The World Health Organization (WHO) is reviewing a report urging it to update guidance on the novel
Coronavirus after more than 200 scientists, in a letter to the health agency, outlined evidence the virus can spread in tiny airborne particles.
Dr. William Hanage, an epidemiologist at the Harvard T.H. Chan School of Public Health, said the report under review at the WHO "makes many reasonable points about the evidence that this mode of transmission can happen, and they should be taken seriously."
