common, as much as I may be guilty of inappropriate language, I don’t think I am in this case. Mazik means “someone who damages”. That is, you were presenting a danger to surrounding people. It describes technically what I think your halachik category was.
Now, you can argue to what degree a mazik, and that is fine. This is a difficult statistical question that depends on both the mazik and the nizak. If you were hanging around your closely-spaced unmasked kehilla, then you can argue that you are not presenting any additional danger to anyone. But if a person you met was sitting at home, following Bava Kama and CDC, and ventured to buy food for shabbos, then you represent 100% of his danger.
