In an updated guidance on Monday U.S. CDC said that, COVID-19 can spread through the airborne transmission. Centers for Disease Control and Prevention (CDC) Scientific Briefs stated that “Airborne transmission of SARS-CoV-2 (the virus that causes COVID-19) can occur under special circumstances”
According to CDC Pathogens (a bacterium, virus or other microorganism that can cause disease) that are mainly transmitted through close contact (i.e., contact transmission and droplet transmission) can sometimes also be spread via airborne transmission under special circumstances.
Circumstances under which airborne transmission of SARS-CoV-2 appears to have occurred include:
Enclosed spaces within which an infectious person either exposed susceptible people at the same time or to which susceptible people were exposed shortly after the infectious person had left the space.
Prolonged exposure to respiratory particles, often generated with expiratory exertion (e.g., shouting, singing, exercising) that increased the concentration of suspended respiratory droplets in the air space.
Inadequate ventilation or air handling that allowed a build-up of suspended small respiratory droplets and particles.
