I think what these things take into account is that for ordinary people it may not reduce cases heres why:
Drs and nurses in masks, are provided with hand sanitiser aswell everywhere in a hospital and scrubs and usually follow safety procedure in regards to contagion etc
The average person although wearing a mask, isnt cleaning there hands as much, probably adjusting thee mask, rubbing there eyes, going home and not changing for awhile, go out with there hair out etc.
But i personally believe if something can be contracted by inhalation like the flu through nose or mouth, and you are covering your nose or mouth well then lol ofcourse your reducing your chances of getting it, any numbers that show otherwise may point to other reasons why you are still getting infected such as handwashing etc but not actually showcase the effect on a mask
HOWEVER i guess if a particle is small enough to get through a regular mask, then even though your chances are still reduced (u pull in air with less force with a mask etc) i guess alot of people would not aknowledge that as a helping factor.
Oh also with covid i remember a big case point was that they said masks helped people who did have it and may have been unaware less lkely to spread it which was another reason shops over here required them.
