"Soaring Concerns: Resurgence of H5N1 Bird Flu Across the U.S. and Globally"

Bird flu is again making headlines in the U.S. this week after federal authorities identified a new case of H5N1 infection in a Texas dairy herd, the first reported in that state since May. The U.S. Department of Agriculture now counts 1,079 herds across 17 states that have been impacted since early 2024. According to the Center for Infectious Disease Research and Policy, this detection marks a continued threat, coming at a time when researchers still cannot pinpoint how a recent California child contracted the virus in an urban setting, despite genetic links to the dairy cow outbreak.

Meanwhile, the CDC has tracked a total of 70 confirmed human infections in the U.S. since the outbreak began in 2024, most cases resulting in mild symptoms such as eye and respiratory problems. No human-to-human transmission has been identified to date, and just one fatality has been reported in the U.S. by mid-2025, though experts highlight that undetected cases may exist due to limited testing. A recent study from the University of Maryland Institute for Health Computing emphasizes that, without broader surveillance, infected individuals with mild symptoms could go unnoticed, increasing the importance of quick action and real-time testing.

Poultry farms have also been hit: just this past week, turkey outbreaks were recorded at commercial farms in North and South Dakota, highlighting that the virus is still circulating in U.S. flocks. According to Food Business Middle East, the ongoing bird flu outbreaks have continued to disrupt the global poultry trade, prompting the UN's Food and Agriculture Organization to host a major meeting in Brazil this week.

Globally, Europe is facing a renewed surge with new bird flu outbreaks in Portugal and Germany, affecting wild birds, poultry, and even mammals like red foxes and otters. Human cases remain rare worldwide, with the European Centre for Disease Prevention and Control reporting 42 cases between December 2024 and June 2025, most tied to direct contact with infected animals. No sustained human-to-human spread has been observed, but the mutation and adaptability of the virus remains a concern for health officials.

As the outbreak’s impact continues to unfold, health experts and regulators urge ongoing vigilance—from testing and surveillance in both animals and humans to strict biosecurity on farms and prompt containment where outbreaks emerge. That’s your update on bird flu across the U.S. and the globe.
