@MrMaxPowers247 of course its to prevent droplets from going into an open wound... which is how airborn viruses and bacteria spread... you really are a bit behind the 8 ball huh? Also its hardly limited to surgeons, nurses and doctors wear them regularly in nonsurgical settings to prevent infection as well.. because as you just pointed out, droplets are how infections spread.
Try linking the peer reviewed study and not just screen shot from god knows where. Oh wait, that would mean we might see the bullshit, cant have that.
