Which disease category has a reservoir in animal populations?

• A. Anthroponoses
• B. Zoonoses
• C. Epidemic
• D. Pandemic

Answer: (B)

Zoonoses are diseases that have an animal reservoir, meaning the pathogen can persist in animal populations and spill over to humans. This animal reservoir is what maintains the pathogen in nature and enables occasional transmission to people through contact or vectors. Anthroponoses, by contrast, are diseases managed and sustained primarily in human populations, with humans as the main reservoir. Epidemic and pandemic describe outbreaks in terms of how widely and rapidly a disease spreads, not where the pathogen is maintained. An example of a zoonosis is rabies, which circulates in wildlife and can be transmitted to humans.
