Masks for doctors and nurses in hospitals is to prevent blood spills and other liquids or large enough stuff. Not viruses.
For example a dentist that wants to prevent having blood or saliva splashed in their face when operating.
I have an actual mask with an air filter for viruses. It costs a lot of money, it covers hermetically my whole face including eyes, and each filter only lasts for 30 minutes under viral environments.
In general the best you can get for virus protection is a pressure positive suit:

- frankreyes 3y agoYes, because saliva spills and "aerosol" are two different things... Aerosol is when water and liquid particles remains in suspension in the air, just like moisture, mist, a perfume or fragrance. And that's what spreads the virus. COVID transmission is with aerosol. Face masks, including those in hospitals, don't block aerosol
