These RN’s need to stay within their specialty. Purely political request.

They shoot themselves in the foot with their letter by first demanding a nationwide mask mandate, then demanding the CDC recognize that COVID is transmitted via aerosols (particles <5 µm).
Well....Masks prevent droplet transmission, not aerosol transmission (unless one is wearing an N-95 mask).
BTW......To date, every randomized clinical trial has shown that masks do not work. But 100’s of “science” articles using modelling studies (like climate change studies) shows how “wonderful” they are.
