  1. ​ @simon-ec5kv  also, "empirical studies indicate that asymptomatic infections account for 17.9 to 30.8% of all infections (5, 6)," . So see references 6 and 7. (You can copy past their titles or authors into google scholar to get to the actual papers.)

  2. N95 are way more effective and more comfortable than the surgical type. they should be mailing them to everone

  3. source? that seems likely but I wasn't aware of any good data

  4.  @georgeinjapan6583  That is interesting statement from the WHO, but I don't see any links to studies or data. Nice website though, lots of other studies.

  5.  @simon-ec5kv  From a search of https://scholar.google.com/, first page of results: . "We found that the ma-jority of incidences may be attributable to silent transmission from acombination of the presymptomatic stage and asymptomatic infec-tions. Consequently,even if all symptomatic cases are isolated, a vastoutbreak may nonetheless unfold" . from Moghadas et al 2020. The implications of silent transmission for the controlof COVID-19 outbreaks. Proceedings of the National Academy of Sciences 2020. https://www.pnas.org/content/pnas/117/30/17513.full.pdf

  6.  @simon-ec5kv  What about the methods, specifically?

  7. ​ @simon-ec5kv  Fair enough! Only two small studies were cited for the asymptomatic ratio. . Do you have a citation for what I assume is much better evidence? Surely there are population wide random sample surveys that estimate asymptomatic ratios. . Of course, there are two things at play in "silent transmission": asymptomatic, and presymptomatic. Everyone that gets sick has a presymptomatic phase, averaging a couple days, and they can be infectious during this time.

  8.  @geoffnelson6756  The Danish study concluded that the benefit of mask use was in the interval (-27, + 47). In other words, the data were consistent with anything from a mask benefit of 47% risk reduction to a mask harmfullness of 27% increase in risk. . "More study is needed" type situation. . A meta analysis of 174 studies concluded masks gave 14% risk reduction, and eye protection 10% more. But a "mask" is like an "animal" it is useful to be more specific. They aren't all N95s. Should be, aren't.
