What type of transmission occurs when respiratory droplets travel through the air?

Droplet transmission is a mode of infection transmission that occurs when respiratory droplets, often produced by coughing, sneezing, or talking, travel through the air and come into contact with the mucous membranes of a susceptible individual, such as the eyes, nose, or mouth. These droplets typically fall to the ground within a short distance, usually less than six feet, which differentiates droplet transmission from airborne transmission, where infectious agents can remain suspended in the air for longer periods and travel greater distances.

This type of transmission is significant in the spread of various respiratory infections, including influenza and COVID-19. Understanding droplet transmission is essential for implementing appropriate infection control measures, such as wearing masks and maintaining physical distance, to reduce the risk of spreading pathogens that are transmitted via respiratory droplets.
