Prolonged right after most nations urged their citizens to have on 마스크 masks, and following months of hand-wringing about the standard of the proof obtainable, the World Overall health Firm on Friday endorsed using experience masks by the public to scale back transmission in the coronavirus.
Considering that the start in the pandemic, amazingly, the W.H.O. had refused to endorse masks. The announcement was very long overdue, critics mentioned, as masks are a simple and cheap preventive evaluate.
Even in its latest steering, the W.H.O. created its reluctance abundantly obvious, expressing the usefulness of face masks is “not yet supported by top quality or direct scientific proof,” but that governments need to stimulate mask sporting thanks to “a rising compendium of observational evidence.”
The W.H.O. also supplied an exhaustive listing of the probable drawbacks of putting on a mask, like “issues with communicating Obviously” and “opportunity distress.”
A examine funded via the W.H.O. concluded this 7 days that respirator masks, like the N95, are much better than surgical masks for health treatment personnel. Additionally, it uncovered that confront shields, goggles and Eyeglasses could offer you further defense with the coronavirus.
Although the W.H.O. did not budge from its previous suggestions for medical workers, expressing that respirator masks are only desired if these kinds of staff are involved in techniques that generate virus-laden aerosols — droplets smaller than 5 microns.
Besides Individuals conditions, transmission in the virus up to now has only been shown for more substantial droplets and by Make contact with, claimed Dr. Benedetta Allegranzi, an infectious illness specialist and specialized guide for that W.H.O.
Whilst reports have shown that viral R.N.A. is existing from the air in specified well being treatment settings, “transmission http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/마스크 is different, and it hasn't been demonstrated,” she stated.
“It's disappointing the W.H.O. is dismissing that most current evidence that N95s are far more practical than surgical masks in protecting well being care workers from Covid-19 exposure,” mentioned David Michaels, an epidemiologist at George Washington University who headed the Occupational Safety and Wellbeing Administration throughout the Obama administration.
“If the issue would be the scarcity of N95s, the W.H.O. should really acknowledge that and never pretend that clinical masks are Similarly efficient.”
