COVID Science & Variants

Researchers found that people with acute respiratory infections who tested negative for COVID-19 could still experience long-term symptoms including coughing, stomach pain and diarrhea.

Fungi such as Aspergillus are so common in our surroundings that we breathe in hundreds to thousands of spores every day.

XBB.1.5, a subvariant of omicron, is gaining ground in the US, but deaths can still be avoided.

Global infections fall for the 3rd consecutive week, dropping 21%; WHO estimates 99% of all cases are Omicron variant; number of deaths also fall for first time since January

Here’s everything we do.

A COVID vaccine developer, an Arctic voyager and a prime minister are some of the people behind the year’s big research stories.

The high-profile retractions of two COVID-19 studies stunned the scientific community earlier this year and prompted calls for reviews of how science is conducted, published, and acted upon. The warning signs had been there all along.

COVID-19 hospitalizations instead of case counts should determine our public health measures to fight the Omicron variant wave

Research into the disease has focused on plaques in the brain. But some scientists think viruses and bacteria play a role – and their work is gaining ground

“There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this

We’ve let the data slip away.

Omicron, the 13th named variant of the coronavirus, seems to have a remarkable capacity to evolve new tricks.

Specific mutations hide the COVID-causing variant from the immune system and give it a new route into more cells

The virus is now embedded in our world. But there are steps we can take to keep it at bay while we continue to live our lives, says Edinburgh University’s Prof Devi Sridhar

The SARS-CoV-2 Assessment of Viral Evolution (SAVE) programme provides a real-time risk assessment of SARS-CoV-2 variants with the potential to affect transmission, virulence and resistance to infection- and vaccine-induced immunity.

There are already 127 confirmed cases across almost half of the U.S. of a new Covid subvariant that's even more contagious than omicron.

Moderna Chief Medical Officer Paul Burton said Covid is entering an endemic phase in the Northern Hemisphere.

After two years of pandemic waves, we’re finally learning whether the disease has a predictable schedule.

The US, UK, and Canada have high rates of people unwilling to mask up or get a shot, perhaps because they don't believe COVID-19 will kill them. More 'collective' thinking helps in other countries.

Cases of COVID-19 are rising fast. Vaccine uptake has plateaued. The pandemic will be over one day—but the way there is different now.

While the latest research suggests that antibodies against Covid-19 could be lost in just three months, a new hope has appeared on the horizon: the enigmatic T cell.

Every idea needs a Medium

Under the threat of COVID-19, governments are taking drastic measures worldwide to break the chain of the virus’ transmission. You yourself are probably reading this at home under a national lockdown or by practicing social distancing, effective measures recommended by public health authorities.
