Про эффективность масок
2021-11-08 21:04Наконец появились хоть какие-то данные про эффективность масок. Не прошло и двух лет.
"...Those where masks of any type were worn had about 9% fewer symptomatic cases of COVID-19."
"Villages where surgical masks were worn had 11% fewer COVID-19 cases than villages in where masks were not worn. In villages where cloth masks were worn, on the other hand, infections were reduced by only 5%."
"People 50 to 60 years who wore surgical masks were 23% less likely to test positive for COVID compared to their peers who didn't wear masks. For people older than 60, the reduction in risk was greater — 35%."
