People who refuse to wear masks in public places don’t get it...but they probably will eventually.
Risk of contracting the virus when casually spending a few minutes within 6’ of someone who is infectious without both wearing a mask is 17%. Wearing a mask drops that to 3%. If both wear masks, it drops to less than 1%.
Spend an hour without a mask with a person who is infectious and not wearing a mask and the risk rate is close to 80%.
