The Coronavirus Chronicles -Three Strikes You're Out

[the Ferret]

The thing that confuses me about testing if you are not showing any symptoms is.. so you are not showing any symptoms, but you are over 65 (among the group they recommend testing). You go in and get tested and the test results come back negative. Great. A week or two later you go to the grocery, or hardware store and come in contact with someone who has the virus (the clerk?).... and become infected then. So how often do you need to get tested? I can't see this being a one and done deal. People that were among the first tested weeks ago could certainly be infected today. Right?
