State responds to 2nd confirmed case of avian influenza in Hawaii - Honolulu Star-Advertiser

On November 14, 2025, Hawaii officials reported the second confirmed case of highly pathogenic avian influenza H5N1 in a migratory duck, specifically the Northern pintail (koloa mapu), found along the Wailea shoreline in Maui. This case marks the first detection of the H5N1 virus on the island, following earlier detections in Central Oahu and on the University of Hawaii’s Manoa campus. The bird was tested and confirmed for the H5N1 strain by the National Veterinary Services Laboratories. H5N1 is known to be a highly infectious and often lethal subtype of influenza A that primarily affects birds while having the potential to be transmitted to humans. Officials state that the overall risk of infection to humans and poultry remains low and do not recommend any restrictions on outdoor activities based on current data. As part of their response, state departments are continuing to monitor public health, poultry operations, and wild bird populations. To prevent potential transmission, the public is advised to avoid contact with sick or dead birds, and to report any unusual wildlife illnesses to the relevant authorities. The article emphasizes the importance of vigilance during the migratory bird season in Hawaii, as these birds can carry various diseases.
