Which route is listed as a medical transmission route?

• A. fecal-oral
• B. air-borne
• C. direct contact
• D. water-borne

Answer: (A)

In healthcare, infection transmission routes describe how pathogens move from one person to another, and fecal-oral is a major route highlighted in medical hygiene practices. Fecal-oral transmission happens when organisms shed in feces contaminate food, water, or surfaces, and are then ingested, often via unwashed hands. This pathway is a key focus in medical settings because simple lapses in hand hygiene, food handling, or sanitation can quickly spread infections among patients and staff.

The other options are real transmission routes as well, but they are described differently in medical contexts: air-borne involves small particles inhaled into the lungs, direct contact requires physical interaction with an infected person or contaminated surface, and water-borne involves ingesting contaminated water. The item points to fecal-oral as the route emphasized in medical transmission lists, reflecting the strong emphasis on hygiene and sanitation to prevent spread.
