Bird Flu Update: US H5N1 News Now
# Bird Flu Update: US H5N1 News Now Good evening. This is your bird flu update for March 2026. We're tracking significant developments in the ongoing H5N1 outbreak affecting the United States. As of early March, the CDC confirms 71 total human cases of avian influenza A(H5) reported since February 2024. Two deaths have been documented. The first fatality occurred in Louisiana in January 2025, involving a person over 65 with underlying health conditions who contracted the D1.1 genotype after exposure to backyard flocks and wild birds. The second death happened in Washington State in November 2025, caused by an H5N5 virus in a similarly vulnerable patient with chronic medical conditions. The majority of human cases remain mild. Among the 71 cases, 41 are linked to exposure in dairy cattle herds, predominantly affecting farm workers. These cases typically present with acute conjunctivitis and mild upper respiratory symptoms, primarily associated with the B3.13 genotype. Twenty-four cases came from commercial poultry farms and culling operations, while three cases involved other animal exposures. Three additional cases have unknown exposure sources, raising concern among public health officials about possible unrecognized environmental reservoirs. Current animal surveillance shows widespread viral activity. Recent reports indicate bird flu has been confirmed at 67 poultry flocks in the past month, including 36 commercial operations and 31 backyard flocks. Environmental monitoring in mid-February detected H5 genetic material at only 1.9 percent of nationwide surveillance sites, suggesting viral activity remains relatively contained. The CDC and state health departments continue monitoring over 31,900 people exposed to infected birds, poultry, dairy cows, and other animals for ten days following exposure. More than 1,300 individuals have undergone testing for novel influenza A. This represents a significant public health surveillance effort across the country. For animal agriculture, the situation remains challenging. Dairy herds in multiple states continue showing infections, with California reporting numerous affected farms throughout 2025. The USDA emphasizes that while the virus has caused severe economic damage to commercial poultry and widespread illness in dairy cattle, the immediate physiological risk to the general human population remains relatively low. Comparing conditions to previous weeks, viral activity has actually decreased. The dramatic surge in poultry cases during September, October, and November 2025 has given way to lower detection rates heading into spring. Experts predict we may see increased spread during wild bird migration seasons in spring and fall, but current trends suggest a quieter period. What does this mean for you? If you work in agriculture or handle birds or livestock, maintain strict hygiene protocols and report any unusual illness in animals to authorities immediately. For the general public, the risk of h This content was created in partnership and with the help of Artificial Intelligence AI.
