The World Health Organization (WHO) is preparing a scientific brief to address continually emerging evidence on transmission of COVID-19 and says that airborne transmission of the virus can occur in 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.
As with everything we have learned to date regarding COVID-19, it is changing daily. There are new studies being conducted, research being done and new preventive interventions being trialed. Continue to rely on the experts, work with your local health departments, and maintain current practices in your centers. Stay well, stay safe, and stay tuned!
