It's always hard to tell where you might have gotten something from. Especially with COVID restrictions in some places still. People still don't get out as much as we used to.

Here in GA a looooooot of people still don't wear masks. With no real restrictions you can't tell. Sure the rule is if you've been vaccinated you don't have to wear it now. Thing is even those not vaccinated aren't wearing. So you can never tell for sure.
