largest airport, Frankfurt Am Main. Traffic was backed up for more than 60 kilometres on the motorway at the German-Polish border as Poland introduced border controls. The FT reports that London could be “locked down” imminently with similarly strict rules on being outdoors to that seen in Spain and Italy.

Several countries in Africa have also announced travel bans, including Nigeria, and, in South America, Brazil has closed its border to Venezuela. The US-Canada border will also close temporarily.

Governments around the world, including in Australia, Indonesia, New Zealand, Norway and the United Arab Emirates, are now urging their citizens to return home as the coronavirus spreads.

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.

The UK government has announced that everyone in the country should avoid “non-essential” travel and should voluntarily avoid pubs, clubs and theatres.

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.

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.
