Hopes for a promising COVID-19 treatment suffered a setback yesterday after WHO inadvertently published a summary of a remdesivir clinical trial on its website, STAT reports.

The summary, which has since been removed, showed the drug "failed to speed the improvement of patients with Covid-19 or prevent them from dying," according to STAT.

How the coronavirus is affecting the world

covid-19 pandemic

Dealing with the unforeseen challenges caused by the COVID-19 pandemic has taken a significant toll on people all across the world. Medical News Today has spoken with people from different countries, asking how the pandemic has impacted their lives.

At the time of writing this Special Feature, there are over 2,700,000 confirmed cases of COVID-19 across the globe.

According to official reports, the largest numbers of confirmed cases are in the United States, Italy, Spain, and France. However, even the countries that the new coronavirus has hit less aggressively are still under considerable strain.

Coronavirus drifts through the air in microscopic droplets – here’s the science of infectious aerosols

Pflugge droplets

During the 1970s when I was growing up in Southern California, the air was so polluted that I was regularly sent home from high school to “shelter in place.” There might not seem to be much in common between staying home due to air pollution and staying home to fight the coronavirus pandemic, but fundamentally, both have a lot to do with aerosols.

Aerosols are the tiny floating pieces of pollution that make up Los Angeles’ famous smog, the dust particles you see floating in a ray of sunshine and also the small droplets of liquid that escape your mouth when you talk, cough or breathe. These small pieces of floating liquids can contain pieces of the coronavirus and can be major contributor to its spread.

Protective masks can be effectively disinfected at home, study finds

Disinfecting masks

Researchers conclude that homemade masks and some medical masks can withstand simple disinfection without significantly reducing their effectiveness.

A new study has found that disinfecting homemade masks by heating them may not significantly reduce their effectiveness — and that some medical masks can undergo this process and still be effective.

The research, published in the Journal of the International Society for Respiratory Protection, may be valuable for reducing the pressure on stocks of medical masks during the coronavirus disease 19 (COVID-19) pandemic.

A french study finds that nicotine protects from COVID-19 disease

Nicotine patch

Does Nicotine Protect Against Covid? This is the very serious hypothesis of a Pitié-Salpêtrière team and a world renowned neurobiologist. It should soon be the subject of a clinical study: nicotinic patches will be administered to patients and caregivers to measure the effects.

Nicotine, a preventive and curative remedy against Covid, is therefore the hypothesis defended by an internal medicine team from the Pitié Salpétrière hospital, and a world-renowned neurobiologist, member of the Academy of Sciences, Jean-Pierre Changeux.

Bat survey identifies six new coronaviruses

Bats flying

Scientists have discovered six previously unknown coronaviruses in bats. The animals were in regions of Myanmar where humans come into close contact with wildlife as a result of agriculture, deforestation, and other ecological disruption.

Wild bats are generally beneficial for people living in many areas around the world. They pollinate crops, control pest insects, and produce guano, which farmers collect from caves to use as fertilizer.

Many experts think that these mammals were the original hosts of several viruses that pose a significant threat to human health.

It’s time for us all to fund the World Health Organization

Finland’s foreign minister Pekka Haavisto

World leaders have reacted with shock and dismay to President Trump’s recent decision to suspend US public funding to the World Health Organization (WHO).

His move cuts off oxygen to the nerve centre of the global coronavirus response, just as more and more countries are counting on it. With voter approval droppingand US cases by far the highest worldwide, observers have seen a scapegoat in Trump’s decision. The move is also unjustified by the facts. What needs to be done now?

Hydroxychloroquine is not such a good idea

Hydroxychloroquine as treatment for COVID-19

Humans have trouble grasping an essential fact about COVID-19: Nothing will be easy.

Once hailed as a wonder treatment, the antimalarial hydroxychloroquine is starting to look like not such a good idea.

New but not yet peer-reviewed research among 368 patients found the drug didn’t help patients and more patients who received it died than those who had standard care, AP reports.

Conspiracy theorists are falsely claiming that the coronavirus pandemic is an elaborate hoax

Limit the spread of the novel coronavirus COVID-19

In the midst of a global pandemic, conspiracy theorists have found yet another way to spread dangerous disinformation and misinformation about COVID-19, sowing seeds of doubts about its severity and denying the very existence of the pandemic.

Since March 28, conspiracy theorists — "coronavirus deniers" — have been using the hashtag #FilmYourHospital to encourage people to visit local hospitals to take pictures and videos to prove that the COVID-19 pandemic is an elaborate hoax.

SARS-CoV-2 may affect more children than scientists initially thought


Researchers have estimated that the number of children in the United States who spent time in a hospital with COVID-19 is likely higher than officials had previously thought. And the projected numbers of severe cases in children may overtax the health system, they warn.

According to a study paper newly published in the Journal of Public Health Management & Practice, officials may have been underestimating the impact of SARS-CoV-2 on children.
