If someone regularly wears a high quality mask but frequently handles the mask improperly - i.e., grabbing the front of the
mask to pull it down in order to blow their nose, wipe their
face, etc. - how harmful is that? Are they still generally safe given that they’re wearing a highly protective mask? Does repeatedly handling the “contaminated” part of the mask practically negate the purpose of wearing one? What if the person touches the mask with one hand and blows their nose with the other?
