I cannot seem to find a case where someone in the world has has covid 19 twice
Forget what the boffins say - if nobody has had it twice since it started then that is a factual statement in itself
If this is the case then why do those that have had it need to socially distance

It hasn`t been around a year yet!
People get the common cold more than once, but not necessarily every few months when they are re-exposed to it.
Absence of evidence, is not evidence of absence. That is, lack of proof of re-infection, does not prove re-infection is impossible.
People who are asymptomatic can pass COVID 19.
Infection may be passed by inanimate objects. Even a person who may be immune can pass the virus.
