Lengthy after most nations urged their citizens to don masks, and following months of hand-wringing about the caliber of the evidence out there, the earth Well being Organization on Friday endorsed 마스크 the use of encounter masks by the public to lessen transmission from the coronavirus.
Considering that the start of the pandemic, amazingly, the W.H.O. experienced refused to endorse masks. The announcement was long overdue, critics claimed, as masks are an easy and cheap preventive evaluate.
Even in its most recent advice, the W.H.O. manufactured its reluctance abundantly clear, saying the usefulness of experience masks is “not but supported by top quality or immediate scientific proof,” but that governments need to encourage mask carrying because of “a growing compendium of observational evidence.”
The W.H.O. also presented an exhaustive list of the potential shortcomings of putting on a mask, which include “problems with communicating clearly” and “likely pain.”
A examine funded through the W.H.O. concluded this week that respirator masks, such as the N95, are better than surgical masks for wellbeing treatment workers. In addition it discovered that deal with shields, goggles and glasses may possibly give additional defense within the coronavirus.
Although the W.H.O. didn't budge from its past tips for health care staff, declaring that respirator masks are only essential if these types of workers are linked to techniques that deliver virus-laden aerosols — droplets smaller sized than five microns.
Other than These instances, transmission with the virus thus far has only been demonstrated for greater droplets and by Get in touch with, mentioned Dr. Benedetta Allegranzi, an infectious disease expert and technological guide for the W.H.O.
Even though experiments have revealed that viral R.N.A. is present inside the air in specified overall health treatment options, “transmission differs, and it hasn't been shown,” she reported.
“It https://en.search.wordpress.com/?src=organic&q=마스크 is disappointing the W.H.O. is dismissing that most current evidence that N95s are far more effective than surgical masks in shielding overall health care workers from Covid-19 exposure,” reported David Michaels, an epidemiologist at George Washington College who headed the Occupational Safety and Well being Administration through the Obama administration.
“If the condition would be the lack of N95s, the W.H.O. need to accept that and never pretend that medical masks are equally powerful.”
