AEROSOL—Computer model of the Diamond Princess cruise

utbreak found that the virus spread most readily in microscopic droplets light enough to linger in the air—it was aerosol. This is now slam dunk for the coronavirus aerosol transmission. #covid19 https://www.nytimes.com/2020/07/30/health/diamond-princess-coronavirus-aerosol.html

Aboard the Diamond Princess, a Case Study in Aerosol Transmission

A computer model of the cruise-ship outbreak found that the virus spread most readily in microscopic droplets light enough to linger in the air.

2) “Earlier, after pressure from more than 200 scientists, WHO acknowledged that the virus could linger in the air indoors, potentially causing new infections.”

3) Pre-print, but shown to nearly a dozen experts in aerosols and infectious disease. The new findings, if confirmed, would have major implications for making indoor spaces safer and choosing among a panoply of personal protective gear.

4) “For example, ventilation systems that “turn over” or replace the air in a room or building as often as possible, preferably drawing on external air to do so. But good ventilation is not enough; the Diamond Princess was well ventilated and the air did not recirculate”

5) “So wearing good-quality masks — standard surgical masks, or cloth masks with

multiple layers rather than just one — will most likely be needed as well, even in well-ventilated spaces where people are keeping their distance.”

6) “The modeling adds a new dimension of support to an accumulating body of evidence implicating small, airborne droplets in multiple outbreaks, including at a restaurant, a choir in Washington State, as well as a recent study of 13 passengers evacuated from Diamond Princess.”

7) NYT OP-ED: Yes, the Coronavirus Is in the Air.

“As we cough, sneeze, talk, breathe, we release droplets (small particles) and aerosols (smaller particles) into the air. The transmission via aerosols matters much more than officially acknowledged”. https://www.nytimes.com/2020/07/30/opinion/coronavirus-aerosols.amp.html

Opinion | Yes, the Coronavirus Is in the Air

Transmission through aerosols matters — and probably a lot more than we’ve been able to prove yet.

8) “Current guidance holds, but should be augmented: reminder to also open windows and improve airflow indoors. And the quality of masks and their fit matters too.”

Thank you to Dr @linseymarr. And this also supports @ASlavitt push for premium masks for all. #COVID19

9) This also matches up with recent studies on AEROSOLs being infectious in the air. https://twitter.com/DrEricDing/status/1285465200502755328?s=20 https://twitter.com/drericding/status/1285465200502755328
