>The CDC maintains that "respiratory fluids" - droplets - are the "principal mode" of transmission, distinguishing them from "aerosol particles formed when these fine droplets rapidly dry." CIDRAP research consultant Lisa Brosseau faulted the agency for "underplay[ing]" the science of aerosol transmission "despite so much evidence to the contrary." And when these droplets land on a cloth mask and then dry out, they become aerosolized and get spread all over the place through further breathing. The very thing supposed to prevent covid spread is contributing to its transmission.
