British researchers believe they have documented the longest-known Covid-19 infection, in a patient who tested positive for a total of 505 days before their death. The previous record for persistent infection -- rather than repeated bouts of Covid -- is thought to be 335 days, the team from King's College London and Guy's and St Thomas' NHS Foundation Trust said.

Virologists have identified 5,504 new virus species floating in ocean water samples. The viruses were found using a machine learning algorithm to study 35,000 water samples from all over the globe, reports Vishwam Sankaran for the Independent.

The findings add further weight to the idea of mix-and-match boosting.

A new technology aims to stop wildlife from spreading Ebola, rabies, and other viruses. It could prevent the next pandemic by stopping pathogens from jumping from animals to people.

Phase 1 study is among first to examine mRNA technology for HIV.

One of the four flu strains -- B/Yamagata -- included in annual flu shots appears to have fallen off the radar.

Genomic surveillance of SARS-CoV-2 is helping us spot new variants and figure out how to respond. What else could it help us do?

The global pandemic sparked a huge superhuman effort to control coronavirus. But the billions spent have also had an unexpected impact on medicine and science

By month 25 of the Covid-19 pandemic, we all probably should have learned not to try to anticipate what the SARS-CoV-2 virus is going to do next. It has so consistently defied predictions.

Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne – with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus survives in exhaled air suggest. The findings re-emphasise the importance of short-range Covid transmission, with physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact.

The rapid accumulation of mutations in the SARS-CoV-2 Omicron variant that enabled its outbreak raises questions as to whether its proximal origin occurred in humans or another mammalian host. Here, we identified 45 point mutations that Omicron acquired ...

In late November, more than 110 people gathered at a crowded Christmas party at a restaurant in Oslo, Norway. Most of the guests were fully vaccinated. One had returned from South Africa just a few days earlier and was unknowingly carrying the omicron variant of SARS-CoV-2.

Now that mRNA vaccines have proved effective against the coronavirus, scientists are taking aim at influenza, HIV and other viruses.

The World Health Organization urges people to be cautious and prepare for the Omicron variant.

‘If we could see eating meat as a treat, not a right, we could reduce the speed at which another virus evolves,’ says professor

The first South African doctor to alert the authorities about patients with the Omicron variant says the symptoms differed from previous Covid patients.

A plant-based antiviral treatment for Covid-19, recently discovered by scientists at the University of Nottingham, has been found to be just as effective at treating all variants of the virus SARS-CoV-2, even the highly infectious Delta variant.

The Centers for Disease Control and Prevention said it was working with law enforcement to investigate the vials.

A woman in Argentina has become only the second documented person whose own immune system may have cured her of HIV. Researchers have dubbed the 30-year-old mother, who was first diagnosed with HIV in 2013, the “Esperanza patient,” after the town in Argentina where she lives. In English, “esperanza” means “hope.”
