What is the term for the vehicle by which pathogens move from place to place or person to person?

• A. Carrier
• B. Reservoir
• C. Fomite
• D. Vector

Answer: (D)

Understanding how pathogens move between hosts hinges on the transmission vehicle. A vector is a living organism that actively transmits pathogens from one host to another, often by biting or transferring the agent into the new host. This makes the vector the vehicle that carries the pathogen between people or places, such as mosquitoes transmitting malaria or dengue, or ticks spreading Lyme disease. In contrast, a carrier is a person or animal that harbors the pathogen and may spread it but is not the vehicle itself; a reservoir is the habitat in which a pathogen normally lives and multiplies; a fomite is a nonliving object that can carry pathogens on its surface. Therefore, the term that describes the vehicle moving pathogens is vector.
