Wasn’t the goal not to prevent infection, but instead to reduce the spread of the disease? If I remember correctly hospitals were overburdened at the time.

Also no I (personally) have not seen anyone have any sores or issues with wearing a mask, medical professionals, students, or otherwise.

If the goal was to reduce the spread of the disease, then the mitigations in place need to be based on what will be effective against an airborne disease, not what will be effective against a disease with a droplet based spread.

We aren't talking about wearing a cloth mask, as those are ineffective. We're talking about wearing an n95 mask (or better), fitted tightly enough to your face to prevent unfiltered air from leaking in through the sides, and wearing it day after day. You end up with bruising and pressure sores.

For instance, here's the CDC guidence on how to know if your n95 mask is fitted properly.

> To conduct a negative pressure user seal check, cover the filter surface with your hands as much as possible and then inhale. The facepiece should collapse on your face and you should not feel air passing between your face and the facepiece

As far as Doctors and Nurses posting pictures of the results of properly wearing PPE day after day, they were all over the internet.
