It added that the “risk of transmission is greatest within three to six feet of an infectious source???, where the most concentration of the very fine particles occurs.“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,??? the statement read.The American medical agency said that people release respiratory fluids during various activities, including exhalation through quiet breathing, speaking, exercise, singing, coughing and sneezing. It is these droplets that carry and transmit the virus.“The largest droplets settle out of the air rapidly, within seconds to minutes,??? the statement said. “The smallest very fine droplets, and aerosol particles formed when these fine droplets rapidly dry, are small enough that they can remain suspended in the air for minutes to...Read more
