I have a question but i'm not sure what the answer is and other than Dr. Gupta or Dr. Fauci i'm not sure who'll be able to answer it:
Let's say someone tests positive for coronavirus but doesn't have any symptoms. He's told to go into quarantine, correct? But what if nothing changes after 15 days and he still feels good. Do they keep testing him & send him into quarantine if he's still testing positive? I see no reason why the virus would be gone since all it needs is a warm body to survive & because someone has no symptoms doesn't mean that the virus cannot survive in that body forever, right?
In short, the answer is yes, remain in quarantine, since this is what is being asked of all non-essential people anyway. As an asymptomatic, covid positive individual, it is even more important to be isolated since this group
are likely to be high infectors.
Also, it was recently reported that the 15 day window to developing symptoms may be longer and that 21 days may become the more appropriate incubation period. Regardless, The testing we have today detects the presence of the virus. It is a yes/no type of result. If the result is positive, that means the person still has virus circulating (blood/mucosa etc)and is therefore still infectious.
The body's own immune system can (and does) rid itself of the virus. It does not reside forever. That is when a patient will re-test negative. That is also when a serology test will confirm presence of antibodies to the virus. It is presumed (by Fauci and many others) that immunity against COVId can be achieved by the body's natural immunity. We have not seen studies yet to confirm.
