‘I’m not convinced I can’t infect someone walking by’
really...? to give someone a simple head cold, you must breathe on them; how many people obviously suffering from colds do you think have walked by you in your life and not infected you...?
I don’t seem to come down with anything in the flu seasons.
You should ask someone else.
A lot of people do get sick. Is there a way to tell if
they got sick from breathing in someone else’s exhale?
