The United States has confirmed its first human death caused by the rare H5N5 strain of bird flu, prompting immediate action from health authorities. Experts emphasize, however, that the overall risk to the general public remains very low.
According to the Washington State Department of Health, the deceased was an elderly resident of Grays Harbor County with multiple pre-existing medical conditions. Health officials report that the individual’s weakened immune system and prior illnesses made the infection more severe, ultimately leading to fatal complications.
The individual had direct contact with domestic poultry, as a mixed flock of chickens and other birds was kept on the property, and two birds had died just days before the man became ill. Experts believe the virus likely spread from either infected domestic birds or wild birds that frequently enter the area.
Authorities confirm that none of the patient’s close contacts have shown symptoms of bird flu, and there is no evidence of further transmission.
The U.S. Centers for Disease Control and Prevention (CDC) reiterated that, despite this tragic death, the risk to the public remains extremely low. Surveillance efforts are being increased, and scientists are conducting genetic analyses of the virus to identify any significant mutations that could influence its spread.
It is important to note that the H5N1 strain of bird flu has been present in the U.S. among various animals and a small number of humans since 2022.
Between 2024 and 2025, the country recorded 71 human cases of H5 bird flu, most of which involved only mild symptoms, and none were fatal.
Health experts advise the public to avoid handling sick or dead birds. Individuals working with poultry are urged to use proper protective equipment and to seek medical attention immediately if they develop any symptoms of illness.
