Bird Flu Bulletin: Daily H5N1 Update
Wednesday, December 31, 2025.
Good evening, this is your Daily H5N1 Update.
Top stories from the last 24 hours.
First, the CDC reports U.S. human cases remain steady at 71 since early 2024, with no new confirmations today, matching yesterday's total from their situation summary. Exposure sources include 41 from dairy herds and 24 from poultry operations.
Second, a new H5N1 outbreak hit a Wisconsin dairy herd, likely spread by wildlife, according to the American Veterinary Medical Association. This adds to 989 affected U.S. dairy herds across 17 states since March 2024, per USDA data.
Third, in the UK, NFU confirms HPAI H5N1 at a premises near Bridgewater, Somerset on December 29, with zones established, and a third case near Penicuik, Scottish Borders on December 24.
Case numbers show no change in U.S. humans versus yesterday per CDC. Globally, FAO notes 1738 H5 outbreaks in animals across 41 countries since October 23, 2025, with the U.S. reporting 415 new events in wild birds and mammals like polar bears and skunks.
Health authorities: CDC surveillance as of December 5 monitored over 21,300 people, testing 990 with no novel findings. WHO highlights 991 H5N1 human cases worldwide since 2003, 48% fatality.
Expert snippet: Dr. Marion Koopmans, virologist, states, "Wild bird surges in Europe quadrupled this fall per Science Alert, raising spillover risks, but human cases stay rare. Vigilance on dairy and poultry is key."
Looking ahead, expect USDA updates on wild bird detections through December 30, potential new European poultry culls from ongoing FAO reports, and CDC flu surveillance refresh early January. Monitor dairy herds amid wildlife spread.
