Testing healthcare workers can play a role in preventing new infections, but is a highly limited strategy and shouldn’t distract from other, more helpful measures.
It’s nearly impossible to avoid close contact when protesting, and easy to forget the risks. An infectious disease expert answers key questions about how to avoid spreading the coronavirus to family.
An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
Early reports by the National Health Laboratory Service indicated that it had the capacity to do 30,000 tests a day. But capability to do so has not materialised.
