Based on the information available, this infection does not change CDC’s current H5N1 bird flu human health risk assessment for the U.S. general public, which the agency considers to be low.

The Centers for Disease Control (CDC) in an announcement that a third American has tested positive for the bird flu – the second known case to a recent outbreak connected to infected dairy cows.

Why It Matters: Bird flu in humans remains very rare with only three confirmed cases in the United States *in history*. The first case confirmed: a person working with infected poultry in 2022; the next two cases occurred this year in those working with cattle as the bird flu spread to dairy cows.

Notable: A symptom present in this recent case (consistent with the last confirmed case several weeks ago) = eye irritation or “pink eye” symptoms.

The extremely contagious nature of bird flu in birds, and the discovery of bird flu found in other animals like mountain lions, seals and now diary cows, has raised concerns about the ability of this flu virus to change, and more easily spread to and infect humans.
