…health care settings where specific medical procedures, called aerosol generating procedures, generate very small droplets called aerosols. Some outbreak reports related to indoor crowded spaces have suggested the possibility of aerosol transmission, combined with droplet transmission, for example, during choir practice, in restaurants or in fitness classes,” according to the World Health Organization.
“Ventilation is the key control point for an airborne virus. Based on multiple studies done by the authors, we believe that optimized ventilation is the way to move forward, removing the virus from the air before people inhale it. We think that’s one of the main ways it’s transmitted,” Dr. Julian Tang, an author of a paper on COVID-19 spread, told USA Today.
Since not everyone has the option to stay outside, the American Society of Heating, Refrigerating and Air-Conditioning Engineers is figuring out ways to make indoor spaces safer.
The key is to lower the concentration of possibly infected particles in the air, the Society stated.
