LONDON – More than 200 scientists have asked the World Health Organization (WHO) and others to recognize that the coronavirus can spread through the air — a change that could alter some of the measures being taken currently to stop the pandemic.
In a letter published this week in the journal Clinical Infectious Diseases, two scientists from Australia and the United States wrote that studies have shown "beyond reasonable doubt that viruses are released by exhaling, speaking and cough with droplets small enough to stay floating in the air. " That means that people in some closed places may be at greater risk of being infected than previously thought.
The WHO has long noted that Covid-19 spreads through larger droplets by breathing, more often when people cough or sneeze, they fall to the floor. It has ruled out the possibility of airborne transmission, except for certain high-risk medical procedures, such as when patients are hooked up to respirators.
In a statement Monday, the UN health agency said that she was aware of the article and discussed it with technical experts.
The WHO has been criticized in recent weeks and months for its apparent divergence from the scientific community. For months, the organization refused to recommend the use of masks, in part because of supply concerns, and also goes on to say that the transmission of the Covid-19 from asymptomatic people is “unusual.”
The letter received support from 239 scientists from a variety of fields. He claims that the issue of whether or not Covid-19 is transmitted by air is of "extreme importance" since many countries stopped restrictive quarantine measures.
The authors cited previous studies suggesting that germs closely related to the new Viruses are spread through airborne transmission.
"There is every reason to expect" that the coronavirus will behave similarly, they said. They also cited the case of a spread during a choir practice in Washington state and an investigation into a poorly ventilated restaurant in Guangzhou, China, each of which increased the chance of infection through tiny droplets in the air. .
