A Washington State resident has died from H5N5 bird flu. This case marks the world’s first death from this rare strain and the first recorded human infection. Officials say the event highlights a new chapter in global bird flu surveillance.
The patient was older and had underlying health conditions. They had been hospitalized for an extended period before death, and state officials provided no further identifying details. Investigators are still reviewing the patient’s medical and exposure history.
The CDC confirmed the H5N5 infection and continues to classify the public risk as low. Officials say that no additional people have tested positive for bird flu. They also report no evidence of human-to-human transmission at this time.
Investigators say the patient was exposed by a backyard flock with mixed domestic bird species. Exposure to infected birds remains the most common source of transmission. Officials are monitoring nearby flocks to ensure no further spread occurs.
What Bird Flu Trends Relate to This Death?
The United States has now recorded two bird flu deaths in the last year. The previous death involved H5N1 in a Louisiana resident. More than 70 human bird flu cases have been confirmed nationwide since last year.
The WHO has documented over 1,000 global bird flu cases since 2023 across 25 countries. This figure includes all circulating bird flu strains now affecting humans. Officials say continued outbreaks highlight long-term risks that require close monitoring.
Officials say samples pinpointed Berkeley virus in the patient’s backyard flock. This discovery confirms that he was most likely exposed there. Others also had contact with the flock, so officials are monitoring them.
Bird flu is caused by influenza type A viruses. These viruses circulate naturally in wild aquatic birds worldwide. Bird flu can spill into other bird species and sometimes mammals. Outbreaks can kill large numbers of domestic birds like chickens and turkeys.
How to Stay Safe from Bird Flu
Human infections are rare, but some cases can be fatal. The Washington Department of Health shared several guidelines to prevent infection. They say these steps can reduce risk for people with backyard birds.
People with backyard poultry should avoid sick or dead birds. Report any poultry illness to proper authorities quickly. Vets must also report any sick or dead domestic animals that might have bird flu. People should avoid touching sick or dead wildlife, especially wild birds.
Keep pets away from dead birds and other sick wildlife. Avoid raw or undercooked foods, including raw cheese and unpasteurized milk. These items should also be kept away from pets.
People exposed to domestic or wild birds should receive a seasonal flu vaccine. This vaccine does not block bird flu infection directly. It instead prevents someone from being sick with both viruses simultaneously. Dual infection could allow a bird flu virus to evolve person-to-person spread.
Health officials recommend seasonal flu vaccines for everyone six months or older. They say widespread vaccination reduces overall flu risk. It also helps protect communities during large bird flu outbreaks.
Conclusion
Health officials say this death highlights rising concerns about evolving bird flu strains. They stress that human risk remains low but requires continued monitoring. Officials also urge people to follow safety guidance to reduce future infections.
