Once to prove they have COVID-19.
Two or three times to prove they have cleared the virus (not shedding the virus)?
Then if they are still contagious how often are they tested?
What percentage are ongoing carriers? If someone is a carrier what do we do with them?
What if the current test only screens for one mutation of the virus? Is it the mild version or the deadly version? How many mutations are there? 8 or 9?
How many tests will we really need?
Lots of questions and few answers and resources.
Stay home as much as possible but know that it is likely that sometime you will get this virus and pass it along.
Stay safe, protect other people and be prepared as you can.
