SARS-CoV-2 is upping its game, we should up our public health response too
I’m getting a lot of questions about the new variants of SARS-CoV-2 coronavirus, the virus causing COVID-19, and thought I’d summarize what we know so far and what we can do about it. While viruses and bacteria undergo mutations all the time, many of them do not affect how infectious the virus is or the course of illness. SARS-CoV-2, like other coronaviruses, is generally slow to mutate thanks to built-in error-correcting proteins that fix most mistakes in replication. It generally accumulates one or two mutations per month. However, the number of mutations in the important “spike protein” that plays a key role in infection and is the target for most COVID-19 vaccines, as well as the association with a rapid rise of cases in these locations, has raised concerns.In rec...
