Masks reduce risk.
> [2] Doctors and nurses need that mask.
Here's the reason, right here.
Seems like we didn't prepare. There should be enough masks for healthcare professionals and ordinary citizens.
Wearing a mask, if the entire population is infected, provides a benefit because you are surrounded by infection. Guess which person spends 8 hours a day in a highly infected population? Doctors, especially in the intensive care unit.
If you were worth as much to humanity as a doctor, as an ordinary person, your logic would save fewer lives. However it would increase your chance of being saved.
Stop lying to people that masks aren't effective. Not only does that put people in immediate danger, it makes it more difficult to walk back that advice in a few months, when we're definitely going to want everyone to wear masks when in public.
Doctors and nurses need that mask
So make your own. Even half of a t-shirt is much better than nothing.
However we didnt, so stop promoting ordinary people wearing masks.
[1] Masks protect other people from you spreading the disease if _you_ are sick. This is true, unless you spend your day around covid-19 infected individuals all day long for your job. [2] Doctors and nurses need that mask. They are the ones who spend their day, risking their lives and their families health to treat these people.
Even now the risk of contracting the virus, if you are following isolation protocols, is extremely low.
