Ongoing H5N1 Outbreaks in US Livestock and Wildlife: Experts Warn of Potential Spread to Humans

H5N1 bird flu continues to circulate widely in the United States, with GISAID reporting ongoing spread in dairy cows, poultry, and wild birds as of January 23, 2026, based on the latest genetic trees updated just days ago. The clade 2.3.4.4b strain has triggered 71 confirmed human cases since April 2024 per CDC genome analysis, mostly mild eye and respiratory symptoms in farm workers exposed to infected animals, though one case showed a rare mammalian adaptation marker. In the US, the FAO notes 1,409 H5N1 outbreaks in animals since October 2025, hitting poultry, dairy, and wildlife like bald eagles and red foxes, with the latest on January 16. CDC's weekly flu report for the week ending January 17 confirms no new H5 human infections, maintaining zero person-to-person spread, amid elevated seasonal flu but declining hospitalizations at 2.9 per 100,000. Globally, FAO tallies 1,391 HPAI outbreaks in 39 countries since December 23, 2025, including fresh H5N1 events in Europe like Belgium and Germany, and H5N9 in South Korea as recent as January 21. Three child H9N2 cases surfaced in China in January per WHO, all recovered after backyard poultry exposure. Notably, H5N1 hit a Dutch dairy cow, the first outside the US, signaling potential wider cattle risks. Raw milk remains a concern, with high virus loads detected and a new review in Pediatrics on January 22 exploring it as a transmission vehicle. No major US human escalations in the last day, but vigilance continues amid animal surges. Thank you for tuning in. Come back next week for more.
