An Old Bird, A New Flu: America’s First H5N5 Human Case Ruffles Feathers

The Feathered Frontier: Bird Flu’s Newest Variant Goes Bipeds

In a move no one exactly had on their 2025 bingo card, an older resident of Grays Harbor County, Washington, has earned the dubious distinction of being America’s first human infected with the avian influenza strain H5N5. This marks not only a personal milestone (not a recommended bucket list item) but also the nation’s first human bird flu case since February. Progress?

Backyard Chickens: The Gateway to Epidemiological Adventure

Our patient, described only as an “older adult with underlying health conditions,” was tending a mixed flock of domestic poultry with a social calendar open to wild bird visitors. As it turns out, when you host backyard soirées for ducks and chickens, the guest list sometimes includes uninvited viral plus-ones.

Testing revealed the culprit: H5N5, a cousin to the better-known (and media-darling) H5N1. The two share genetic quirks, but H5N5 boasts a different “end piece”— virology’s version of a secret handshake, apparently enough to keep epidemiologists up at night, if only slightly.

Risk Assessment: Still a Bad Time to Panic

Authorities, in the measured tones of public health, assure us that the risk to the general public remains low. The Centers for Disease Control and Prevention and local health officials both agree: transmission between humans is about as common as a polite Twitter thread. No need to dust off the pandemic starter kits—yet.

Poultry Precautions and the Perils of Double Infection

Bird keepers, wildlife handlers, and anyone inclined to hug a goose are reminded to resist the urge. Protective gear, healthy boundaries, and swift reporting of sick animals are the order of the day. The usual flu vaccine, alas, is powerless against bird flu, but officials still recommend it—because a double infection could, in theory, spawn a super-flu more sociable than we’d like.

A Brief History of Avian Anxiety

Earlier this year, the nation’s bird flu emergency was officially dialed down, following a drop in animal cases and a human dry spell. But viruses, like reality TV, never truly disappear—they just bide their time for the next comeback. H5N5, until now, had stuck to birds. Its debut in a human host is a reminder that nature’s scriptwriters are always workshopping new plot twists.
