Summary
Researchers say their RAVEN AI system can forecast areas at risk of avian influenza outbreaks in Canada, with tests showing stronger results than five established machine-learning methods for both poultry and wild birds. The study used Canadian outbreak records from November 2021 to May 2026 and environmental and satellite-based map data; it reported better performance at a seven-day forecast horizon than at 14 days. The authors caution that uneven wildlife reporting and limits in the model’s testing affect how widely its results can be applied.
