ASF in numbers

Zoning and cases as of 22 October 2026: how the data is updated

Cases, monthly figures and recoveries come from DA-BAI’s latest status update. Zones come from DA-BAI’s latest zoning status.

About these figures

Cases are counted the way DA-BAI counts them: barangays with active cases, not numbers of pigs.

The status update and the zoning status are published separately, each about every two weeks, so a town can have cases before its zone is raised, or keep a red zone after its cases clear. Both are shown as published. How the data is processed
