Extensive soon after most nations urged their citizens to wear masks, and following months of hand-wringing http://edition.cnn.com/search/?text=마스크 about the caliber of the proof offered, the globe Health Group on Friday endorsed using deal with masks by the public to lower transmission on the coronavirus.
Because the beginning with the pandemic, remarkably, the W.H.O. had refused to endorse masks. The announcement was extensive overdue, critics claimed, as masks are an uncomplicated and cheap preventive evaluate.
Even in its hottest direction, the W.H.O. built its reluctance abundantly clear, expressing the usefulness of deal with masks is “not nonetheless supported by premium quality or direct scientific evidence,” but that governments should persuade mask wearing as a result of “a escalating compendium of observational evidence.”
The W.H.O. also offered an exhaustive list of the prospective cons of sporting a mask, such as “problem with speaking Evidently” and “potential discomfort.”
A study funded because of the W.H.O. concluded this week that respirator masks, just like the N95, are much better than surgical masks for overall health treatment staff. In addition, it located that confront shields, goggles and glasses may give extra defense from your coronavirus.
Even so the W.H.O. did not budge from its previous recommendations for healthcare workers, declaring that respirator masks are only necessary if this sort of staff are involved with treatments that crank out virus-laden aerosols — droplets smaller than 5 microns.
Other than People situation, transmission on the virus to date has only been demonstrated for bigger droplets and by Get in touch with, explained Dr. Benedetta Allegranzi, an infectious sickness skilled and complex guide for that W.H.O.
Although experiments have revealed that viral R.N.A. is current within the air in certain overall health treatment configurations, “transmission differs, and 마스크 it hasn't been shown,” she claimed.
“It truly is disappointing which the W.H.O. is dismissing that latest proof that N95s are significantly simpler than surgical masks in guarding health and fitness care workers from Covid-19 publicity,” stated David Michaels, an epidemiologist at George Washington University who headed the Occupational Security and Health Administration through the Obama administration.
“If the trouble could be the scarcity of N95s, the W.H.O. need to accept that and not fake that health care masks are equally powerful.”
