Studies are emerging that cloth masks are not effective in preventing the spread of COVID.
A study released in November by researchers at Yale University, Stanford University and others found that villages in Bangladesh, India, where surgical masks were worn had 11% fewer cases of COVID than in villages where no masks were worn. In villages that wore cloth masks, infections were reduced by only 5%.
"There is emerging evidence that a surgical mask or a hospital or a medical grade mask does a better job of preventing respiratory droplets carrying the virus to other people around you," said Dr. Adi Shah with the Mayo Clinic.
