Extensive after most nations urged their citizens to don masks, and just after months of hand-wringing about the standard 마스크 of the proof out there, the globe Health and fitness Organization on Friday endorsed the usage of deal with masks by the general public to lessen transmission with the coronavirus.
Considering the fact that the start in the pandemic, amazingly, the W.H.O. had refused to endorse masks. The announcement was extended overdue, critics reported, as masks are a fairly easy and cheap preventive measure.
Even in its most recent direction, the W.H.O. manufactured its reluctance abundantly obvious, saying the usefulness of encounter masks is “not still supported by superior quality or immediate scientific proof,” but that governments ought to stimulate mask putting on as a consequence http://edition.cnn.com/search/?text=마스크 of “a rising compendium of observational evidence.”
The W.H.O. also offered an exhaustive list of the opportunity negatives of sporting a mask, such as “problem with speaking Plainly” and “opportunity discomfort.”
A study funded from the W.H.O. concluded this 7 days that respirator masks, like the N95, are better than surgical masks for wellbeing treatment employees. It also discovered that face shields, goggles and Eyeglasses may well give supplemental security from the coronavirus.
Even so the W.H.O. did not budge from its prior suggestions for medical workers, saying that respirator masks are only wanted if these types of workers are involved with methods that crank out virus-laden aerosols — droplets smaller than five microns.
Apart from These situation, transmission on the virus so far has only been shown for larger droplets and by Get hold of, claimed Dr. Benedetta Allegranzi, an infectious condition skilled and technical direct for your W.H.O.
Whilst scientific tests have proven that viral R.N.A. is present from the air in certain well being treatment options, “transmission is different, and it has not been shown,” she stated.
“It's disappointing the W.H.O. is dismissing that latest proof that N95s are much more effective than surgical masks in protecting wellbeing treatment workers from Covid-19 exposure,” claimed David Michaels, an epidemiologist at George Washington University who headed the Occupational Security and Overall health Administration in the course of the Obama administration.
“If the issue may be the lack of N95s, the W.H.O. really should accept that rather than faux that health-related masks are equally effective.”
