COVID: AIRBORNE OR DROPLET?
T
here have been a few COVID-19 outbreaks in which transmission occurred in a way that suggests it can spread as an aerosol, a light particle that can stay in the air for hours. Both the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) have thus far not definitively stated that COVID-19 is spread through airborne transmission. In July, after 239 scientists called on the agency to revise its position, the WHO did update its recommendation, saying in part: "short-range aerosol transmission, particularly in specific indoor locations, such as crowded and inadequately
ventilated spaces over a prolonged period of time with infected persons cannot be ruled out." Droplet diseases (including strep throat, whooping cough, the flu, and the common cold) travel on respiratory droplets released with coughs, sneezes, and talking. Because of their size compared to air, they usually fall down to the ground and other surfaces quickly and can stay infectious for a long time (several hours for influenza and cold viruses). Airborne diseases (which includes measles, chickenpox, and tuberculosis) are spread on small aerosols that are typically produced by evaporation from respiratory
droplets. They can float in the air for minutes to hours. Regardless of how the virus that causes COVID-19 travels, wearing a mask and socially distancing have been shown to reduce its spread. If the virus that causes COVID-19 is airborne and spreads through small aerosols, additional caution should be taken in indoor spaces with poor ventilation, where the virus may linger in the air, increasing your chances for infection.
