It's quite weird having had COVID and not sure what the position is now. Could I be a carrier and pass covid on from a person(for example one of my kids' classmates) to another person (for example the grandparents). Do I need to wear a mask/sanitise to the park extent I was before? Can I hang around covid people (for instance my kids if they get it) without catching it again for next 90 days? Help, I'm being thick!
