Human Benefits of Animal Interventions for Zoonosis Control

TLDR

Industrialized nations have contained recent zoonotic outbreaks, but resource‑limited countries struggle, underscoring the need to target animal reservoirs for control. The study examines whether livestock interventions actually benefit public health sectors. Cross‑sectoral assessments of mass vaccination programs in Mongolia and Chad evaluate human and animal health outcomes from a societal economic standpoint. The analyses show that animal‑sector interventions yield net societal savings, offering an economic rationale that could spur multi‑sector control strategies in resource‑limited settings.

Abstract

Abstract Although industrialized countries have been able to contain recent outbreaks of zoonotic diseases, many resource-limited and transitioning countries have not been able to react adequately. The key for controlling zoonoses such as rabies, echinococcosis, and brucellosis is to focus on the animal reservoir. In this respect, ministries of health question whether the public health sector really benefits from interventions for livestock. Cross-sectoral assessments of interventions such as mass vaccination for brucellosis in Mongolia or vaccination of dogs for rabies in Chad consider human and animal health sectors from a societal economic perspective. Combining the total societal benefits, the intervention in the animal sector saves money and provides the economic argument, which opens new approaches for the control of zoonoses in resource-limited countries through contributions from multiple sectors.
