Very long right after most nations urged their citizens to have on masks, and soon after months of hand-wringing about the caliber of the evidence out there, the World Wellness Corporation on Friday endorsed the use of face masks by the public to lessen transmission from the coronavirus.
Since the start on the pandemic, surprisingly, the W.H.O. experienced refused to endorse masks. The announcement was prolonged overdue, critics mentioned, as masks are a simple and inexpensive preventive evaluate.
Even 마스크 in its most up-to-date direction, the W.H.O. built its reluctance abundantly obvious, saying the usefulness of facial area masks is “not but supported by good quality or direct scientific evidence,” but that governments ought to stimulate mask putting on because of “a growing compendium of observational evidence.”
The W.H.O. also supplied an exhaustive listing of the prospective cons of carrying a mask, such as “issue with communicating clearly” and “potential irritation.”
A examine funded from the W.H.O. concluded this 7 days that respirator masks, just like the N95, are better than surgical masks for overall health treatment personnel. In addition it found that confront shields, goggles and glasses may present added protection from your coronavirus.
But the W.H.O. did not budge from its former suggestions for professional medical staff, stating that respirator masks are only essential if these types of employees are linked to techniques that crank out virus-laden aerosols — droplets scaled-down than 5 microns.
Apart from those instances, transmission in the virus to date has only been demonstrated for larger droplets and by Call, reported Dr. Benedetta Allegranzi, an infectious illness professional and technological guide to the W.H.O.
Although studies have proven that viral R.N.A. is present inside the air in sure wellbeing care options, “transmission differs, and it hasn't been shown,” she claimed.
“It's disappointing that the W.H.O. is dismissing that hottest evidence that N95s are far simpler than surgical masks in preserving well being http://www.bbc.co.uk/search?q=마스크 treatment personnel from Covid-19 exposure,” explained David Michaels, an epidemiologist at George Washington University who headed the Occupational Safety and Wellness Administration in the Obama administration.
“If the issue could be the lack of N95s, the W.H.O. must admit that rather than pretend that health-related masks are equally efficient.”
