The primary role of basic face masks in the medical field (and clean rooms) isn't so much to keep stuff out to protect yourself as it is to keep stuff IN to keep you from contaminating everything else in your vicinity. Also reduces the amount of your face that is touchable so you aren't as likely to make that mistake.So are the face masks necessary?
I've heard up to 3B will be needed in the US, alone.One million masks down, 499M more to go based on estimates I heard a few days ago.
You don't need a mask, if you follow the advice of distancing, hand-washing, and not face-touching.I don't really understand this whole face mask situation.
The medical authorities say they are totally useless and us unwashed masses shouldn't buy/wear them because they are a super valuable resource that needs to be readily available. So which is it? Why do doctors want them so badly if they don't do anything?
For the general public, the main group who should wear masks are people who are definitely or potentially infected. In this population, the mask can reduce their chance of infecting others.So are the face masks necessary?
It's a matter of degree. So, for a sick person, even reducing the amount of virus they spread can lower the chance of infecting someone else. In that sense, the mask doesn't have to be 100%, in order to be helpful.People keep saying its for sick people, but if they can't stop a virus from passing through then what do they do?
I think with proper precautions most health workers will not get the virus.The sad truth is that it's assumed that all medical personnel will eventually contract the disease, so masks reduce the number of people they may infect before becoming symptomatic.
