We did not believe that the Corona would be here even after two years, and certainly not that the discussion about masks would continue to be relevant, but reality aside and hopes aside.

The U.S. Centers for Disease Control and Prevention admitted over the weekend that fabric masks are less effective than surgical masks in protecting against COVID-19



. "Provide the least protection, thinly woven products in layers offer more protection, disposable surgical masks are good and KN95 masks offer even more protection," according to the new guidelines released on Friday.

But the CDC did not go so far as to say that cloth masks are not suitable against this strain of the virus - something that a number of public health experts say is clear given the rates of infection.

Instead, the new guideline states that masks, such as N95 or KN95 masks, "may be considered a priority in certain situations and by certain people when greater protection is needed. This may include scenarios involving infected patients or people with comorbidities, or when social distance is not "It's possible," the CDC said.

Not sure they help.

This is a change from an earlier stage in the epidemic when the CDC, which was concerned about a shortage of protective equipment, urged people to leave the N95 masks to health care workers.



These masks are considered to be the most effective in filtering viral particles.

They create the best seal around the mouth and nose and allow almost no leakage (in or out) of viral particles.

They also contain coiled fibers that prevent the passage of airborne pathogens.

This is also the reason why health agencies around the world have recommended that these masks be stocked for medical workers, who are at the forefront of the fight in Corona and exposed to many patients.



Their early analysis revealed that the N99 mask reduces the chances of infection by 94-99 percent, after 20 minutes of exposure in a high-pollution environment.

The N95 mask provides almost identical protection.

Recent data shows that they may protect those wearing them from people infected with the micron, for two and a half hours, compared to only 20 to 30 minutes of protection from fabric or surgical masks.
