The recent detection of highly pathogenic avian influenza (HPAI) in Hawaii has raised concerns for the poultry and wild bird populations, but experts assure that there is currently no immediate threat to humans. Axel Lehrer, a professor of tropical medicine and medical microbiology at the University of Hawaii, has stated that the virus has limited ability to spread to humans or mammals, and there have been no reported cases of human-to-human transmission.
The HPAI was first detected in a backyard flock of birds in Wahiawa, believed to have arrived in Hawaii through bird migration via the Pacific flyway. While the virus causes severe illness with a high mortality rate among birds, the symptoms in humans are typically mild, including conjunctivitis and respiratory symptoms.
Authorities have been tracking and responding to the outbreak since 2022, with the Hawaii Department of Agriculture (HDOA) working closely with the Department of Health (DOH) and veterinary staff at the University of Hawaii to educate and outreach to poultry operations and backyard flock owners susceptible to the virus. They have been conducting routine surveillance for avian influenza statewide since 2015.
Residents who suspect exposure to sick birds or wildlife are encouraged to contact the Disease Outbreak Control Division’s Disease Reporting Line for guidance. Overall, while the presence of HPAI in Hawaii is concerning, experts and authorities are taking proactive measures to prevent the spread of the virus and protect both animal and human populations.
