Covid-19: Scientists urge WHO to admit virus can spread in air

A group of scientists have urged the World Health Organization (WHO) and others to acknowledge that Covid-19 can spread in the air and suggested bringing a change that could alter some of the current measures being taken to stop the pandemic.

"Beyond any reasonable doubt that viruses are released during exhalation, talking and coughing in microdroplets small enough to remain aloft in the air," said two scientists from Australia and the US in a letter published this week in the journal Clinical Infectious Diseases.

People in certain indoor conditions could be at greater risk of being infected than was previously thought, they said.

The WHO has long maintained that Covid-19 is spread via larger respiratory droplets, most often when people cough or sneeze, that fall to the ground. It has dismissed the possibility of airborne transmission, except for certain high-risk medical procedures, like when patients are first put on breathing machines.

In a statement on Monday, the UN health agency said it was aware of the article and was reviewing it with technical experts.

WHO has been criticised in recent weeks and months for its seeming divergence from the scientific the community.
