Nurses working in the ICU during the beginning of the pandemic would use the same mask for an entire week without losing efficacy. If the masks didn't work, we would have seen a huge number of them infected in the NYC hospitals but that didn't happen. Most viruses don't survive very long on surfaces.

ICU nurses wear N95 masks that are fitted and tested (a bad tasting/smelling aerosol is used). It is completely sealed around the face. This is how my SIL did COVID ICU for 1.5 years every week without contracting it. Not the same as the one size fits all n95 people loosely place on their faces.

Nurses in ICU are constantly sanitizing their hands, use gloves and are trained about the dangers of constantly touching your face.

Virus can last for days on glass, metals and other non porous surfaces.
