Several months ago #TheCoronavirusBook discussed the false dichotomy between droplet and aerosol transmission. “Some nuance can be lost in the oversimplified false dichotomy of airborne versus droplet transmission; they are not mutually exclusive.” 1/
“In 1934, W.F. Wells developed the Wells evaporation-falling curve of droplets and demonstrated that in the right conditions, some droplets would lose water to evaporation while falling, shrink in size to become droplet nuclei and float in the air.”

“Evaporation of droplet water might explain why COVID-19, which usually spreads by droplets, might under some circumstances spread via aerosol.” #TheCoronavirusBook 3/
“Aerosols may have played an important role in the Amoy Gardens SARS outbreak in 2003.” 4/ #TheCoronavirusBook

9/ Hand hygiene is great, it has a lot of benefits from an infection control POV but SARS-CoV-2 is a respiratory pathogen and it seems droplets and droplet nuclei are most important in transmission (droplets + short range aerosols) @mtosterholm @CIDRAP are doing great work!
@threader_app please compile this thread that explores the false dichotomy between droplet and aerosol transmission.
