How do you know you are not sick? COVID could stay in your body for first few weeks & you wouldn’t know it. - Asymptomatic

at this point, it should be abundantly obvious that the point of mask-wearing is collective protection from asymptomatic people. You’re a bad person because you’re actively putting others in harm if you’re not wearing a mask in public, because there is a chance you’re an asymptomatic carrier.

You might not know if you are sick or not, though. There have been many asymptomatic cases.
