Lengthy soon after most nations urged their citizens to put on masks, and after months of hand-wringing about the caliber of the evidence offered, the whole world Health Organization on Friday endorsed the use of face masks by the general public to http://www.bbc.co.uk/search?q=마스크 scale back transmission on the coronavirus.
Because the beginning from the pandemic, amazingly, the W.H.O. had refused to endorse masks. The announcement was prolonged overdue, critics explained, as masks are a straightforward and cheap preventive evaluate.
Even in its hottest steering, the W.H.O. built its reluctance abundantly crystal clear, expressing the usefulness of confront masks is “not nevertheless supported by high quality or direct scientific proof,” but that governments should stimulate mask putting on due to “a increasing compendium of observational evidence.”
The W.H.O. also presented 마스크 an exhaustive listing of the possible down sides of sporting a mask, like “trouble with speaking clearly” and “likely distress.”
A analyze funded with the W.H.O. concluded this 7 days that respirator masks, much like the N95, are better than surgical masks for wellbeing care employees. What's more, it located that face shields, goggles and Eyeglasses may well offer you additional safety with the coronavirus.
Even so the W.H.O. didn't budge from its past recommendations for medical personnel, indicating that respirator masks are only desired if this kind of workers are involved with processes that produce virus-laden aerosols — droplets smaller sized than five microns.
Apart from Those people instances, transmission in the virus up to now has only been demonstrated for larger sized droplets and by Get hold of, explained Dr. Benedetta Allegranzi, an infectious disorder pro and complex direct for the W.H.O.
Even though experiments have shown that viral R.N.A. is present from the air in sure well being treatment options, “transmission differs, and it hasn't been demonstrated,” she explained.
“It is actually disappointing the W.H.O. is dismissing that most current evidence that N95s are significantly more effective than surgical masks in guarding overall health treatment staff from Covid-19 publicity,” reported David Michaels, an epidemiologist at George Washington College who headed the Occupational Basic safety and Health Administration throughout the Obama administration.
“If the issue may be the shortage of N95s, the W.H.O. must admit that rather than pretend that healthcare masks are equally successful.”
