Very long after most nations urged their citizens to wear masks, and after months of hand-wringing about the caliber of the proof accessible, the http://edition.cnn.com/search/?text=마스크 entire world Overall health Group on Friday endorsed using confront masks by the general public to lessen transmission of the coronavirus.
Given that the beginning of the pandemic, amazingly, the W.H.O. had refused to endorse masks. The announcement was extended overdue, critics claimed, as masks are an uncomplicated and inexpensive preventive measure.
Even in its most recent steerage, the W.H.O. built its reluctance abundantly crystal clear, stating the usefulness of facial area masks is “not however supported by high-quality or direct scientific proof,” but that governments should encourage mask carrying because of “a rising compendium of observational proof.”
The W.H.O. also supplied an exhaustive list of the prospective down sides of donning a mask, like 마스크 “problem with communicating clearly” and “opportunity irritation.”
A analyze funded by the W.H.O. concluded this week that respirator masks, such as N95, are a lot better than surgical masks for health treatment workers. What's more, it discovered that deal with shields, goggles and glasses may perhaps present further safety from the coronavirus.
Though the W.H.O. did not budge from its previous tips for medical staff, saying that respirator masks are only required if this kind of staff are involved with strategies that produce virus-laden aerosols — droplets lesser than five microns.
Other than those situations, transmission with the virus so far has only been shown for more substantial droplets and by contact, stated Dr. Benedetta Allegranzi, an infectious sickness qualified and complex direct for your W.H.O.
Even though scientific tests have revealed that viral R.N.A. is present while in the air in particular overall health treatment configurations, “transmission differs, and it hasn't been demonstrated,” she claimed.
“It's disappointing the W.H.O. is dismissing that latest evidence that N95s are significantly simpler than surgical masks in protecting wellbeing treatment employees from Covid-19 publicity,” stated David Michaels, an epidemiologist at George Washington College who headed the Occupational Safety and Wellness Administration in the Obama administration.
“If the problem is the lack of N95s, the W.H.O. really should admit that rather than fake that clinical masks are Similarly powerful.”
