Early warning for livestock disease spread

Veterinary authorities detect outbreaks late because farm reports are sparse and delayed.

Problem

Symptoms are under-reported; by the time labs confirm, animals have moved between farms.

Farmers call vets; samples go to labs; authorities issue notices after confirmation.

Larger culls, trade restrictions, and rural income shocks.

Models fusing abattoir findings, weather, and movement permits can raise earlier risk scores by region.

Data sharing across agencies; false alarms costly.

Stigmatizing regions incorrectly; farmer distrust.

Mandatory reporting and sentinel farms.

Compliance gaps; sentinels miss silent spread.
