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.”

UK government faces questions over testing

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.

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. Otro vacunas 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.

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.

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.

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.
