Here is how long it is necessary to test positive for coronavirus after an exhibition
An infectious disease specialist explains why your coronavirus test results may not be accurate.
A recent report of the disease control and prevention centers (CDC) estimated that 40% of all coronavirus transmissions occur frompeople who do not show any symptoms. It's either because they are asymptomatic or because they are pre-symptomatic (which means that their symptoms have not yet surface). So, that begs some very complicated questions when it comes toCOVID-19 test: How do you knowWhen tested for coronavirus? And can you trust the results?

But, as Note Landon, even if the test returns negative, there is no reason not to continue to be careful because you could very well wear the virus.
