What does it mean when Sars-CoV-2 is airborne, what do we do?
What are the causes for Sars-CoV-2?
Sars-CoV-2 is a virus that causes Covid-19 through exposure of respiratory droplets carrying infectious virus. These droplets can be produced during exhalation, breathing, speaking, singing, sneezing & coughing.
Large droplets that are visible fall out of air rapidly within seconds to minutes while close to the source, Smaller droplets are formed when small droplets dry quickly in airstream, can remain suspended for many minutes to hours and travel far from the source on air currents.
Prevent the spread of Sars-CoV-2: Social Distancing, use of masks in the community, hand hygiene, and surface cleaning and disinfections, Ventilation and Avoidance of crowded indoor spaces are relevant for enclosed spaces.
Airborne transmission of Sars-CoV-2 can occur under special circumstances
Pathogens are mainly transmitted through close contact (i.e., contact transmission and droplet transmission) can sometimes also be spread via airborne transmission under special circumstances. SARS-CoV-2 have been transmitted over long distances or times. These transmission events appear uncommon and have typically involved the presence of an infectious person producing respiratory droplets for an extended time(>30 minutes to multiple hours) in an enclosed space. Enough virus was present in the space to cause infections in people who were more than 6 feet away or who passed through that space soon after. Circumstances under which airborne transmission of SARS-CoV-2 appears to have occurred include:
Enclosed Spaces, Prolonged exposure to respiratory particles, Inadequate ventilation or air handling.
