Part of wearing a mask and eyewear is to remind you not to touch your face. Yeah - hard to do. (Just thinking about it - now I have to itch my nose!)
That’s exactly what happened to me :-)
I had no mask to ‘remind’ me; but you could easily come home, take your gear off, and touch your face before washing your hands. Many viruses can live a long time on surfaces, especially on human skin.
I think the frequent and vigorous hand washing/rubbing under running water is one of our best first defenses.
