Hawai'i's North Shore has become the latest point of interest as the National Veterinary Services Laboratories confirmed the presence of highly pathogenic avian influenza in a wild duck, stirring concerns among wildlife and agricultural communities. According to a statement released by the USDA-Animal and Plant Health Inspection Service, Wildlife Services, this is the second confirmed case of avian influenza in the state, following a previous incident at a Wahiawā bird sanctuary, as per the Department of Agriculture.
The infected bird, identified as a part mallard hybrid, was discovered amongst a group of 10 ducks collected for testing from the area. In light of these findings, authorities have intensified surveillance efforts alongside multiple agencies. This follows a somber event on November 15, when 70 birds had to be swiftly depopulated to prevent further spread of the disease. State Veterinarian Isaac Maeda, DVM, underscored the urgency of the situation by stating, "This detection of HPAI is an indication that the virus may be spread on O‘ahu via the wild bird population." He strongly urged poultry, backyard and pet bird owners to avoid contact between their birds and wild populations, as mentioned by the Department of Agriculture.
Avian influenza's impact is severe, with symptoms ranging from sudden death to respiratory distress, and there are no known treatments for highly pathogenic avian influenza. The specter of transmission is worrisome for both poultry operations and wild bird ecosystems. The Centers for Disease Control and Prevention reassures that most common songbirds do not carry strains dangerous to poultry or humans, but the disease remains a serious concern for birds of the waterfowl variety that can silently harbor the virus and infect others, as reported by the Department of Agriculture.
Biosecurity for birds is paramount, with the U.S. Department of Agriculture offering detailed resources to assist flock owners in defending their birds against avian influenza. The agencies have made available information on how to properly increase safety measures. Anyone encountering sick or dead birds is advised not to directly touch them without proper protective gear and is encouraged to contact HDOA’s Division of Animal Industry for assistance. Poultry and bird owners suspecting a high mortality rate in their flocks should promptly reach out to their veterinarians and authorities for guidance.
For further information on avian influenza and recommended preventive measures, the public can refer to resources provided by the HDOA, the USDA, and the CDC. The HDOA’s webpage on animal disease control directs poultry owners and the public to literature on increased biosecurity measures and guidance on handling dead birds safely, while emphasizing the importance of reporting unusual bird deaths to state officials.
