Trying to capture recent articles on a few keys for #COVID19 spreading. Beginning of March, based on multiple cluster incidents, the medical expert panel for Japanese government identified three conditions for high transmission risk: (cont.)
1. Closed spaces with poor ventilation
2. Crowded spaces
3. Close-contact settings with conversations
Overlapping of three conditions are considered dangerous, and government and local officials have repeatedly instructed people to avoid these “three Cs”. https://twitter.com/jpn_pmo/status/1244231002257383424">https://twitter.com/jpn_pmo/s...

Wikipedia has a good summary on Japan’s contact tracing effort.

This theory could explain why jam-packed commuter trains in Japan are, surprisingly, not a significant source of massive transmission. Because people remain silent (loud talking on a commuter train is a taboo in Japan), and the car is often ventilated well at every station.
I& #39;ve just learned that "three Cs" is also used in Malaysia. I wonder if other East/South East Asian countries have similar notion to emphasize high-risk situation for COVID-19 transmission. https://www.malaymail.com/news/malaysia/2020/04/15/social-distancing-avoiding-three-cs-more-important-than-face-mask-heal/1857028">https://www.malaymail.com/news/mala...
However, similar warnings have not been apparent in US media until recently. If we all keep 6ft/2m distance but keep talking in a poor-ventilated indoor space, is it still really safe?
Recently I’ve seen a couple of articles talking about observations similar to “three C” conditions.

BTW I was so glad to see this article that I instantly tweeted about it, because it pointed out the same concepts as “three Cs”. https://twitter.com/fujita_d_h/status/1259223601477279748">https://twitter.com/fujita_d_...
Article from @Bloomberg summarizing @ErinBromage’s blog (wow his blog got 11M views!) https://www.bloomberg.com/opinion/articles/2020-05-15/will-i-get-coronavirus-at-the-grocery-store-unlikely">https://www.bloomberg.com/opinion/a...
Another famous thread from @DKThomp
> talking, laughing, singing in close quarters, in unventilated interiors, for many hours, is the perfect storm for a COVID super-spreader event. https://twitter.com/DKThomp/status/1260305939153985536?s=20">https://twitter.com/DKThomp/s...

@pete_wells / @NYTimes reports that just talking, not coughing or sneezing, is enough to emit droplets into the air which might contain viruses. https://twitter.com/pete_wells/status/1261140258768461831?s=20">https://twitter.com/pete_well...
With US and European countries heading toward reopening the economy, it is even more important that people understand the high-risk situations and avoid them. Hopefully this recent trend will positively impact people’s behavior going forward.
Just learned that NYC city council is now also aware of three Cs. https://twitter.com/MarkLevineNYC/status/1263479975157673985?s=19">https://twitter.com/MarkLevin...
And here& #39;s the recently-circulating Bloomberg @business & #39;s article which mentions three C& #39;s explicitly. https://twitter.com/GearoidReidy/status/1264038262273748993?s=20">https://twitter.com/GearoidRe...
Also just learned that a cell biologist @RockefellerUniv tweeted very comprehensively on how Japan has been tackling #COVID19, including three Cs, on Mar 20-ish -- 2 months ago!. If I knew this thread I would not have started this thread.
