Comment by Maxime_Riche on [Coronavirus] Is it a good idea to meet people indoors if everyone's rapid antigen test came back negative? · 2021-03-25T09:07:20.922Z · EA · GW

Could the odds be dominated by the symptom starting during the meeting (or shortly before it)? For that to be clearly false, the antigen test should be effective before the person is contagious. If the test is taken 6h before the meeting then the test should be reliably effective 6h before being contagious.
