Source for any scientific study that actually shows this
You can only spread virus for a certain number of days (10 seems to be the lucky number)
Simply being sick with Covid for a long period of time (those with immune system deficiencies) does not make them more likely to spread the virus
The larger issue is many of the "infected" people are not really infected; the tests are finding trace amounts of virus long after a person has recovered
The asymptomatic spread bullshit is to further the narrative
It really is an "I don't know" from Public Health who has been unable to trace the virus adequately
