Which of the following is NOT listed as a medical transmission route?

• A. fecal-oral
• B. respiratory
• C. direct contact
• D. vector borne

Answer: (C)

This question tests how medical transmission routes are defined in this material. In that framework, the routes explicitly listed are fecal-oral, respiratory, and vector-borne. Direct contact, while a real way infections spread, is not included in that particular listing of medical transmission routes. Therefore it is the option that is NOT listed as a medical transmission route, making it the best choice. The other options are standard routes that are indeed listed, which is why they aren’t the correct answer in this context. Remember that direct contact is still a common transmission pathway in many settings, but this item uses a specific categorization.
