What best describes One Health security?

• A. An isolated approach to animal health.
• B. An integrated approach to prevent and respond to cross-species health threats through coordinated surveillance, governance, and rapid response.
• C. Only about pandemic response.
• D. Focused solely on human health.

Answer: (B)

One Health security is about an integrated approach that brings together human, animal, and environmental health to prevent and respond to threats that move across species. It relies on coordinated surveillance across sectors so warning signs in animals or the environment can inform human health actions, shared governance structures to align priorities and resources, and rapid, collaborative response when a cross-species risk is detected. This perspective recognizes that diseases don’t respect species boundaries and that actions in one domain can prevent problems in another, making prevention and response more effective.

That’s why this option is the best fit: it captures the need for collaboration, cross-sector surveillance, and timely governance-driven action to address threats that span humans, animals, and the environment. By contrast, an isolated approach misses the cross-species nature of many threats; limiting the focus to pandemics or to human health alone ignores the animal and environmental drivers and the value of joint, proactive measures.
