What are the three areas of One Health?

• A. Humans, Animals, Environment
• B. Humans, Plants, Environment
• C. Humans, Animals, Water
• D. Humans, Animals, Climate

Answer: (A)

One Health emphasizes how human health is connected to the health of animals and the environment. The three areas are humans, animals, and environment. The environment encompasses air, water, soil, ecosystems, and all living and nonliving factors that influence health, framing how changes in one part of the system can affect the others. This perspective helps explain the emergence and spread of diseases, how environmental conditions shape nutrition and disease risk, and issues like antimicrobial resistance that cross species boundaries. Plants aren’t treated as a separate pillar in this framework, and water or climate are components within the environment rather than distinct domains.
