A group of 239 scientists plans to urge the World Health Organization to more seriously consider the threat that the novel coronavirus may be spread by microscopic particles in the air.
The New York Times first reported Saturday that an international coalition of researchers will publish an open letter asking WHO to address airborne transmission of the virus. The scientists say there is growing evidence tiny aerosols can linger in the air indoors and result in new infections.
