We've summarized the literature supporting airborne transmission of COVID-19 & several other respiratory pathogens. Guess what? #COVIDisAirborne #FluisAirborne #SARSisAirborne #MERSisAirborne

H/T to @rdumont99 for organizing and encouraging this collaborative effort to get the table updated and released
Required review readings:
science.org/doi/10.1126/sc…
nature.com/articles/s4157…
Several interesting observations when reviewing these pubs- will add to thread later

Small correction to page 2 of table, I made the evidence for TB look too good:

"its droplet spread because most transmission occurs at close contact"
Kenyon 1996 NEJM - TB on a flight:
"Passengers seated w/in 2 rows of the index pt were more likely to have + tb skin tests than those in the rest of the section (4/13, or 30.8%, vs. 2/55, or 3.6 %"

Olsen 2003 NEJM - SARS on a flight:
1 flight carrying symptomatic SARS+ passenger
22/119 passengers caught SARS, increased risk if sitting in the 3 rows in front of the index case
Another flight carrying 4 symptomatic persons resulted in transmission to at most 1 other person

"If it were airborne, we would see huge outbreaks with more patients and staff catching COVID on the wards"
Anderson 1985 Infect Control - Chickenpox at BC Children's Hospital
2 pts with chickenpox lead to 7 nosocomial infections (out of 41 susceptible patients).

Keep in mind, there was no universal masking policy at BC Children's in 1985. 17% attack rate doesn't sound too airborne by today's standards...
When they started using negative pressure isolation rooms for + cases, their nosocomial infection rate was 0/110 over 1 year
