Which of the following would be considered transmission routes for infection: I. droplet, II. indirect contact, III. direct contact, IV. Airborne.

Answer

The correct answer is d. I, II, III, IV. In infection control, there are several primary modes of transmission: 1. Direct contact involves physical touch between an infected person and a susceptible person (e.g., skin-to-skin touch). 2. Indirect contact occurs when an infectious agent is transferred via an intermediate object, person, or surface (fomite). 3. Droplet transmission involves large respiratory particles that travel short distances (usually less than 3-6 feet) through coughing or sneezing. 4. Airborne transmission involves small particles that remain suspended in the air for long periods and can be inhaled over longer distances. All four mentioned options are recognized routes for the spread of infectious diseases.
