      On my social feeds where many Taiwanese & HK-ers hang out, they‘ve been debating (or moaning) about just one main thing: what’s up w/ this contradicting groupthink in the west about masks? Both TW & HK have so far contained #covid19 w/ universal mask-wearing as a key component.https://twitter.com/zeynep/status/1239903421970501640 …

      For the @nytimes, I wrote about why health authorities telling people they didn't need masks, and, besides they wouldn't wear them right, misfired and maybe even fueled hoarding. There will be many painful truths, and we need to learn to talk about them. https://www.nytimes.com/2020/03/17/opinion/coronavirus-face-masks.html … pic.twitter.com/vBhEbS2rJk

      everyone was being told that only ppl who are sick should wear them – back when everyone thought you could only pass the virus along if you showed symptoms. I believed it until I realized...they're saying this bc there aren/t enough masks

      Given the shortage, I trust no1 would object to medics-first mask distribution. The point raised by @zeynep though is also on how govt’s comms affects public preparedness. In Jan, when HK govt plainly said they couldn’t source enough masks, people began sewing DIY reusable ones.

      That said, I have yet to come across empirical study into how DIY masks compare to the 3-layer surgical masks. Many are aware that the combined fabric must meet 95-99% filter efficiency to work, but the results could vary a lot. Since I haven’t seen one I can’t comment further.

      N95 > surgical > cloth masks (I think about 65 percent was the last study I saw). That said, health workers used to wear cloth workers before we got disposable ones. Droplets gonna droplet less with any barrier.

          Some pics I saw online about HK volunteers giving out DIY cloth masks to janitors. Urban density is a likely factor in “mask culture”. I also think these show people will find ways to filter droplets w/ the tool they have while trying not to worsen the mask shortage among medics.pic.twitter.com/4UbAGf3auT
