"...aerosols, I think, was another surprise. We thought we knew how respiratory viruses generally work. We thought it was going to be droplet, and it turns out, you know, a lot of aerosol." - Rochelle Walensky

[BOO]: Norovirus can spread via airborne routes too, but sure don't mention that and instead talk up droplets and dirty surfaces

[BOO]: Reading from from a teleprompter we're told it isn't primarily airborne, and that washing our hands will save us from infection (it won't)

[YAY]: @CDC's Mandy Cohen, talks up masks

[YAY]: Good job but a little late for Christmas

[BOO]: "You can go back to your normal activities if your symptoms are getting better overall (at least 24 hours) and you have not had a fever and are not using fever-reducing medication". At least the page talks up ventilation.

[YAY]: "Airborne" and "aerosol" are absent, but new CDC advice talks up fresh air ventilation and CO2 monitoring
