People can be reinfected 'they' say after the Patient would have already been infected and recovered.......well for what I've learned today the reinfected thing is a lot less of a worry than people should think.
Of course if you had strong symptoms for a couple of weeks and tested positive for COVID, got way better in time and later tested negative for COVID and later got obviously sick again and then also tested positive for COVID a second time.....well you either had a second infection you picked up some how some where from someone else.....or you had a relapse because your own infection resurfaced?....or you had your negative result via a test that was wrong - so you waxed and waned on your own but were in reality sick with COVID for longer than the generally stated 2 week or so time frame. And then of course there's the test-positive asymptomatic person who later might test either way (positive yet or negative and then positive again) some weeks later.....always remaining asymptomatic.
However there's another way to end up having others thinking you're infected a second time......and have no symptoms.......because you're not really COVID sick the second time.
I've talked with the people that make the Abbott test and then confirmed something from what came to me from another channel.
The Abbott test will say 'positive' if it finds the virus containing its entire mRNA strand in you.......however tests may also say 'positive' if a segment of the entire virus mRNA is manifest......a mere partial segment of the mRNA chain will not make you sick or anyone else sick or replicate. So if fragments remain after one was infected (be it sick or asymptomatic originally) some tests will argue you're infected again......when you're not infected at all a second time.
Lack of symptoms after having COVID symptoms (because you were actually infected) is no proof that viron fragments are not present in the Patient......so you got to know the ins and outs of what test is administered.
Worst part of this becomes perhaps some Government Official thinks that - we'll call 'em a "fragment Patient" - the fragment Patient must once again self-quarantine for 2 weeks when they really didn't need to.........so the "COVID cops" maybe end up even arresting the fragment Patient who refused to stay home for the 2 weeks.
