A member asked:

My brother-in-law tested positive for omicron then recovered.my sister shared the same bed without mask but she showed no symptoms.she also tested several times and the results were negative all the time.why didnt she catch it?

A doctor has provided 1 answer

She may be one of the few that are naturally immune, developed immunity from past vaccine or had it without symptoms sometime in the remote past. There is also the possibility she had it but tested negative, all of which has been known to happen.
