Long following most nations urged their citizens to have on masks, and just after months of hand-wringing about the caliber of the evidence available, the whole world Overall health Organization on Friday endorsed the usage of deal with masks by http://edition.cnn.com/search/?text=마스크 the general public to lower transmission of your coronavirus.
Due to the fact the beginning of your pandemic, surprisingly, the W.H.O. had refused to endorse masks. The announcement was long overdue, critics mentioned, as masks are a simple and cheap preventive evaluate.
Even in its newest steering, the W.H.O. manufactured its reluctance abundantly clear, declaring the usefulness of encounter masks is “not but supported by superior quality or immediate scientific proof,” but that governments really should persuade mask wearing as a result of “a expanding compendium of observational evidence.”
The W.H.O. also supplied an exhaustive listing of the potential down sides of putting on a mask, like “problems with speaking Obviously” and “likely discomfort.”
A study funded from the W.H.O. concluded this 7 days that respirator masks, similar to the N95, are better than surgical masks for health treatment employees. In addition, it located that facial area shields, goggles and glasses may perhaps provide additional protection from the coronavirus.
However the W.H.O. didn't budge from its former suggestions for professional medical personnel, expressing that respirator masks are only necessary if such employees are involved in techniques that create virus-laden aerosols — droplets scaled-down than five microns.
In addition 마스크 to Those people situations, transmission in the virus thus far has only been demonstrated for much larger droplets and by Get hold of, stated Dr. Benedetta Allegranzi, an infectious disease pro and technological direct with the W.H.O.
While studies have demonstrated that viral R.N.A. is present in the air in specified wellness treatment configurations, “transmission is different, and it has not been demonstrated,” she stated.
“It is actually disappointing the W.H.O. is dismissing that most up-to-date proof that N95s are far more practical than surgical masks in protecting health treatment personnel from Covid-19 publicity,” explained David Michaels, an epidemiologist at George Washington University who headed the Occupational Basic safety and Well being Administration over the Obama administration.
“If the challenge is the lack of N95s, the W.H.O. must accept that instead of faux that health care masks are equally efficient.”
