Zoonotic Disease Wildlife Surveillance Welfare

Wildlife disease surveillance serves both animal welfare and public health goals, requiring sampling methods that minimise harm to individual animals while generating population-level data.

Key Facts

Wildlife serve as reservoirs for numerous zoonotic diseases including rabies, avian influenza, and Lyme disease
Surveillance sampling requires capture and handling of wild animals, imposing welfare costs
Minimally invasive sampling including faecal and environmental DNA reduces handling requirements
Sentinel surveillance using animals that have died from other causes provides disease data without capture
One Health approaches integrate wildlife, livestock, and human health surveillance in unified systems

Welfare Considerations

Wildlife disease surveillance creates a welfare dilemma: the capture and sampling required to monitor disease imposes real costs on individual animals, but the information generated protects both wild animal populations and human health. Minimising surveillance welfare costs while maintaining data quality requires investment in low-invasive sampling methods: environmental DNA, passive sentinel systems, and opportunistic sampling of animals that require management for other reasons. When capture is necessary, standardised welfare protocols — rapid processing, experienced handlers, monitoring for capture myopathy — reduce harm. The One Health framework that integrates wildlife, livestock, and human health surveillance delivers maximum public health benefit per unit of wildlife welfare cost by targeting surveillance intelligently.
