Which of the following is an example of vectorborne transmission?

Vectorborne transmission refers to the spread of infectious agents through vectors, which are living organisms that carry and transmit pathogens to humans or other animals. Mosquitoes, for example, are common vectors for diseases such as malaria, dengue fever, and Zika virus. When a mosquito bites a person, it can introduce the pathogens it carries directly into the person's bloodstream, leading to infection.

In contrast, contact with infected blood can occur through blood transfusions or sharing needles, which is a different mode of transmission. Eating contaminated food is related to foodborne transmission, where pathogens enter the body via the gastrointestinal tract. Sharing personal items might facilitate the spread of infections, but typically through indirect contact and not through a vector. Understanding these distinctions is crucial for recognizing different infection control measures necessary for various transmission routes.
