Description:

Updated May 7, 2021

The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory fluids carrying infectious virus. Exposure occurs in three principal ways: (1) inhalation of very fine respiratory droplets and aerosol particles, (2) deposition of respiratory droplets and particles on exposed mucous membranes in the mouth, nose, or eye by direct splashes and sprays, and (3) touching mucous membranes with hands that have been soiled either directly by virus-containing respiratory fluids or indirectly by touching surfaces with virus on them.

Content Notes:

SARS-CoV-2 is transmitted by exposure to infectious respiratory fluids -- The risk of SARS-CoV-2 infection varies according to the amount of virus to which a person is exposed -- Transmission of SARS-CoV-2 from inhalation virus in the air farther than six feet from an infectious source can occur -- Prevention of COVID-19 transmission -- References.
