15 Best N95, KF94, and KN95 Face Masks (2022) | WIRED
15 Best N95, KF94, and KN95 Face Masks (2022) | WIRED: According to a report from spring 2021, if an infected and noninfected person were both wearing cloth masks, it would take around 27 minutes for an infectious dose of Covid-19 to reach the noninfected person. If both were wearing surgical masks, that time would rise to about an hour. If both were wearing non-fitted N95s, it would take 25 hours to receive an infectious dose. This was before the Delta or Omicron variants, but it should offer an idea of the masks' relative effectiveness levels.

This is pretty cool! I have quit thinking about variants when they seemed to be getting less deadly.
CGP Gray mentioned that variants are getting more transmissible but less deadly. I'd like to read more research about that.
