With the studies shown today, it is rather stunning that CDC is going with the “no aerosol bro” party line.
It gets the conspiracy theory folks around here all revved up. ;-)
Despite their public "no aerosol" statements, they are recommending Airborne Infection Isolation Rooms (AIIR) for confirmed infections and Airborne Precautions for providers. These are single patient rooms with negative pressure and no exhaust without HEPA filtration. For medical purposes, Airborne is aerosol, while spray is droplets. Droplet protocols are significantly easier than airborne.
There are also studies for MERS and SARS that indicated aerosol transmission, so assuming aerosol transmission until proven otherwise just makes sense.
