Second Avian Influenza Case Confirmed in Hawaii

Hawaii has confirmed a second case of highly pathogenic avian influenza (HPAI) in a wild duck on Oahu’s North Shore, following the first detection at a bird sanctuary on November 15, 2024. The hybrid duck, part mallard, was one of ten sampled, prompting ongoing surveillance by multiple agencies including USDA-APHIS-Wildlife Services and the U.S. Fish and Wildlife Service. State Veterinarian Isaac Maeda warned that the virus could spread through the wild bird population and urged poultry and pet bird owners to prevent contact with wild birds. A total of 70 birds have been euthanized due to the outbreak, which is believed to have been introduced via migratory birds along the Pacific flyway. Although avian influenza in humans is rare, health officials advise vigilance for potential symptoms. Residents are encouraged to report sick or dead birds while maintaining precautions when handling any deceased wildlife.
