I think I/we might have Coronavirus thread (release your isolation-frustration here)

Sorry. Virus RNA (its structural molecules) are detected by a method called PCR. But the fact that the virus building blocks are present doesn't automatically mean that there are actual viruses capable of infecting another person there. When they went through the diamond princess cruise ship they found virus RNA on surfaces in the ship's cabins almost a month after all the passengers had left, for instance.
