Vector-borne transmission refers to pathogens spread by which means?

• A. Direct
• B. Vehicle
• C. Vector-borne
• D. Parenteral

Answer: (C)

Vector-borne transmission occurs when a living organism, typically an arthropod like a mosquito, tick, or flea, carries a pathogen from one host to another. The vector becomes infected when feeding on an affected host and then transmits the pathogen to a new host, usually by biting. This is different from direct transmission, which happens through person-to-person contact without an intermediate carrier; vehicle transmission, which uses inanimate objects or substances to carry the pathogen; and parenteral transmission, which introduces the pathogen directly through the skin via puncture or injection. Recognizing this mode helps explain why certain infections are tied to vector exposure and why protective measures against vectors matter in public health, while the phlebotomy focus remains on preventing exposure to blood and ensuring safe needle handling.
