From spill-over signal to validated assay: zoonotic surveillance that survives quiet years
Key takeaways
Zoonotic surveillance capacity is a sustainment problem, not a procurement event: few well-instrumented sentinel sites, portable assay menus, dated competency runs through quiet years, and escalation paths agreed before any signal exists.
- Prefer few sentinel sites with strict protocols over broad, shallow networks.
- Choose portable assay menus — lyophilised formats, open platforms, multi-matrix extraction.
- Schedule competency runs on characterised material; an unrun assay is not validated capacity.
- Write signal definitions and escalation paths before the season, not during it.

FAQ
Common questions
Why focus on zoonoses for laboratory surveillance?
Because the majority of emerging infectious diseases originate in animals. WHO maintains a zoonoses priority list precisely because early laboratory detection at the human-animal interface changes outbreak outcomes.
How do you keep assays validated when there are few positive samples?
Through scheduled competency runs on characterised material — inactivated controls, synthetic targets, or panel exchanges with reference laboratories — documented like any performance verification.
What should surveillance procurement optimise for?
Portability and sustainability: reagent formats that tolerate field conditions, instruments the routine bench can maintain, lot sizes matched to the competency calendar, and service contracts with local response commitments.
Who should receive an unusual surveillance signal?
Whoever your programme designates in writing before the season — typically the public-health authority epidemiologist and the designated reference laboratory, within a defined reporting window.
