MASK UP:
Why we need to wear better masks (Will Chase, 1/11/22, Axios)
The big picture: Fitted particle-filtering masks like N95s are up to 75 times more effective at preventing infection with COVID-19 than surgical masks, according to a study published recently in the Proceedings of the National Academy of Sciences.This echoes recent recommendations by public health experts about the value of N95 masks, reported by the Wall Street Journal.It will take 25 hours for an infectious dose of COVID-19 to transmit between people wearing non-fit-tested N95 respirators but if they're wearing a tightly sealed N95, they'll have 2,500 hours of protection, per a study reported by the WSJ.
