Researchers at Los Alamos National Laboratory are investigating the complex relationships between the spread of the HIV virus in a population (epidemiology) and the actual, rapid evolution of the ...

They found more than 400 different mutations in 139 genes that play a role in people's risk of catching viruses -- a finding that may also help explain why some people sail through flu season ...

Researchers around the world are trying to understand the virus’s evolution in more detail, and particularly how mutations in SARS-CoV-2 alter its ability to spread among humans. “A well-adapted virus ...

The sequence analysis identified 381 persistent infections with high viral load (Ct value of 30 or lower) lasting for at least 26 days. These infections were caused by alpha, delta, BA.1, and BA.2 ...

“When you have a pandemic or an epidemic at some point in evolution, the population that is targeted by the virus either adapt s, or goes extinct. We knew that, but what really surprised us is the ...

At the time, this was quite a novel idea. Flu and COVID evolution do differ in important ways, but chronic COVID infections, too, are now being examined as harbingers of the future.

A team of virologists, infectious disease specialists and pathobiologists affiliated with several institutions in China and the U.K. has found possible evidence that bird flu vaccinations are ...

Another possible source of variants could be through animal hosts. The virus that causes COVID-19 can infect several animal species, including mink, tigers, lions, cats and dogs.
