Taking a One Health approach to event-based surveillance. While each zoonotic disease requires a tailored surveillance strategy to ensure a targeted and expedient response, the One Health linkages (shown in teal) may be similar across many different event types. In this generalized zoonotic disease example, event-based surveillance begins with the detection of an “event” or verified signal in red that triggers a response. This event, detected at the community level, is reported to the sub-national (e.g., states, provinces, or jurisdictions), national and international levels from left to right. Results and recommendations are disseminated in the opposite direction (i.e., right to left), with the intention of communicating synthesized results and recommendations back to at-risk communities. See Supplementary Figs. S1–S5 for pathogen-specific examples of event-based surveillance in anthrax, brucellosis, rabies, Rift Valley fever, and zoonotic influenza viruses.
