BIRD FLU BULLETIN: DAILY H5N1 UPDATE

Good evening. This is your Bird Flu Bulletin for Wednesday, January 21st, 2026. I'm bringing you the latest developments in avian influenza monitoring from around the world.

TOP STORIES

First, highly pathogenic avian influenza H5N1 continues spreading across Europe and North America. According to the UK government, England has now confirmed 72 H5N1 cases in poultry and captive birds during the 2025 to 2026 outbreak season, with Scotland reporting 7 cases, Wales 7 cases, and Northern Ireland 4 cases. The most recent confirmations came on January 19th when H5N1 was detected in commercial poultry near Bacton in Suffolk, triggering protective zones and mandatory culling of affected flocks.

Second, the Food and Agriculture Organization reports that 2,525 avian influenza outbreaks have been documented across 43 countries since late November 2025, with H5N1 accounting for 2,057 of these events. This represents a significant surge in animal infections globally.

Third, in the United States, the Centers for Disease Control and Prevention confirms 71 human H5N1 cases since 2024. Forty-one cases were linked to exposure to infected dairy herds, 24 to poultry farms and culling operations, with the remainder from other sources. The most recent human infection in the United States was reported on November 15th, 2025.

HUMAN CASE UPDATES

On the global human infection front, the Centre for Health Protection reports that since 2014, there have been 93 confirmed human cases of avian influenza A(H5N6), with 92 occurring in mainland China. No new H5N6 cases have been reported since July 24th, 2024. For H7N9, authorities have documented 1,568 total cases since March 2013, with zero new cases reported since October 2025.

EXPERT PERSPECTIVE

The persistent animal-to-human transmission risk remains a central concern for epidemiologists. While human-to-human transmission remains extremely rare, the sheer volume of infected animals increases the statistical probability of future human cases, particularly among individuals with direct occupational exposure to poultry or dairy operations.

LOOKING AHEAD

Health authorities expect continued surveillance of active outbreaks in the United Kingdom and United States over the coming days. Additional laboratory confirmations from wild bird sampling may emerge from Europe, where migratory patterns typically drive winter transmission. The dairy industry in the US will remain under heightened monitoring as H5N1 circulation in cattle herds continues.

For ongoing updates on infection status and protective measures, monitor the CDC, UK government health services, and the FAO's official situation updates.
