There is no way to get it from nowhere... That’s not possible.
In Canada they reported on a couple who had the new strain of the virus and the initial story indicated that they didn’t have any contacts from England and that they got the virus without any contacts with anybody who was sick... Scary stuff... Except a few days later the couple fessed up that they did indeed have contacts from England and apparently, that’s where they got it... People lie when people are embarrassed, and getting infected has a stigma. That’s why contact tracing is so difficult. People do not want to contact their relatives and friends and say... Hey... I’ve got covid and you may get it too... So they lie.
I believe it lingers in the stores and we're touching it...then we take our masks off...or play with it while we're in the store...
and we're physically carrying it with us allotting enough time to infect ourselves.
Fauci even said forget about sanitizing your home...just wash your hands.
