A group of researchers, which included 239 specialists from 32 countries, prepared an open letter to the world health organization (who), which urges to state the obvious, according to some people, the fact that the new coronavirus can be transmitted by airborne droplets, long lingering in the air.
This writes the newspaper The New York Times.
As the material, this group of scientists believes that the virus-containing tiny droplets of liquid that are allocated when the infected cough or sneeze can stay in the air longer than suggested by who.
The researchers say that the organization should review some of his recommendations.
Who saysthat the virus is spread through respiratory droplets when coughing and sneezing of an infected, but they quickly settle because of its size. If it turns out that the virus is spread by airborne droplets, the “consequences in terms of containment would be substantial, “writes the NYT.
New preventive measures include wearing masks in the room “even subject to social distancing”, and medical staff must wear masks of N95 type “to filter even the smallest respiratory droplets when working with coronavirus patients”.
In addition, it is necessary to revise the design of ventilation systems to “to minimize recirculation of the air.” The article said that after studying the internal correspondence of the who and an interview with 20 scientists, including who consultants, the picture that emerges is that, “despite good intentions”, organization is “not going up with the science.” The NYT writes that the recent surge in the number of victims upon the resumption of companies and office activities confirms “what many scientists say several months, namely that the virus builds up in the indoor air, infecting those who are close”.
The newspaper quotes the comment of the representative who Benedetti of Allegranzi.
“We have stated several times, particularly in the last couple of months that we consider the transmission of airborne droplets possible, but of course it is not supported by solid or even clear evidence, she added. — On this issue are actively disputes”, — said the representative of the who.
As notes the edition, it is expected that this open letter will be published next week in a scientific journal. Excerpts from it are not given. The article also did not specify which States and organizations referred to 239 researchers.
The publication presents the opinions of several researchers from Australia, Britain, USA, who noted that who, perhaps, should formally recognize that the coronavirus can be transmitted by airborne droplets. The publication reports that in early April, 36 experts have suggested who to consider.
We will remind that according to official statistics of the who, as of Sunday evening the number of cases of infection with coronavirus in the world for a day has increased by more than 203 thousand, exceeding the 11.1 million. The number of deaths increased by more than 5 thousand and has made more than 528 thousand
Earlier, the “FACTS” wrote that in China revealed a new dangerous strain of influenza virus. From the point of view of genetics it is a combination of avian, swine and human influenza. In the genotype there are traces of the strain that caused the swine flu epidemic in 2009. Potentially new strain could lead to another pandemic.
