Why is pathogen discovery across species important in One Health?

• A. Identifying novel pathogens across species to understand spillover risk and inform surveillance and response strategies.
• B. It has no role in One Health.
• C. It is only for academic curiosity.
• D. It replaces vaccination programs.

Answer: (A)

Recognizing pathogens across species is central to One Health because it shows how diseases can move between animals, humans, and the environment. By identifying novel pathogens in animals or wildlife, we gain early insight into which agents could spill over and under what conditions this might happen. That knowledge lets us design smarter surveillance—targeting high‑risk species and settings, choosing appropriate tests, and monitoring for changes in ecology or behavior that raise contact. It also underpins rapid, proactive response planning, including targeted biosecurity, wildlife and livestock management, and deploying vaccines or other interventions when available so they can blunt outbreaks before humans are affected. This approach is practical and preventive, not just academic, and it complements vaccination programs by guiding where and when to apply them and by identifying threats before they cause illness.
