Also this comment (not mine) I quote from the original post on FB,
true or not??? hmm
"What is simple? Nobody is confused about the rules. What the post is concerned with,is that the virus has a 14 day incubation period. The government conveniently choose to test people on the 12th day instead of the 14th or 15th day,and therefore catch one or two cases on the 19th day that became positive on the 13 th or 14th day,or cases that had false negatives when tested on the 12th day,or were actually infected during quarantine. The maximum incubation period for this virus is 14 days and there has been no scientific evidence after 130million cases that show it is longer.
Very far from simple."
