Covid-19 patients are no longer infectious after 11 days of getting sick even though some may still test positive, according to a new study by infectious disease experts in Singapore.

A positive test “does not equate to infectiousness or viable virus,” a joint research paper by Singapore’s National Centre for Infectious Diseases and the Academy of Medicine, Singapore said. The virus “could not be isolated or cultured after day 11 of illness.”

The paper was based on a study of 73 patents in the city-state.

1. Thanks. But I'd place this on hold

2. I'm not sure infectiousness is based on testing positive.

Aren't there also people testing positive after recovery that they are saying appear not to be contagious?

If a positive test does not necessarily mean contagious, what reason is there to believe that a negative test means NOT contagioius?

This virus seems to defy a lot of standard medical assumptions.
