Face masks to prevent transmission of influenza virus: a systematic review (2014)
> There is some evidence to support the wearing of masks or respirators during illness to protect others, and public health emphasis on mask wearing during illness may help to reduce influenza virus transmission.
> There are fewer data to support the use of masks or respirators to prevent becoming infected.

- istjohn 7y agoInterestingly, the submitted article finds the opposite. According to it, masks are more useful when worn by healthy people than when worn by sick people.
- SiempreViernes 7y agoWell, the OP just tested how well masks filter particles, and made comments based on these results. They didn't actually study health outcomes, while the review I linked did find studies of health outcomes but didn't find any statistically significant results. On balance, masks in general usage probably help a tiny bit, but it it's much more important to wash your hands properly, so you're better of buying soap and paper towels.
- istjohn 7y agoThat's a false choice.
