Long immediately after most nations urged their citizens to dress in masks, and soon after months of hand-wringing about the caliber of the proof accessible, the whole world Overall health Firm on Friday endorsed http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/마스크 the use of deal with masks by the general public to reduce transmission from the coronavirus.
Because the beginning from the pandemic, surprisingly, the W.H.O. had refused to endorse masks. The announcement was prolonged overdue, critics claimed, as masks are a fairly easy and cheap preventive evaluate.
Even in its most up-to-date advice, the W.H.O. produced its reluctance abundantly obvious, saying the usefulness of experience masks is “not nevertheless supported by high-quality or direct scientific evidence,” but that governments really should persuade mask donning due to “a rising compendium of observational evidence.”
The W.H.O. also offered an exhaustive listing of the potential negatives of putting on 마스크 a mask, including “problems with speaking clearly” and “possible discomfort.”
A review funded via the W.H.O. concluded this 7 days that respirator masks, just like the N95, are much better than surgical masks for overall health treatment staff. In addition, it found that encounter shields, goggles and glasses may well present supplemental safety within the coronavirus.

Whilst experiments have demonstrated that viral R.N.A. is existing inside the air in particular health and fitness treatment settings, “transmission is different, and it hasn't been shown,” she stated.
“It is disappointing that the W.H.O. is dismissing that most recent proof that N95s are significantly simpler than surgical masks in preserving overall health care personnel from Covid-19 publicity,” reported David Michaels, an epidemiologist at George Washington University who headed the Occupational Basic safety and Health and fitness Administration over the Obama administration.
“If the issue is the shortage of N95s, the W.H.O. should really admit that rather than faux that health care masks are equally successful.”
