Research last summer and in 2020 led by Khosronejad found that even normal breathing can lead to a "jet of saliva particles" invisible to the naked eye that can travel more than 9 feet.Indoors, "Just wearing a cloth mask, you can curb the spreading to less than 2 feet away from the person," Khosronejad said.N95s are the most effective masks in blocking the spreading of saliva particles and in preventing the inhalation of the particles, followed by KN95s, surgical masks and cloth masks, he said.The research was done pre-omicron, but, he said, "The physics of saliva particle transport should be similar for various variants." In addition, although the contagiousness of omicron means that cloth and surgical masks in particular are less effective with omicron than with other variants, they still help reduce the inhalation of particles, and are better than no mask at all, he said.A 2020 study by researchers at Northeastern University in Boston found that fabric masks varied greatly in effectiveness depending on the fit and shape of the mask, ranging from less than 30% removal of particles to nearly 90%.A tighter fit and filtering material is why N95s are better than other masks, Caravanos said."It’s all about leakage" of air from the neck and cheek areas, he said.
...Caravanos said there’s no evidence masks harm children’s or adults’ health."All of that has been disproven," he said.
I think the n-95 works a little. But the others don't.
Cdc admitted it. All over the news. Thing about it is.. those 95 masks are hard to wear for very long.
And its cruel to put kids thru that. And that's exactly what a doctor said too about the 95 on kids.
As soon as the kid fidgits-breaks the seal … don't work.
keep a Kid from doing that. Good luck.
Surgeons wear them mostly not to spread bacteria into a patient on the operating table. Same reason they wear gloves. staph and mrsa.
