The droplets vs aerosol debate for COVID19 is heating up. WHO has revised it's aerosol evidence review here:
https://www.who.int/news-room/commentaries/detail/transmission-of-sars-cov-2-implications-for-infection-prevention-precautions Section on airborne transmission.
I'm trying to understand what experiments would need to be run to
- determine if aerosol (long time, long distance) is possible.
- determine the "prevalance" of aerosol transmission. Here, let's say "<6ft" vs >6ft" infection.
no studies have found viable virus in air samples.(29-36) Within samples where SARS-CoV-2 RNA was found, the quantity of RNA detected was in extremely low numbers in large volumes of air and one study that found SARS-CoV-2 RNA in air samples reported inability to identify viable virus.
[on superspreading events] However, the detailed investigations of these clusters suggest that droplet and fomite transmission could also explain human-to-human transmission within these clusters.
I'll provide my answer below, but I'll pick the best answer from someone else.
Why I ask
I'm trying to write some online risk tools and calculators. See http://tinyurl.com/covid3particles
