A surgical mask is only effective for, and intended to be changed, every 15 to 20 minutes in a surgical application and between every patient in a general nursing care application.
Effectiveness is also dependent on the mask being worn correctly at all times. One pull down or having your beak hanging over the top and you've defeated any possible purpose whatsoever.
The airborne virus can also enter your body through your eyes. Only goggles that seal to your face can prevent that, not glasses, not plexiglass partitions.
This is why medical personnel were so angry that they weren't being supplied adequate numbers and types of masks and ppe in general.
A properly fitted and properly worn N95 is the only mask available that can provide any semblance of reliable airborne virus protection when used as single patient/single use personal protective equipment.
During the pandemic you were required to wear the same N95 (when they finally became available) until it became either torn or visibly/heavily soiled - or two weeks, which ever came first. Later that was reduced to one week. You know, after China cranked out a several billion of them. Not too quality i assure you.
Few wore a mask properly.
No one wore a mask at home.
If they believed it prevented spread I have to wonder what magical thing they thought occurred once they entered their homes.
Either the virus was fought off very early by your immune system, you were infected but not symptomatic, or you are immune to the virus.
Masks only offered a false sense of security.
