Lengthy just after most nations urged their citizens to wear masks, and after months of hand-wringing about the quality of https://www.washingtonpost.com/newssearch/?query=마스크 the evidence readily available, the globe Health and fitness Firm on Friday endorsed the use of deal with masks by the public to reduce transmission of your coronavirus.
Considering the fact that the start with the pandemic, remarkably, the W.H.O. experienced refused to endorse masks. The announcement was prolonged overdue, critics stated, as masks are an easy and cheap preventive evaluate.
Even in its hottest guidance, the W.H.O. designed its reluctance abundantly crystal clear, indicating the usefulness of experience masks is “not but supported by premium quality or direct scientific proof,” but that governments really should encourage mask putting on because of “a increasing compendium of observational proof.”
The W.H.O. also presented an exhaustive listing of the probable down sides of carrying a mask, like “problems with communicating clearly” and “likely distress.”
A review funded via the W.H.O. concluded this week that respirator masks, like the N95, are much better than surgical masks for well being care workers. It also uncovered that deal with shields, goggles and glasses may perhaps give extra protection through the coronavirus.
But the W.H.O. didn't budge from its previous suggestions for health care workers, saying that respirator masks are only essential if this sort of employees are linked to methods that crank out virus-laden aerosols — droplets scaled-down than five microns.
Aside from These situation, transmission in the virus up to now has only been shown for larger sized droplets and by Call, stated Dr. Benedetta Allegranzi, an infectious sickness skilled and complex guide to the W.H.O.
Though scientific studies have demonstrated that viral R.N.A. is current from the air in sure wellness care configurations, “transmission differs, and it hasn't been demonstrated,” she mentioned.
“It really is disappointing which the W.H.O. is dismissing that 마스크 most current proof that N95s are much simpler than surgical masks in guarding health and fitness treatment workers from Covid-19 publicity,” claimed David Michaels, an epidemiologist at George Washington College who headed the Occupational Safety and Health and fitness Administration over the Obama administration.
“If the challenge is the scarcity of N95s, the W.H.O. ought to admit that rather than fake that healthcare masks are Similarly helpful.”
