What is the primary transmission method for droplet infection?

The primary transmission method for droplet infection is through breathing in infected respiratory droplets. Droplet infections are caused when an infected person coughs, sneezes, laughs, or talks, releasing droplets that can carry pathogens such as viruses or bacteria. These droplets can be inhaled by people nearby, leading to the transmission of infectious agents, particularly respiratory illnesses.

This mode of transmission is significant because respiratory droplets typically travel only a short distance—usually within about six feet—before settling on surfaces or being inhaled directly by others nearby. This is why maintaining distance and wearing masks can help reduce the spread of respiratory infections during outbreaks. While the other options describe other methods of transmission, they are not relevant to droplet infection specifically.
