The bangladesh study showed that groups of people that are spending large portion of their days inside small huts will benefit from mask. One particular area was also mosques which has a large number of people coming and going, with people being near each other indoors. Mask makes great sense in specific contexts. Near vulnerable groups. In tight spaces and areas of low ventilation. In areas where a large number of people meet. The further away from such areas, the less evidence we get. There is a reason why conferences is generally associated with people getting sick, while the same can't be said about the beach.

Sure, skip the mask at the beach. We've known outdoors is likely quite safe due to ventilation for a long time now. The Bangladesh study is likely informative in busy grocery stores, retail, offices, schools, etc.; certainly more than just "inside small huts".

  > The Bangladesh study is likely informative in busy grocery stores, retail, offices, schools, etc.; certainly more than just "inside small huts". The study did not show that. It was a study conducted in rural areas of Bangladesh, areas with small villages of huts and some mosque. Those are quite different from a large city mall and office complex. Schools are a even more complex since while children has a significant higher rate of getting sick in general, the transmission rate between children and adults is significant lower. The ruling on school lock downs and mask in schools has yet to be established. We can look at specific examples. If you are on a packed plane then a mask is pretty good idea. Traveling on a bike then it is unlikely to do anything good. Mask in crowded open floor plan with bad ventilation, yes. Mask in personalized offices with good ventilation, no. A conferences, yes. A school, maybe. A bench, no. A large grocery store in off-hours, less likely. A crowded grocery store in rush hours, more likely. In a public bath house, the data seems to indicate no. Things that seems to correlate with transmission rates seems to primarily be about: distance between people, ventilation and humidity, practicality of staying isolated at symptoms, age and risk groups. Raise any attribute of those to an extreme and one can get data that either prove or disprove masks as effective.
