Which term defines a disease that can be transmitted from animals to humans?

• A. Encephalitis
• B. A trap that targets egg-laying mosquitoes
• C. Landing Rate Count
• D. Zoonotic Disease

Answer: (D)

Zoonotic disease describes a disease that can be transmitted from animals to humans. Pathogens—like viruses, bacteria, or parasites—can live in animal populations and spill over to people through direct contact, eating or handling infected animals, or via vectors such as mosquitoes. In mosquito control, recognizing zoonoses helps explain why human risk often involves wildlife and vector activity working together, as with West Nile virus traveling from birds to humans through mosquitoes. Encephalitis, while a brain inflammation, is a type of disease rather than the transmission category. A trap and a Landing Rate Count are tools or methods used in surveillance, not diseases. So the term that fits the description is zoonotic disease.
