But, that is the problem. You can't protect yourself sufficiently. It helps that you are wearing a mask and attempting social distancing. But, if others are not, your risk increases and there is nothing you can do about it if you are present. This is the whole issue underlying the anti-masker debate which is OT to this thread. It's not just about advising people to take precautions to protect themselves, it is about everybody taking precautions to protect everybody.
