Which organization primarily manages pests that transmit diseases?

The correct choice is identified as the vector control agency, which is specifically tasked with managing and preventing pest populations that are known to transmit diseases to humans and other animals. Vector control agencies focus on organisms such as mosquitoes, ticks, and rodents, which can carry a variety of pathogens causing diseases like West Nile virus, Lyme disease, and hantavirus.

These agencies implement various strategies for disease prevention, including surveillance of vector populations, public education on controlling vectors, and direct interventions such as insecticide spraying or habitat modification. They are essential in addressing public health threats posed by vectors, ensuring communities are protected from the potential outbreaks of vector-borne diseases.

Other organizations mentioned, while they may have overlapping responsibilities, do not primarily focus on disease-transmitting pests. Pest control agencies generally manage a broader range of pest species, including structural pests that do not transmit diseases. Environmental protection agencies are involved in protecting ecosystems and may indirectly affect vector control through regulations, but they are not solely dedicated to managing disease vectors. Public health departments monitor health trends and provide education, but they may rely on vector control agencies for specific actions aimed at controlling disease transmission from pests.
