The rapid evolutionary dynamics of RNA viruses, driven by high mutation rates and the consequent formation of complex quasispecies populations ...

Scientists in Switzerland have cracked open a century-old viral mystery by decoding the genome of the 1918 influenza virus from a preserved Zurich patient. This ancient RNA revealed that the virus had ...

The SARS-CoV-2 virus that causes COVID has the unsettling ability of often generating variants of itself. Other viruses also mutate, but as SARS-CoV-2 quickly spread throughout the entire human ...

Have you ever wondered why you have to get a flu shot every year, but some vaccines are one-and-done? It all has to do with how and how fast viruses evolve - and that depends on mutation rates.

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense ...

Viruses are everywhere. They’re in the air; in sewage, lakes, and oceans; in grasslands and decaying wood. Some thrive in extreme conditions, like hydrothermal vents, Antarctic ice, and potentially ...

A 13-year-old girl in British Columbia who was hospitalized with bird flu for several weeks late last year harbored a mutated version of the virus, according to a report published this week in the New ...
