The World Health Organization is reviewing a report that suggests WHO needs to update its advice on the novel coronavirus, after scientists to the New York Times there is evidence the virus can spread by tiny particles in the air.
WHO claims the COVID-19 disease spreads mainly through small droplets, which are expelled from the nose and mouth when an infected person breathes them out, coughs, speaks, sneezes, or laughs, and quickly sink to the ground.
In an open letter to WHO, 239 scientists from 32 countries outlined the evidence they say shows that smaller exhaled particles can infect people who inhale them.
Due to those smaller particles being able to linger in the air longer, the scientists are urging WHO to update its guidance.
The scientists do plan on publishing their findings in a scientific journal this week.
The extent to which the coronavirus can spread by airborne or aerosol route, as opposed to larger droplets in coughs and sneezes, remains in dispute.
