Hundreds of scientists have asked the World Health Organization (WHO) to revise its recommendation for the novel coronavirus pandemic, after they discovered new evidence suggesting that air-borne smaller particles of the virus can infect people.
The WHO had disclosed that the coronavirus disease spreads primarily from person to person through small droplets from the nose or mouth, which are discharged when a person with the coronavirus disease coughs, sneezes or speaks.
According to the scientists whether the virus is carried by large droplets that zoom through the air after a sneeze or by much smaller exhaled droplets that may move quietly through the length of a room, the coronavirus is borne through air and can infect people when inhaled.
Researchers plan to publish in a scientific journal next week, an open letter to WHO by 239 scientists in 32 countries, where they outlined the evidence showing that smaller particles can infect people.
However, the United Nations health agency has said that the report from the scientists that the virus is airborne was not convincing.
According to the WHO technical lead for Infection Prevention and Control, Dr Benedetta Allegranzi, ‘’Especially in the last couple of months, we have been stating several times that we consider airborne transmission as possible but certainly not supported by solid or even clear evidence.”
It can be recalled that WHO said over the weekend that it was stopping its trials of the malaria drug hydroxychloroquine and combination HIV drug lopinavir/ritonavir on hospitalized patients with the coronavirus disease after they failed to reduce the death rate.
The setback came as the WHO reported more than 200,000 new cases of the disease globally, the first time in a single day.
