There were many people that were cured from the virus,but got infected again.
This is very interesting. Is this valid information? Could you please provide the information source?
I also don't know about this, but I also read that it's not about reinfection but its because the patient hasn't even recovered yet. And for test accuracy problem, is it because of a human error, no?
So for OP, this idea is not possible to happen in the near future because even from the medical side there are still many problems and not to mention the other things that have been mentioned before.
But that's very creative thinking tho.
