want to test just so that i know that i am not going to go out and infect somebody else if, after five days, i'm okay. do you think, sanjay, this decision was made because it's impossible for or really difficult to get a test? i have gone to cvs -- i don't know how many cvss i have gone looking for them. >> yeah sadly and the admiral and i have talked about this issue of testing. there are still not enough tests available so in some ways this is a form of triage. let me show you the guidelines just to be clear what they are now telling people who are testing positive for covid. stay -- stay home for at least five days. your isolation can end if symptoms are gone or resolving. wear a mask around others for five more days but the new things they added to that, again, as you mentioned. optional antigen test around day five and if positive, isolate for -- for a full-ten days. that -- that -- it may not be disincentivizing testing but it's not really incentivizing
