Scientists have observed that 501Y.V2 has quickly become "dominant" among multiple variants that have been circulating in the South African population.
We've gone from a novel virus to several COVID-19 vaccines in less than a year. Here's what we've learned from earlier vaccines to allow this to happen.
COVID-19 has been found in pets, zoo animals and in a wild mink in Utah. Monitoring wildlife for COVID-19 is important for animals and humans, both of whom face risks from a jumping virus.
The new SARS-CoV-2 variant is already spreading in the US and could be dominant by March, the CDC warns. Here's what that means for the masks you choose and how you practice social distancing.
West Virginia's success holds some important lessons for other states and the rest of the COVID-19 vaccine rollout.

Analysis of smartphone data shows why countries need to coordinate border closures to stop the spread of the new variant.
So far, the only COVID-19 vaccines authorized for use need to be kept frozen. But there are many places in the world that can't support a cold supply chain.
Experts weigh in on whether they will sit and eat at a restaurant.
With vaccines forthcoming for most Americans, many groups, including expectant mothers, are wondering if the vaccine is safe for them and their babies. A physician-scientist explains.
It's the part of coronavirus that helps the virus get into your cells – and also the target of the leading vaccines.
A new strain of the SARS-CoV-2 virus that causes COVID-19 appears to be spreading fast in the UK. This probably isn't a big problem, but the data isn't in yet.
All your questions about the new coronavirus variant, answered by a microbial genomics researcher.
The coronavirus vaccine was developed faster than any vaccine in history. It took just 332 days from the first sequencing of the virus genome to the first vaccines given to the public.
The development of multiple vaccines against the virus that causes COVID-19 has been hailed as the breakthrough of 2020. But there were many more supporting discoveries that made this possible.
So, if you have ever tested positive, there is a chance you could contract the virus again. And you could infect other people. You should still take the necessary precautions.
