Well, it looks like the #DropletDogma has been proven wrong! #N95 masks are up to 75 times more effective than surgical masks in preventing #COVID19 transmission, according to a recent study.

A separate experiment from the study found that social distancing barely helped, with the infection risk reaching 80% after just one minute, and 99.9% after 20 minutes.
The fit of the mask is the most important factor, Bodenschatz, said. “It turns out that leakage dominates over filtration.” Masks should have a tight fit around the face and nose to minimize any air leakage.
The bottom line: The difference in risk between universal and mixed masking behavior is huge.
“We were surprised how well universal masking can reduce the risk of infection..." the researchers said.
I'm not surprised 🤓

Bodenschatz said. "If we wear masks well the virus will have a hard time. The risk of infection without masks is very high.” #BringBackMasks
