Which statement best defines a droplet infection?

• A. The transfer of pathogens via a fine spray emitted from an infected person
• B. Inhalation of aerosols over long distance
• C. Transmission through contaminated water
• D. Transmission through skin contact

Answer: (A)

Droplet infection spreads when larger respiratory droplets are expelled from an infected person—such as by coughing, sneezing, or talking—and reach the mucous membranes of a nearby person. These droplets are relatively big, so they don’t travel far and tend to deposit within a short distance, typically onto the nose, mouth, or eyes of someone nearby. This is different from airborne transmission, where tiny particles (aerosols) stay suspended in the air and can travel longer distances. Transmission through contaminated water describes a waterborne route, and transmission through skin contact describes contact transmission from touching contaminated surfaces or people. So the statement that describes a transfer of pathogens via a fine spray emitted from an infected person best captures droplet spread.
