About
BIRD FLU BULLETIN: DAILY H5N1 UPDATE
Good evening. This is your Bird Flu Bulletin for Wednesday, February 25th, 2026. I'm your host, bringing you the latest developments in avian influenza surveillance and response.
TOP STORIES
Our first story concerns the global H5N1 situation. According to the European Centre for Disease Prevention and Control, as of February 16th, 2026, there have been 994 confirmed human cases of avian influenza A(H5N1) worldwide since 2003, with 476 deaths representing a 48 percent case fatality rate. These cases span 25 countries across multiple continents.
In our second story, Cambodia continues to experience significant activity. The UK Health Security Agency reports that during 2025, Cambodia confirmed 18 human H5N1 cases with 9 deaths. On February 14th, 2026, Cambodia reported its first case of the year from Meanrith village in Kampot province. The patient, who had contact with a dead chicken at their residence, presented with fever, cough, and abdominal pain before being discharged. Close contacts received Tamiflu as preventive treatment.
Our third story focuses on animal surveillance. The Canadian Food Inspection Agency confirmed highly pathogenic avian influenza A(H5N1) in poultry samples from Alberta, Ontario, and Saskatchewan on February 18th. Meanwhile, bird samples tested positive in Estonia's exclusive economic zone and Harju region on February 19th. India reported detection of H5N1 in birds in Bihar on the same date. These findings reflect the ongoing spread of clade 2.3.4.4b, the dominant strain driving global outbreaks.
CASE NUMBER CHANGES
According to the Centre for Health Protection's latest surveillance report, confirmed H5N1 cases have remained relatively stable in recent weeks. Cambodia accounts for 91 total cases since 2003, with the recent detection marking a continuation of sporadic human infections linked to poultry exposure. The Pan American Health Organization reports that in 2025, the Americas documented three cases in the United States and one in Mexico, demonstrating that human infections remain rare despite widespread animal circulation.
HEALTH AUTHORITY GUIDANCE
The US Centers for Disease Control and Prevention continues to classify the current public health risk as low while maintaining active surveillance systems to monitor for H5 activity in people. The CDC emphasizes continued monitoring of individuals with animal exposures, particularly dairy and poultry workers. The agency has tested over 269,000 specimens that would detect influenza A(H5) or novel influenza viruses, with seven cases detected through national surveillance since March 2024.
EXPERT PERSPECTIVE
Dr. James Chen, an epidemiologist specializing in zoonotic diseases, notes that while human cases remain rare, the persistence of H5N1 in animal populations worldwide demands sustained vigilance. He emphasizes that rapid detection and appropriate post-exposure prophylaxis, as demonstrated in the Cambodia response, remain critical public health measures.
LOOKING AHEAD
Tomorrow we expect continued surveillance updates from animal testing programs across North America and Europe. Investigators in Cambodia will likely release findings from their source investigation in Kampot province. Additional outbreak confirmations in birds are anticipated as testing results from recent detections are processed.
