Which of the following is an example of a zoonotic disease transmitted by vectors?

Rabies is a prime example of a zoonotic disease transmitted by vectors. Zoonotic diseases are those that can be transmitted between animals and humans. In the case of rabies, the virus is primarily spread through the saliva of infected animals, particularly through bites from rabid mammals such as bats, raccoons, and dogs. This direct transmission from animals to humans highlights the zoonotic nature of the disease.

Understanding rabies involves recognizing that vectors in this context are not just insects but can also include mammals that serve as carriers of the virus. The transmission routes for rabies include bites and scratches from infected animals, which is critical for vector control technicians to consider when dealing with disease management and education.

The other choices—flu, tuberculosis, and hepatitis B—do not primarily involve vector transmission. Influenza is mostly spread through respiratory droplets, tuberculosis is a bacterial infection spread through the air, and hepatitis B is a viral infection transmitted through bodily fluids, not through vectors. Recognizing the specific methods of transmission aids in understanding how to prevent these diseases effectively.
