With three coronavirus epidemics or pandemics already in the 21st century alone, it’s fair to say coronaviruses are right up there with flu as having dangerous pandemic potential. Dr Melanie Saville Executive Director of Vaccine Research and Development, CEPI
The Food and Drug Administration now recommends that people who have been exposed to the coronavirus should have three negative at-home tests, even if they don’t have symptoms. The FDA made the change Thursday based on evidence that people with an omicron infection — but who are asymptomatic — need multiple negative rapid antigen tests over a number of days to be sure they don’t have Covid. Rapid at-home tests are more likely to give a false negative result in asymptomatic cases.
