Oh shit, the result of your PCR test is positive! Because they test 10 people with one test tube, now they need to find out who exactly is the one who got the big C. So you and the other 9 guy/gal/whatever went to do a PCR test again, this time separately; but alas, because you did your PCR test near these 9 potential virus host, you're now considered dangerous no matter what, so it doesn't really matter.
Fuck this I'm leaving.
