I guess I’m skeptical, isn’t the majority of covid spread through prolonged close contact? Running into a grocery store without a mask for fifteen minutes seems extremely low risk compared to other activities.
I recently got it via short contact (3 weeks ago, was positive until yesterday, still have a cough).
I went to an amusement park. None of the people I was hanging out with had it nor tested positive before or after (they were all testing regularly) so the only other explanations are random people I passed at the park, food that was contaminated, or random covid virus in the air.
Of course my getting it via short contact does not invalidate the idea that most of it is spread via prolonged contact. But, given I just caught it via short contact I'm not going to stop taking prevenative measures in situations with only short contacts.
