Extended immediately after most nations urged their citizens to wear 마스크 masks, and after months of hand-wringing about the standard of the evidence readily available, the World Health and fitness Firm on Friday endorsed using confront masks by the general public to reduce transmission on the coronavirus.
Given that the beginning from the pandemic, remarkably, the W.H.O. had refused to endorse masks. The announcement was very long overdue, critics said, as masks are a fairly easy and inexpensive preventive http://www.bbc.co.uk/search?q=마스크 evaluate.
Even in its latest steering, the W.H.O. produced its reluctance abundantly apparent, declaring the usefulness of experience masks is “not however supported by premium quality or immediate scientific evidence,” but that governments ought to stimulate mask putting on because of “a increasing compendium of observational proof.”
The W.H.O. also presented an exhaustive listing of the prospective shortcomings of sporting a mask, including “issues with speaking Evidently” and “likely irritation.”
A review funded from the W.H.O. concluded this 7 days that respirator masks, such as the N95, are much better than surgical masks for wellbeing care personnel. Additionally, it located that face shields, goggles and glasses may perhaps offer you supplemental security within the coronavirus.
However the W.H.O. didn't budge from its past recommendations for health care workers, saying that respirator masks are only required if this sort of staff are involved with strategies that produce virus-laden aerosols — droplets smaller sized than 5 microns.
In addition to People conditions, transmission from the virus thus far has only been shown for bigger droplets and by Call, stated Dr. Benedetta Allegranzi, an infectious condition specialist and technical direct to the W.H.O.
Although research have proven that viral R.N.A. is present while in the air in specified health treatment configurations, “transmission is different, and it has not been shown,” she stated.
“It truly is disappointing that the W.H.O. is dismissing that most up-to-date proof that N95s are considerably more effective than surgical masks in preserving overall health care personnel from Covid-19 publicity,” stated David Michaels, an epidemiologist at George Washington University who headed the Occupational Safety and Health and fitness Administration through the Obama administration.
“If the situation will be the shortage of N95s, the W.H.O. need to admit that instead of faux that healthcare masks are Similarly productive.”
