Face, sort of. The major vector of infection is getting virus into your noes/ mouth/ eyes etc, not really by touching your forehead. But instrumentally, I think full face is what makes sense here. Once you have touched your forehead, your face is not a clean zone anymore; when you go to bed and put your face on your pillow, you’ll (possibly) be transferring virus there. Likewise once you thoroughly wash your hands once home and let yourself rub your face, you could be recontaminating your hands and spreading the virus from your forehead to some mucus membranes. Even if this wasn’t the case, I think it is also easier to self control a “no-face” rule than make a judgement about exactly where your mucus membranes are every time you have a face itch (that itchy place near my eye is still skin, right?)
My first also implies avoiding touching your hair, but I haven’t followed up on this (I avoid it myself and think it would be prudent in general but don’t know what standard practice is among e.g. health care workers)
To clarify- is it face or mucous membranes? I’ve seen ‘face’ everywhere, and I can’t really understand how touching my forehead would infect. Thanks!
