      Yep, this actually makes a lot more sociological sense, and the experience of Hong Kong/Taiwan etc. support this: widespread mask wearing *signal* solidarity and importance/reminder of the pandemic, and probably encourage *more* distancing/hygiene as well.https://twitter.com/lydiajo/status/1252656232193720320 …

      Purely anecdotally, I don't feel 'safer' wearing a mask (even if I am), I feel more aware of the risks around me. The fact that wearing a mask isn't comfortable is a constant reminder that my environment is potentially hazardous. My mask reminds me that things are not normal.

      Another crucial study showing how dangerous indoor situations can be. An alarming 94 (out of 216) people on the same floor in a call center in Korea got infected—an attack rate of 43.5%! But look at the schema. Most infections are on one side of the room. https://wwwnc.cdc.gov/eid/article/26/8/20-1274_article …pic.twitter.com/JQsVnDGtA2

      Also only three people on other floors infected despite "frequent contact in the lobby or elevators" (but not a lot of travel between floors and no shared restaurant). Much lower transmission also later to household members (16.2% attack rate). High risk for crowded indoors+time.pic.twitter.com/Jqbdnmrd78

      Since people are looking at these studies today, I'm going put this paper here again (I'm a co-author). These studies increase the potential value of universal masking—especially indoors.https://twitter.com/zeynep/status/1249805628240953346 …

      I'm a co-author (one among many) on this new paper reviewing and synthesizing the strong scientific evidence for how universal masking can reduce transmission (source control) and greatly dampen the spread of COVID-19. It's under review. Preprint here: https://www.preprints.org/manuscript/202004.0203/v1 … pic.twitter.com/Q6CFBfUNgc

      Much of the confusion about masks is because people conflate preventing infection (PPE for hospitals) with stopping transmission (cloth masks for all).

      Another fascinating study. (Caution: preprint). There was one asymptomatic case in the second of two buses (59 and 67 passengers) to an outdoor worship event. Infections in bus one: zero; bus two: 23. Seven close contacts out of 172 at event also infected. https://www.researchgate.net/publication/340418430_Airborne_transmission_of_COVID-19_epidemiologic_evidence_from_two_outbreak_investigations/link/5e87b59ba6fdcca789f10d66/download …pic.twitter.com/wtYbQyM3s1

      This doesn't rule out other methods but seems clear that sharing an air pocket with a large number of people at length (the bus ride was 100 minutes) in a poorly-ventilated, indoors environment where people talk is a significant risk. The superspreader is the person and the room.

      Not necessarily. Taiwan and Hong Kong have their very dense and heavily-used public transportation systems open (never closed them) and they are registering zero cases per day now. But everyone wears masks on public transit. https://twitter.com/slaughterdotcom/status/1255614534846500865 …

      So where is our contact tracing study for meatpacking plants? Is it the workplace or crowded living conditions of vulnerable workers like in Singapore? Both? We don’t have factory outbreaks reported elsewhere so what’s different? (Need data, not guesses).https://twitter.com/crampell/status/1256052475020312576 …
