What is direct transmission in the context of infection control?

Direct transmission refers specifically to the transmission of infectious agents through immediate physical contact between an infected person and a susceptible host. This includes droplet transmission, where pathogens are expelled into the air in droplets during activities such as coughing or sneezing and can directly land on mucous membranes of those nearby, as well as direct contact transmission, where an infected individual touches another person.

Understanding this concept is crucial in infection control because recognizing how infections spread can inform effective prevention measures, such as encouraging hand hygiene and the use of masks when close to others. Knowing that direct contact and droplet spread are primary means of transmission helps in taking the necessary precautions to mitigate the risk of spreading infections in healthcare settings as well as in everyday life. The other options describe alternative modes of infection transmission or practices that may not involve direct interaction with an infected individual, highlighting the distinct nature of direct transmission.
