Coronavirus Positive but not Contagious
Testing Positive a Second Time
People who test positive after they have already recovered from covid-19 may not be contagious.
That’s according to a study by South Korea’s Center for Disease Control.
Researchers looked at 285 people who tested negative after recovering from the virus.
But later on, they tested positive a second time.
They tracked 790 of their close contacts and did not find any new positive cases.
Also virus samples reportedly collected from the patients could not be grown in a culture, which the experts believe means they were shedding dead virus particles.
Now South Korean health officials say they will no longer recommend people test negative in order to return to work, if they have recovered and finished their 14 days of isolation.
