Transboundary Emerging and Exotic Animal Disease/ Exotic Animal Disease Practice Exam

What role do vectors play in the transmission of exotic animal diseases?

1. They are responsible for horizontal transmission.

2. They facilitate vaccine distribution.

3. They are key in genetic mutation.

4. They have no role in disease transmission.

The correct answer is: They are responsible for horizontal transmission.

Vectors play a crucial role in the transmission of exotic animal diseases by acting as intermediaries that carry pathogens from one host to another. This process is known as horizontal transmission, where the disease-causing agent is transferred between individuals within a population, rather than being inherited from parent to offspring. In the context of exotic animal diseases, vectors, such as mosquitoes, ticks, and fleas, can harbor various pathogens like viruses, bacteria, and protozoa. When these vectors feed on a susceptible animal, they can transmit the infectious agents, thereby leading to outbreaks of disease that may spread rapidly across regions and populations. This understanding underscores the importance of controlling vectors in managing and preventing outbreaks of exotic diseases, as they can significantly influence the dynamics of disease spread and impact overall animal health. Other options do not accurately capture the critical role that vectors play in disease transmission when considering exotic animal diseases.
