Common surgical masks block the droplets coming out of a person from getting into the air, but they are not tight enough to prevent what’s already in the air from getting in. N95 masks are not only pricy, they are difficult to use without training and must be fitted and tested to work properly.
Exam gloves can be helpful, but you must use them correctly because they can get contaminated just like your hands. It is important that anyone wearing a mask be treated with respect and not fear.
