Corona viruses aren't novel, the common cold is one of them.
There were no accurate spread models in 2020, no studies how masks would affect the spread of the common cold.
There was ridiculous advice that the famous droplets would sink to the ground before covering a distance > 1.5 meters,
that masks would not help at all and much more.
Now they admit that the virus is airborne!
Sorry, #FollowTheScience slogans and calling others fools does not help.
- throwaway210222 5y ago> There was ridiculous advice that the famous droplets would sink to the ground before covering a distance > 1.5 meters, This was based on experience with the original SARS virus. Take this 2003 paper for example: "Effectiveness of precautions against droplets and contact in prevention of nosocomial transmission of severe acute respiratory syndrome (SARS)" [1] It was a case control study in a Hong Kong hospital that concluded: "Practice of droplets precaution and contact precaution is adequate in significantly reducing the risk of infection …. The protective role of the mask suggests … infection is transmitted by droplets." Following the science really, really does help. You just need to do it; fools of course don't.

- throwaway129821 5y agoYour study, while pushing the large droplet theory, asserts that masks are useful which the official science denied in the beginning of 2020. Droplets themselves are being questioned now: https://www.thelancet.com/article/S0140-6736(21)00869-2/fulltext https://www.thelancet.com/article/S0140-6736(21)00869-2/full... Have fun following the science! Reading might help.
