To answer El Kabong's question of "OK then so if a person got tested for COVID & didn't have COVID they could not wear a mask and everything would be ok or is the mask a mandatory thing because "you never know"?"

If they tested negative and didnt wear a mask after that DURING THIS PANDEMIC, they could easily become infected from others who are also not wearing masks. Also, just because they tested negative today doesnt mean they are out of the woods because they could have been infected yesterday or 72 hours ago and the incubation stage is happening inside them may take longer --- I dont think you test positive the moment the virus enters your mucous membrane. It has to incubate and reach a certain level in your body before it shows up --- in many people this could take 7 days. So testing negative today proves only that right at this moment you dont have any detectable virus. So yes, you could test the following day, or 2, 3, 4 , 5 days later as positive even if today you were negative.

True what you say about "you never know", but during a pandemic it is certainly highly likely as contagious as this shit is, for you to be infected without a mask.

I didnt even get into how you may test negative but a few days later be positive and asymptomatic, and if you dont wear a mask you can easily spread it to others.
