Why are masks standard PPE in an OR? And has been for easily 75 years.
Not sure what info you have, but masks certainly help to keep air droplets from hoing airborne. Be it from just breathing, or sneezing and coughing.
I'm not here to fight about weather masks arw worth a hoot or not, the posted evidence fed to us by the government is overwhelming that they dont help near as much as they thought. Right wrong or indifferent. And the dr mask thing is an irrelevant remark. Different masks from what 95% of the population is wearing. Again idc if you wear one it not, I was stating what information the cdc released.A mask isn't so much protecting YOU from the virus, but protecting you from getting your spit on others.
Less spit in the air means less spread of the Corona.
