      Also, none of the staff were infected—only people who were in direct line of the A/C for 53 or 73 minutes. (Hong Kong health authorities, who are excellent at evaluating this risk, consider more than 15 minutes at less than 6 feet as "close contact").pic.twitter.com/ZLItyBRqPw

      Also this is another example for the importance of masks for source control (asymptomatic spread plus droplets). Many still don't understand this crucial distinction: masks to *prevent* transmission. (Working on article right now!)https://twitter.com/zeynep/status/1251171855286906880 …

      Example of how the purpose of masks for ordinary people is still not understood. The ones with exhalation valves, including N95s, should not be worn around people, period. Not just in sterile hospital operating rooms as NYT claims. Cotton mask>valved N95. https://www.nytimes.com/interactive/2020/health/coronavirus-best-face-masks.html …

          It's easy to put a filter on the exhaustion valve. Though I guess many don't realize that this is an issue.

          What do the dashed arrows mean? Do they indicate that the exhaust fan pushed air back towards C? Or do they indicate that the presence of the wall pushed the air back towards C?

          also illustrates the impossibility if reopening restaurants. You can’t eat and keep your face covered

          Hard to see how these families would be able to eat lunch without removing their masks at some point. Makes a strong case for closing the dining area of restaurants, though. Takeout would be fine.

          People are not going to wear masks in restaurants. Maybe what the diagram proves is restaurants will be going out of business.

          I don't agree about the N95s. Not everyone has or wears a surgical mask. Once they have them, yes I will agree. But we are not there, and some people refuse to wear masks alltogether.

          The N95 mask with valve should only be worn with a surgical mask underneath.
