Bird flu appears to be rising in the U.S., but only among people exposed to infected animals — namely, cows and poultry.
Since April 2024, the U.S. has seen 36 human cases of H5N1 bird flu across 17 states. That includes 16 cases in California, seven of which were diagnosed in the week ending Oct. 20. That same week, six workers at a Washington egg farm were also diagnosed.
