Extended soon after most nations urged their citizens to put on masks, and soon after months of hand-wringing about the quality of the proof accessible, the earth Wellbeing Group on Friday 마스크 endorsed using experience masks by the general http://edition.cnn.com/search/?text=마스크 public to scale back transmission with the coronavirus.
Due to the fact the beginning of your pandemic, astonishingly, the W.H.O. had refused to endorse masks. The announcement was extended overdue, critics stated, as masks are an easy and inexpensive preventive measure.
Even in its most up-to-date guidance, the W.H.O. built its reluctance abundantly very clear, saying the usefulness of encounter masks is “not yet supported by top quality or immediate scientific proof,” but that governments ought to stimulate mask sporting on account of “a developing compendium of observational proof.”
The W.H.O. also offered an exhaustive list of the opportunity negatives of carrying a mask, such as “trouble with communicating Obviously” and “prospective discomfort.”
A study funded with the W.H.O. concluded this 7 days that respirator masks, just like the N95, are a lot better than surgical masks for well being care employees. What's more, it identified that encounter shields, goggles and Eyeglasses could present extra protection within the coronavirus.
Nevertheless the W.H.O. did not budge from its past suggestions for professional medical workers, indicating that respirator masks are only required if this kind of employees are involved with processes that crank out virus-laden aerosols — droplets scaled-down than 5 microns.
Besides those circumstances, transmission on the virus so far has only been demonstrated for larger sized droplets and by Make contact with, said Dr. Benedetta Allegranzi, an infectious disease pro and complex lead to the W.H.O.
Even though scientific tests have proven that viral R.N.A. is present inside the air in selected well being treatment configurations, “transmission is different, and it has not been shown,” she reported.
“It's disappointing which the W.H.O. is dismissing that most up-to-date proof that N95s are considerably simpler than surgical masks in guarding wellbeing care staff from Covid-19 publicity,” reported David Michaels, an epidemiologist at George Washington University who headed the Occupational Basic safety and Wellbeing Administration over the Obama administration.
“If the issue is the lack of N95s, the W.H.O. should really admit that rather than faux that medical masks are equally efficient.”
