I’ve been wearing masks into the rooms of influenza patients’ rooms for over 20 years. Are they perfect? No. Do they make a difference? Yes? Does everyone taking any med get a benefit? No. NNT. If you are an MD you know this. We asked 18 year old kids to go to France and save the world 70 years ago. We can’t ask people to wear a mask in a grocery store during the height of a pandemic
to protect the vulnerable? We are a county of dbags.
