"Of course we know it works for them"
How does this anti-logic make any sense? Do you think the masks have a sensor that turns off the "works" bit if it's on the face of a medical professional or not?
This is bit like demanding to see research that gravity has an impact on alpacas. We know fundamentally how gravity has an effect on mass, so it follows. Just as we know the fundamental filtering ability, and contagion spread limiting, of masks, including even surgical masks. We know that the CDC is telling health workers that don't have masks to even use a bandana wrap, as not only does it stop face contact it has some limited utility in stopping the tiny droplets of liquid that are one of SARS-CoV-2's vectors.
