The advisor recalled that the W.H.O. workers members in his nation had been the one ones to go with out masks after the federal government there endorsed them.
Many consultants stated the W.H.O. ought to embrace what some known as a “precautionary principle” and others known as “needs and values” — the concept that even with out definitive proof, the company ought to assume the worst of the virus, apply frequent sense and advocate the most effective safety doable.
“There is no incontrovertible proof that SARS-CoV-2 travels or is transmitted significantly by aerosols, but there is absolutely no evidence that it’s not,” stated Dr. Trish Greenhalgh, a major care physician on the University of Oxford in Britain.

After all, the W.H.O. appears prepared to simply accept with out a lot proof the concept that the virus could also be transmitted from surfaces, she and different researchers famous, whilst different well being companies have stepped again emphasizing this route.
“I agree that fomite transmission is not directly demonstrated for this virus,” Dr. Allegranzi, the W.H.O.’s technical lead on an infection management, stated, referring to things which may be infectious. “But it is well known that other coronaviruses and respiratory viruses are transmitted, and demonstrated to be transmitted, by contact with fomite.”
The company additionally should contemplate the wants of all its member nations, together with these with restricted sources, and ensure its suggestions are tempered by “availability, feasibility, compliance, resource implications,” she stated.
