Extended just after most nations urged their citizens to don masks, and following months of hand-wringing about the standard of the evidence available, the entire world Well being Corporation on Friday endorsed the use of experience masks by 마스크 the general public to scale back transmission with the coronavirus.
Considering the fact that the beginning on the pandemic, surprisingly, the W.H.O. experienced refused to endorse masks. The announcement was very long overdue, critics said, as masks are a straightforward and cheap preventive measure.
Even in its latest assistance, the W.H.O. made its reluctance abundantly apparent, indicating the usefulness of deal with masks is “not but supported by high-quality or direct scientific proof,” but that governments ought to inspire mask putting on as a consequence of “a expanding compendium of observational evidence.”
The W.H.O. also presented an exhaustive list of the possible disadvantages of wearing a mask, such as “issues with speaking Obviously” and “probable irritation.”
A research funded from the W.H.O. concluded this week that respirator masks, such as the N95, are a lot better than surgical masks for well being treatment personnel. In addition it found that experience shields, goggles and glasses may give added safety through the coronavirus.
Even so the W.H.O. didn't budge from its prior tips for professional medical workers, stating that respirator masks are only wanted if this kind of employees are associated with strategies that deliver virus-laden aerosols — droplets more compact than five microns.
Apart from Those people instances, transmission on the virus so far has only been demonstrated for larger sized droplets and by contact, reported Dr. Benedetta Allegranzi, an infectious sickness professional and specialized guide for the W.H.O.
While http://edition.cnn.com/search/?text=마스크 research have proven that viral R.N.A. is existing during the air in certain overall health treatment settings, “transmission differs, and it has not been demonstrated,” she explained.
“It is disappointing which the W.H.O. is dismissing that most current proof that N95s are far more practical than surgical masks in preserving health care personnel from Covid-19 exposure,” said David Michaels, an epidemiologist at George Washington University who headed the Occupational Basic safety and Overall health Administration throughout the Obama administration.
“If the condition would be the lack of N95s, the W.H.O. ought to admit that and not pretend that professional medical masks are Similarly helpful.”
