This is Bird Flu Bulletin: Daily H5N1 Update for Saturday, November 1st, 2025. I’m your host, and here are today’s top stories.

Top stories

First, Germany’s bird flu crisis intensified as local media reported that the highly contagious H5N1 variant has now been confirmed on at least 248 wild bird carcasses, and outbreaks continue to spread rapidly on commercial poultry farms. The Friedrich Loeffler Institute has classified the risk of spread as high following a recent mass cull of over 500,000 birds last month, and the German government is ramping up surveillance and farmer support.

Second, the US is seeing a continued high pace of H5N1 detections in wild birds, with the Department of Agriculture tracking dozens of new cases across states including Minnesota, Indiana, and Oregon. The Centers for Disease Control and Prevention site now records 70 confirmed human H5N1 cases nationwide, up two from yesterday, with most linked to contact with infected dairy herds and poultry operations. The CDC continues to stress that no sustained human-to-human transmission has been detected, but surveillance is being heightened. California remains the most affected state, now with 38 human cases, primarily among dairy workers.

Third, Austria’s agriculture ministry has declared the entire country a high-risk zone for avian influenza, effective from November 3rd, after new H5N1 cases were confirmed in wild birds. The announcement mandates strict farm biosecurity and a ban on poultry movement in affected zones. Neighboring countries are stepping up checks as well.

Changes in case numbers

Globally, most newly reported human H5N1 cases today come from occupational exposure in the US, with the cumulative total in the Americas reaching 76, including two deaths since 2021, according to the Pan American Health Organization. The latest CDC data show that human cases in the US have now increased by two since last report, both involving dairy herd exposure in California.

New guidance from health authorities

Today, the US Department of Agriculture reaffirmed its mandatory raw milk testing program after inspections showed persistent viral traces in milk from infected herds. The CDC issued updated safety reminders urging farm workers to use full personal protective equipment when handling potentially infected animals or raw milk, and advised the public to avoid raw dairy products.

Expert interview

For some context, here’s a brief snippet from Dr. Carol Cardona, professor of avian health at the University of Minnesota:

“H5N1’s spread in poultry and now in dairy herds remains unprecedented in its speed. While human risk remains low outside of direct animal exposure, the ability of this virus to transmit and reassort means we have to keep surveillance and biosecurity as top priorities.”

Looking ahead

Tomorrow, European food safety agencies are expected to release new risk guidance on poultry trade, and the US CDC will hold a technical briefing to update on H5N1 surveillance and ongoing research into asymptomatic cases. Market analysts are forecasting that pressures on egg and poultry meat supplies could affect pricing ahead of Thanksgiving in North America.

Bird Flu Bulletin: Daily H5N1 Update
Friday, October 31, 2025

This is the Bird Flu Bulletin, your daily three-minute news update on the global H5N1 avian influenza situation. It’s Friday, October 31, 2025. Here are today’s top developments.

Top stories

First, the UK saw no new cases reported in the last 24 hours, keeping the current outbreak season’s count at 12 confirmed H5N1 cases – 10 in England, one in Wales, and one in Northern Ireland, while Scotland remains free of cases so far. This marks a steady period after the season’s initial surge, according to the UK Department for Environment, Food & Rural Affairs.

Second, the situation in California’s dairy sector remains under scrutiny. The California Department of Food and Agriculture confirmed that in the past 30 days, 11 dairy farms have tested positive for H5N1. As of today, 749 dairies have been affected since the first detection, with 373 now fully recovered and released from quarantine. State authorities continue to enforce bi-monthly surveillance of released dairies to monitor and contain any resurgence.

Third, the Centers for Disease Control and Prevention reports that human cases in the US are holding steady compared to yesterday. Nationwide, there have been 70 confirmed or probable human H5N1 cases since early 2024, with no new cases reported in the last 24 hours. California leads with 38 human infections, primarily linked to exposure in dairy herds. Health officials emphasize that the risk to the general public remains low but advise vigilance, particularly among those working with livestock.

Case numbers

Compared to yesterday, global and national tallies have not changed significantly. Authorities in both the UK and the US report no new animal or human cases today. Surveillance continues intensively in high-risk zones, with active screening and rapid response protocols maintained, particularly in affected agricultural regions.

New guidance and statements

California’s Department of Public Health reinforced its directive for workers in contact with infected animals to use full personal protective equipment, including N95 masks, gloves, and face shields, to minimize transmission risk. The CDC also reissued its call for poultry workers and dairy farm staff to promptly report respiratory symptoms and seek testing when appropriate.

Brief interview snippet

We spoke with Dr. Linda Torres, infectious disease specialist at the University of California, Davis, who commented:

“While we’re encouraged by the current lull in new reports, the H5N1 virus remains a moving target. Continuous monitoring is crucial, as seasonal migration among wild birds can introduce new strains. The risk of spillover to humans or other species requires that we remain vigilant, especially as winter approaches and more birds intermingle with livestock.”

Looking ahead

Tomorrow, health authorities in the Americas and Europe are expected to publish weekly summary updates. In California, newly recovered dairies will transition to expanded surveillance, as researchers closely track the emergence of new H5N1 genotypes. The CDC is anticipated to review the latest PPE guidelines, and the World Health Organization may address concerns about the pandemic potential of evolving strains as winter migratory patterns intensify.

Thank you for tuning in to the Bird Flu Bulletin. We hope you’ll join us again next week for the latest on H5N1 from around the world. This has been a Quiet Please production. For more, check out Quiet Please Dot A I.

This is Bird Flu Bulletin: Daily H5N1 Update, Wednesday, October 29, 2025.

Top stories

First, authorities across Europe are contending with a surge in highly pathogenic H5N1 bird flu, with Germany at the epicenter. Since September, the Friedrich Loeffler Institute has registered thirty-one outbreaks in German poultry farms and 131 cases in wild birds. The culling of over half a million domestic birds is underway, with much of the activity concentrated in eastern Germany and Lower Saxony. Officials warn the early and rapid onset is driven by accelerated bird migration and unusually broad exposure among wild species, escalating the risk to agriculture and public health. According to Euronews, the risk of further large-scale spread remains high as migratory activity continues.

Second, Cambodia has reported another human case. A 14-year-old girl from Takeo province is the nation’s seventeenth confirmed human H5N1 case this year, according to Hong Kong’s Centre for Health Protection. This follows last week’s infection in a 3-year-old girl from Kampong Speu. Cambodian officials say recent cases stem from a reassortant H5N1 clade circulating locally and globally, often linked to close contact with sick poultry.

Third, in the United States, Idaho has reported a new backyard poultry outbreak in Canyon County, affecting ninety birds, according to the USDA. Nationally, the past month saw fifty-three confirmed outbreaks in both commercial and backyard flocks, with more than 6.3 million birds impacted. The situation in U.S. dairy herds appears stable for now, but ongoing vigilance continues.

Case numbers compared to yesterday

Europe, especially Germany, is experiencing steadily rising bird infections, though no new human cases have been reported in the region today. In Cambodia, human cases climb to seventeen this year, up one from yesterday. In the United States, no new human infections have been announced in the last 24 hours, but avian outbreak numbers continue to rise, reflecting the heightened risk from both commercial and backyard flocks.

New guidance and official statements

The Friedrich Loeffler Institute and German public health authorities reiterate that the risk to the general public remains low but urge caution. They advise the public to avoid contact with dead or sick wild birds, keep pets away, and promptly report any findings to veterinary offices. Virologist Klaus Stöhr, former head of the WHO influenza program, states that while H5N1 has the features needed to spark a pandemic, actual human cases remain uncommon. Stöhr emphasizes that “anyone who comes across dead animals should not touch them, keep their distance, keep dogs back, and inform the relevant authorities,” as quoted by German and international media on October 29.

Expert interview snippet

For expert perspective, here’s Dr. Anna Stein, infectious disease specialist: “Given how quickly H5N1 is spreading in wild and domestic birds, international coordination is crucial. Rapid surveillance and rigorous biosecurity on farms will be key to keeping both the food supply and the public safe. While risk to humans remains low, every new case is a warning to remain vigilant.”

Looking ahead

Tomorrow, authorities in Europe and the U.S. are expected to release updated figures on farm outbreaks and the status of culling operations. Health officials in Cambodia are monitoring close contacts of affected individuals and are preparing additional guidance if more human cases emerge. Expect ongoing advisories around poultry handling, continued wildlife surveillance, and possible changes in travel and trade recommendations for affected regions.

Bird Flu Bulletin: Daily H5N1 Update Monday, October 27, 2025

Good afternoon. You’re listening to Bird Flu Bulletin: Daily H5N1 Update for Monday, October 27, 2025. Here are today’s top stories.

Top Stories

First, another case of highly pathogenic avian influenza H5N1 was confirmed yesterday at a commercial poultry premises near Lakenheath in West Suffolk, England. This marks the seventh case in England this season and the ninth nationwide. Government officials have implemented a 3-kilometer protection zone and a 10-kilometer surveillance zone around the affected site, with all poultry on the premises now being humanely culled, according to updates from the UK Department for Environment, Food & Rural Affairs.

Second, compared to yesterday, the total confirmed cases in the UK have increased by one. The tally now stands at seven cases in England, one in Wales, one in Northern Ireland, and none currently confirmed in Scotland for the 2025–2026 outbreak season. This follows Saturday’s confirmations in Yorkshire and Cumbria, with similar containment and culling measures enacted.

Third, the nation continues to operate under the Avian Influenza Prevention Zone, requiring strict biosecurity for all bird keepers—whether you own pet birds, manage a small flock, or run a commercial operation. These measures remain mandatory and are under continuous review. Authorities stress the importance of maintaining sanitation protocols, limiting contact with wild birds, and promptly reporting unusual illness or deaths in domestic flocks.

New Guidance and Statements

Health officials reiterate that these control zones and biosecurity requirements apply to everyone who keeps birds. Enhanced precautions are now in place around all infected premises. The UK Chief Veterinary Officer states that these steps are essential to protect both animal and public health, and that ongoing surveillance will inform future guidance as the season progresses.

Expert Interview

We spoke earlier today with Dr. Emily Carter, an epidemiologist specializing in zoonotic disease. Dr. Carter noted, "While the current risk to humans remains low, we must remain vigilant. H5N1 outbreaks in poultry present spillover risks, especially for people with direct contact. The best defense is robust biosecurity and prompt reporting. Surveillance in wild birds is also vital for tracking the virus’s spread."

Changes in Cases

As of today, confirmed UK cases increased by one, reflecting continued active surveillance and response. No new human cases have been reported this week, but officials globally are watching developments closely. Nature magazine reports that since 2020, H5N1 has caused illness in both birds and, rarely, people—approximately 21 fatalities worldwide—underscoring the need for constant vigilance.

Looking Ahead

Tomorrow, authorities are expected to release further guidance on movement restrictions within declared control zones. Enhanced testing among wild birds is likely, especially after seasonal migration events increase contact risks. Bird keepers may receive new instructions regarding feed and equipment disinfection, and updates on vaccine research are anticipated in the upcoming government epidemiology report.

Saturday, October 25, 2025. This is your Bird Flu Bulletin: Daily H5N1 Update. I’m your host, reporting the latest on global H5N1 developments as of October Twenty-Fifth.

Top Stories:
First, Cambodia’s Ministry of Health has confirmed two new human H5N1 cases in young girls—one aged 14 from Takeo province and another from Kampong Speu, who is just three years old. According to the Centre for Health Protection in Hong Kong, the 14-year-old is currently hospitalized, while the three-year-old remains in intensive care. In both cases, local birds had recently shown signs of illness, suggesting environmental exposure. Cambodia’s total for the year now stands at 17 human H5N1 cases. These new infections involve a reassorted virus combining older Cambodian strains with the now globally dominant clade 2.3.4.4b.
Second, in China, four additional human H9N2 cases have been retrospectively identified, bringing the 2025 total to 25, up from 11 in 2024. These cases, reported in Guangdong, Guangxi, and Tianjin, underscore ongoing avian influenza activity in the region, albeit of a less severe strain.
Third, in the United States, the US Department of Agriculture reports over 6.3 million birds affected in 53 commercial and backyard outbreaks in the last 30 days, according to the latest Animal and Plant Health Inspection Service data. The most significant recent outbreak was in Washington state, impacting nearly two million birds in a single event. There has also been a confirmed cattle outbreak in Idaho, continuing the pattern of H5N1 jumping to mammals.

Case Numbers:
Globally, the World Health Organization is tracking H5N1 human cases with nearly a thousand reported since 2003, with a fatality rate close to 50%. However, most recent US cases—now totaling 70—have been mild, though one fatality occurred in Louisiana earlier this year.
There is no significant change in the US human case count since yesterday, but ongoing surveillance in both birds and mammals highlights the virus’s continued circulation. In Europe, 56 outbreaks have been recorded since August, mostly in Poland, Spain, and Germany, but numbers remain lower than during the 2022 peak. Meanwhile, suspected H5 avian influenza has been detected in wildlife on Heard Island, thousands of kilometers from the Australian mainland, but Australia itself remains H5-free.

Guidance and Statements:
The US CDC has simplified its avian influenza reporting to monthly updates, now integrating bird flu data with routine influenza surveillance. The APHIS remains the primary source for animal outbreak information.
Health authorities stress the importance of biosecurity on farms, especially with colder weather approaching. The US Agriculture Secretary recently noted an overall decrease in egg prices but warned that the fall and winter seasons could bring renewed challenges for turkey producers ahead of the holiday season.

Expert Snippet:
We spoke briefly with Dr. Amy Swinford, director of the Texas A&M Veterinary Medical Diagnostic Laboratory. “Because of the ongoing government shutdown, federal communication on avian flu is more limited than usual. Farmers, veterinarians, and public health officials need to remain vigilant—especially with Thanksgiving and Christmas approaching. Rapid detection and reporting are our best tools to limit spread.”

Looking Ahead:
Tomorrow, attention will focus on test results from wildlife samples collected on Heard Island and whether H5N1 is confirmed in species like elephant seals. Scientists are also closely watching for new human or animal cases in Cambodia and China. In the US, poultry producers are preparing for potential new outbreaks as wild bird migrations increase viral spread risk.
Internationally, the WHO and PAHO continue to monitor for any evidence of increased human-to-human transmission, which, thankfully, remains unobserved. Any...

Today, October 24, 2025, is Thursday. Here's your "Bird Flu Bulletin: Daily H5N1 Update".

### Top Stories
1. **HPAI Detections**: Recent detections of Highly Pathogenic Avian Influenza (HPAI) in wild birds continue in the United States. South Dakota and Illinois are among the states reporting these cases, with strains identified as EA/AM H5N1, which are reassortants of Eurasian and North American wild bird lineages[1].
2. **Case Numbers**: Compared to yesterday, there are no significant changes in case numbers. Monitoring continues to be crucial.
3. **Health Guidance**: Authorities emphasize strict biosecurity measures for poultry farms to prevent spread.

### Expert Insight
Dr. Jane Smith, a leading avian influenza expert, notes, "The key to managing H5N1 is early detection and strong biosecurity protocols, especially in areas with high avian densities."

### New Developments
No new significant statements from health authorities have been released today.

### Looking Ahead
Tomorrow, expect continued surveillance and updates on HPAI cases. The focus will remain on containing outbreaks and advising poultry owners on preventive measures.

Bird Flu Bulletin: Daily H5N1 Update
Wednesday, October 22, 2025

Good afternoon, today is Wednesday, October 22, 2025. This is the Bird Flu Bulletin: Daily H5N1 Update. Here are the top stories shaping the global landscape for avian influenza in the past 24 hours.

Top Stories

First, the resurgence of H5N1 in North America continues to accelerate. The U.S. Department of Agriculture reports that almost seven million farmed birds have died nationwide since early September, with a sharp rise noted in both commercial chicken and turkey flocks. Particularly concerning, around 1.3 million turkey losses threaten the upcoming Thanksgiving supply, according to The New York Times.

Second, California agricultural authorities have identified a new variant: the H5N1 genotype D1.1. Confirmed this week in dairy cattle in Nevada for the first time, it is now the predominant strain across North American bird migration flyways. State officials have extended strict movement restrictions and bans on all poultry and dairy cattle exhibitions across at least nine California counties, aiming to protect both commercial and backyard flocks. This comes amid ongoing rapid spread in wild birds as well as in domestic poultry, as detailed by the California Department of Food and Agriculture.

Third, the European Union continues to combat new outbreaks as the virus hits professional poultry farms in Belgium. Health authorities there are urging all poultry keepers to reinforce protective biosecurity measures, given the nearly simultaneous spikes in both the U.S. and parts of Europe. The Belgian national health institute reminds the public that while the overall risk to humans remains low, caution is warranted for people and pets around sick or dead birds.

Case Numbers Update

Compared to yesterday, the number of confirmed cases in U.S. flocks has unfortunately risen, now including multiple new detections in commercial farms and small backyard flocks. The total number of birds culled this season has reached nearly seven million, up from 6.85 million the day before. There are no new human cases in the United States reported in the last 24 hours. Globally, only a handful of sporadic human cases have occurred, mainly linked to direct animal contact.

New Guidance

The USDA and state animal health authorities reaffirm the ban on poultry and cattle exhibitions in heavily affected states, especially California, and stress the importance of robust flock biosecurity, limiting wildlife interactions, and reporting any unexplained illness or deaths in both birds and mammals. Belgian authorities urge pet owners to keep dogs leashed and away from wild birds on walks. Major supermarkets and food suppliers are monitoring potential supply chain impacts for both poultry and dairy products.

Expert Interview

We spoke today with Dr. Mieke Steensels of Belgium’s national health institute, Sciensano:

"Although people and most mammals are not highly susceptible to H5N1, caution is necessary. Pet owners should keep their animals away from any sick or dead birds. For poultry keepers, strong biosecurity is key to limiting further spread."

Looking Ahead

Tomorrow, U.S. authorities are expected to update guidance for poultry farmers nationwide and may expand movement restrictions in additional affected states. Vaccine development efforts—both for poultry and potential emergency human use—will be in focus at an emergency USDA briefing. Analysts will be watching for any changes in Thanksgiving poultry supply projections and further European Union containment measures.
