Around 11,000 mink at a farm in Denmark will have to be culled after they were found to be infected with the coronavirus, the country’s authorities have said.

The outbreak is the first in Denmark, the world’s biggest producer of mink skins, but comes shortly after the virus was found at 13 mink farms in the Netherlands, where about 570,000 mink have been ordered culled.

If you’re planning to meet Vladimir Putin in the next few weeks, be warned: you will have to pass through a special disinfectant tunnel to get to the Russian president.

Putin’s official spokesman, Dmitry Peskov, has confirmed a report by Russian state television that three airport-style tunnels have been built for the president: one at his Novo-Ogaryovo residence outside Moscow, where he has reputedly being doing much of his work during the pandemic, and two at the Kremlin.

Hydroxychloroquine: US revokes emergency approval of malaria drug for Covid-19

Food and Drug Administration says drug is unlikely to work against coronavirus and notes heart risks

US regulators revoked the emergency authorization for malaria drugs championed by Donald Trump for treating Covid-19, amid growing evidence they don’t work and could cause serious side effects.

The Food and Drug Administration (FDA) said on Monday the drugs hydroxychloroquine and chloroquine were unlikely to be effective in treating the coronavirus. Citing reports of heart complications, the agency said the drugs’ unproven benefits “do not outweigh the known and potential risks”.

Covid-19 can damage lungs of victims beyond recognition, expert says

Organs of some who die after over a month in hospital sustain ‘complete disruption’, peers told

Covid-19 can leave the lungs of people who died from the disease completely unrecognisable, a professor of cardiovascular science has told parliament.

It created such massive damage in those who spent more than a month in hospital that it resulted in “complete disruption of the lung architecture”, said Prof Mauro Giacca of King’s College London.

Scientists report flaws in WHO-funded study on 2-metre distancing

Mistakes mean findings should not be used as evidence for relaxing rule, say professors

Senior scientists have reported flaws in an influential World Health Organization-commissioned study into the risks of coronavirus infection and say it should not be used as evidence for relaxing the UK’s 2-metre physical distancing rule.

Critics of the distancing advice, which states that people should keep at least 2 metres apart, believe it is too cautious. They seized on the research commissioned by the WHO, which suggested a reduction from 2 metres to 1 would raise infection risk only marginally, from 1.3% to 2.6%.

The Lancet’s editor: ‘The UK’s response to coronavirus is the greatest science policy failure for a generation’

Richard Horton does not hold back in his criticism of the UK’s response to the pandemic and the medical establishment’s part in backing fatal government decisions

There is a school of thought that says now is not the time to criticise the government and its scientific advisers about the way they have handled the Covid-19 pandemic. Wait until all the facts are known and the crisis has subsided, goes this thinking, and then we can analyse the performance of those involved. It’s safe to say that Richard Horton, the editor of the influential medical journal the Lancet, is not part of this school.

An outspoken critic of what he sees as the medical science establishment’s acquiescence to government, he has written a book that he calls a “reckoning” for the “missed opportunities and appalling misjudgments” here and abroad that have led to “the avoidable deaths of tens of thousands of citizens”.

No ‘patient zero’ as Covid-19 came into UK at least 1,300 times

Study prompts further criticism that chances to suppress infection early in outbreak were missed

There was no “patient zero” in the UK’s Covid-19 epidemic, according to research showing that the infection was introduced on at least 1,300 occasions.

The findings, from the Covid-19 Genomics UK consortium, have prompted further criticism that opportunities to suppress the spread of infection in February and March were missed.

Coronavirus live news: pandemic accelerating across Africa; over 2 million cases in US

Shortage of test kits ‘leading to virus spread in Africa’; Mexico confirms record daily infections; Brazil deaths near 40,000

Another 1.5 million people in the US filed for unemployment benefits last week even as states continued to relax their coronavirus quarantine measures, writes Dominic Rushe and Amanda Holpuch in New York.

In just 12 weeks more than 44 million claims have been made for benefits as people lost their jobs. Rehiring appears to have started. Last week the labor department said the unemployment rate had dipped in May to 13.3% from 14.7% in April – although officials said difficulty collecting data meant the figure was probably 3% higher.

Nearly three-quarters of new cases of coronavirus are coming from 10 countries, mostly concentrated in the Americas and south Asia, the director general of the World Health Organization has said.

Speaking at the UN health agency’s member state briefing on Thursday, Tedros Adhanom Ghebreyesus said that the global situation was deteriorating, even as Europe appeared to be over the worst of the outbreak.

More than 7 million cases of Covid-19 have now been reported, and more than 408,000 deaths.

Although the situation in Europe is improving, at the global level, it is getting worse. More than 100,000 new cases have been reported each day for the most part of the past two weeks.

Is the worst of the pandemic behind us? Here’s what scientists know | Devi Sridhar

A second wave of coronavirus cases would be disastrous – but there are ways to prevent this happening

Over the weekend, there were no new deaths from coronavirus in London, Scotland or Northern Ireland. Slowly, the number of hospitalisations and deaths is falling across the UK. Rather than celebrating these early signs that the worst of the pandemic could be behind us, however, some scientists are warning of a second wave of infections – an increase in coronavirus cases in the coming weeks or months, which could occur even after a sustained fall in the number of cases. 

These warnings often refer back to the 1918 flu pandemic. That outbreak killed tens of millions of people when it returned the following winter in a deadlier form after the first outbreak had been controlled. But there’s a confusing lack of consensus from scientists about whether we’ll see a second wave of coronavirus cases. Although the future is uncertain, we can imagine four scenarios for what might come next.

Surgisphere: mass audit of papers linked to firm behind hydroxychloroquine Lancet study scandal

Questions continue for Surgisphere and CEO Sapan Desai as universities deny knowledge of links to firm behind Lancet’s now-disputed blockbuster study

Dozens of scientific papers co-authored by the chief executive of the US tech company behind the Lancet hydroxychloroquine study scandal are now being audited, including one that a scientific integrity expert claims contains images that appear to have been digitally manipulated.

The audit follows a Guardian investigation that found the company, Surgisphere, used suspect data in major scientific studies that were published and then retracted by world-leading medical journals, including the Lancet and the New England Journal of Medicine.

Brazil stops releasing Covid-19 death toll and wipes data from official site

Government accused of totalitarianism and censorship after Bolsonaro orders end to publication of numbers

The Brazilian government has been accused of totalitarianism and censorship after it stopped releasing its total numbers of Covid-19 cases and deaths and wiped an official site clean of swaths of data.

Health ministry insiders told local media the move was ordered by far-right president, Jair Bolsonaro, himself – and was met with widespread outrage in Brazil, one of the world’s worst-hit Covid-19 hotspots, with more deaths than Italy and more cases than Russia and the UK.

WHO advises public to wear face masks when unable to distance

Over-60s should use medical-grade masks and all others three-layer fabric ones, health body says

People over 60 or with health issues should wear a medical-grade mask when they are out and cannot socially distance, according to new guidance from the World Health Organization, while all others should wear a three-layer fabric mask.

The announcement on Friday marks a significant change of stance by the WHO, which until now has been reluctant to advocate the wearing of masks by the public because of limited evidence that they offer protection.
