Which statement best summarizes the One Health concept?

• A. It focuses only on human medicine
• B. It involves cooperation among multiple disciplines to address human, animal, and environmental health
• C. It excludes ecologists
• D. It is unrelated to public health

Answer: (B)

One Health is about the interconnection of human, animal, and environmental health and solving health issues through collaboration across many disciplines. The best statement captures this by saying cooperation among multiple disciplines is needed to address all three realms—human health, animal health, and the environment—since risks and solutions in one domain affect the others. In practice, this means veterinarians, doctors, ecologists, epidemiologists, environmental scientists, and policy makers working together to monitor diseases that jump between animals and people, manage antimicrobial resistance, ensure food safety, and protect ecosystems. Focusing only on human medicine ignores the animals and the environments that influence health; excluding ecologists leaves out crucial insight about ecosystems and disease dynamics; and denying a link to public health misses the broader goal of preventing illness and safeguarding communities.
