What distance typically defines close contact for droplet transmission?

Droplet transmission occurs when respiratory droplets from an infected person are expelled into the air, typically during activities such as coughing, sneezing, or talking. The most widely acknowledged standard for defining close contact regarding droplet transmission is a distance of less than 2 meters, or approximately 6 feet. This distance is based on research that indicates droplets can travel this far before gravity causes them to settle on surfaces.

Maintaining a distance greater than 2 meters is often recommended in order to reduce the risk of droplet transmission, especially in healthcare settings or during outbreaks of illnesses spread in this manner. This guideline helps protect both healthcare providers and patients by minimizing the likelihood of exposure to respiratory droplets.
