At least according to two studies, one at MIT and the other at Stanford. I have to say I was a little surprised at the MIT study on social distancing. They concluded that when we exhale the warm air rises and distributes around the room and the risk of being exposed is about the same up to 60 feet away. They concluded that the length of exposure was the key, not the distance. Also said that fresh air in a room was more effective than fancy filters, which is common sense. They concluded that masks made no difference in infection rates and had the data to prove it. Also skewered the people wearing masks outdoors as completely unnecessary.
As for the Stanford study, they concluded what I have been saying all along. Masks provide no protection from infection, including the kind worn by medical personnel. It was a pretty brutal assessment of the science of masks and covered all the essential points I have made over the last year. They also focused on the deletrious effects of masks and concluded they not only have no value in preventing infection but have negative impacts in other ways. Follow the science or follow unelected bureaucrats.....it's a free country. Me, I'll follow the science.
But hey, that's just Stanford and MIT scientists.....what do they know anyway, right? We've got Dr. Fauci who has pretty much taken every position on every issue and changed course multiple times. Wonder if Dementia Joe is getting tired of his waffling yet. Nah.....Joe probably doesn't even remember his name. Speaking of Joe, seen him lately? Yup...me neither.
