Thank you so much @nanmargaret for this link! There are several interesting studies included in the listing that I will be reading! I also live in Florida so I understand your concern with the level of infection and the lack of mitigation and respect. (I think Gainesville is also a college town which may compound the problem if the university is not requiring vaccination, testing or masks.). Do you feel safe to go out while wearing your mask or do you prefer to stay home to be safe? I find it difficult to decide how much risk I want to take by going out with my mask. Very few people are wearing masks indoors so my protection is not that good if only I am wearing the mask.
