Long right after most nations urged their citizens to wear masks, and after months of hand-wringing about the quality of the proof available, the planet Health Organization 마스크 on Friday endorsed using confront masks by the general public to scale back transmission from the coronavirus.
Due to the fact the beginning of your pandemic, remarkably, the W.H.O. had refused to endorse masks. The announcement was very long overdue, critics reported, as masks are a straightforward and cheap preventive measure.
Even in its most recent steering, the W.H.O. made its reluctance abundantly crystal clear, indicating the usefulness of face masks is “not but supported by high quality or direct scientific proof,” but that governments need to persuade mask carrying as a consequence https://www.washingtonpost.com/newssearch/?query=마스크 of “a increasing compendium of observational evidence.”
The W.H.O. also provided an exhaustive listing of the possible disadvantages of carrying a mask, together with “trouble with communicating Evidently” and “likely 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 well being treatment staff. Additionally, it found that confront shields, goggles and glasses may supply extra defense within the coronavirus.
Even so the W.H.O. didn't budge from its prior recommendations for clinical workers, expressing that respirator masks are only desired if this kind of personnel are associated with techniques that create virus-laden aerosols — droplets smaller than five microns.
Aside from Those people conditions, transmission in the virus to this point has only been demonstrated for more substantial droplets and by Get hold of, said Dr. Benedetta Allegranzi, an infectious sickness specialist and specialized guide with the W.H.O.
Whilst reports have demonstrated that viral R.N.A. is present while in the air in specific well being care configurations, “transmission is different, and it hasn't been demonstrated,” she stated.
“It can be disappointing the W.H.O. is dismissing that newest evidence that N95s are considerably more effective than surgical masks in safeguarding wellbeing care personnel from Covid-19 publicity,” claimed David Michaels, an epidemiologist at George Washington College who headed the Occupational Safety and Health Administration during the Obama administration.
“If the issue will be the lack of N95s, the W.H.O. should really acknowledge that instead of pretend that clinical masks are equally productive.”
