THE Bureau of Animal Industry (BAI) has confirmed the detection of the country's first case of a new strain of bird flu, specifically High Pathogenicity Avian Influenza (HPAI) Type A Subtype H5N9, in Camaligan, Camarines Sur.

On April 30, 2025, the BAI-Animal Disease Diagnosis and Reference Laboratory (BAI-ADDRL) reported positive results from duck samples collected during a routine surveillance by DA Regional Field Office V (DA-RFO V).

Subtype H5N9, while highly pathogenic in birds, poses a low risk to humans based on current global assessments.​..
