There’s pretty much no one left in the US who hasn’t been exposed to the coronavirus, whether by vaccination, infection or both.

Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.

A team of researchers from Indiana University performed random testing for SARS-CoV-2 across the state. The results offer some of the most accurate data to date about important aspects of the virus.

An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.

Testing for coronavirus has been a fiasco in the US. But now companies are developing super fast tests, including ones that might eventually be as simple as at home pregnancy tests.
