Droplet transmission is a method of spreading infectious diseases through tiny droplets that are expelled when a person coughs, sneezes, or talks. These droplets can contain viruses or bacteria and can travel short distances, typically up to about six feet. When another person inhales these droplets or they land on their mucous membranes, such as the eyes, nose, or mouth, they can become infected. Common illnesses spread through droplet transmission include influenza, COVID-19, and common colds. To reduce the risk of droplet transmission, health experts recommend practices such as wearing masks, maintaining physical distance, and practicing good hand hygiene.
