Re: Covid cases are up

that's less than 1 person out of 100 that can give it to you indoors without a mask.

The aerosol can remain suspended in the air for 9 hours. One can get infected with 15 minutes exposure, even if those 15 minutes are not consecutive.

Suppose 100 people were in that room during a 9 hour period. The probability of at least one infected person is 63% (1 - 0.99^100).

It's a reasonable assumption that Covid is present in every indoor venue that's open to the general public.
