According to the Centers for Disease Control and Prevention, wearing a face mask can also help protect you from coronavirus – not just others.
The CDC’s new guidelines have updated its previous statement that the main benefit of wearing a mask is to help infected people prevent others from spreading the disease.
“Adopting universal masking policies can help avoid future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distance, hand hygiene and adequate ventilation,” the CDC said.
“The preventive benefit of masking has been taken from a combination of resource control and personal protection for the mask wearer,” he says.
According to the agency, “the relationship between resource control and personal protection is potentially complementary and possibly covalent, so that personal gain increases with the increasing use of community masks.”
“Studies have shown that cloth mask materials can also reduce the exposure of wearers to infectious drops through purification, including fine drops and filtration of particles less than 10 microns.”
The CDC also cited varying degrees of “relative filtration effectiveness” provided by various masks based on various studies, “largely due to changes in experimental design and particle size analysis.”
The CDC said, “Multiple layers of high-thread counted fabrics show better performance than single layers of low-thread counted fabrics, in some cases filtering up to 50% fine particles less than 1 micron.”
Some materials, including polypropylene, can improve filtering effectiveness by creating a kind of static electricity, which increases the holding power of charged particles.
The agency added that others like silk will help remove sticky drops and reduce fabric dampness and maintain breathing and comfort.
To prevent inhaled viruses, the CDC said, “Cloth masks effectively block most large droplets (i.e., 20–30 microns and larger) but they also prevent tiny tiny tiny tiny tiny tiny tiny. Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny Tiny More than 10 microns. “
It added that multi-layer cloth masks can both prevent fine drops by up to 70 per cent and limit the spread of non-caught.
The agency said more than 100 percent of human experiments found a barrier that measured blocking all respiratory droplets, with some studies comparing cloth masks to surgical masks as barriers to source control.
