Highly pathogenic avian influenza (HPAI) Type A Subtype H5N9 has been confirmed for the first time in the Philippines, according to the Department of Agriculture-Bureau of Animal Industry (DA-BAI).

On April 30, 2025, the BAI-Animal Disease Diagnosis and Reference Laboratory reported positive results from duck samples collected during a routine surveillance in Camaligan, Camarines Sur by DA Regional Field Office Bicol.
H5N9 avian influenza is highly pathogenic only among birds but not in humans, according to BAI officials.
The remaining ducks in the affected farms in the area were culled and disposed. Today, the DA-Bicol region implemented intensive surveillance within the one-kilometer quarantine zone alongside close monitoring and disinfection to prevent the spread of HPAI or bird flu.
The BAI, meanwhile, urged the public to remain vigilant and report unusual poultry deaths or sickness to the nearest local authorities.
