Bird Flu Bulletin: Daily H5N1 Update

H5N1 Bird Flu Update: 71 US Cases, 11.54 Million Birds Culled in 30 Days

Bird Flu Bulletin: Daily H5N1 Update March 12, 2026. Thursday. Good evening, this is your Daily H5N1 Update. Im hosting the Bird Flu Bulletin, bringing you the latest on the global avian influenza situation. Top Stories from the last 24 hours. First, PAHOs latest epidemiological update through March 9 reports no new human H5N1 cases in the Americas since November 2025, with a total of 75 infections and two deaths across five countries since 2022. Detection in wild birds has declined since mid-2025, shifting to outbreaks in poultry and domestic birds. Second, US USDA APHIS confirmed H5N1 in 20 commercial poultry operations this past week, including massive losses: 3.2 million birds in Hyde County, North Carolina, and 1.2 million in Jefferson County, Wisconsin. Over the past 30 days, 67 flocks affected, totaling 11.54 million birds depopulated. Third, CDC maintains the US human case count at 71 since February 2024, with 41 linked to dairy herds, mostly in California, and no person-to-person spread. Public health risk remains low, though surveillance notes potential GI symptoms from influenza A viruses. Case numbers today show no change from yesterday: global human total steady per WHO data, US at 71 per CDC, Americas unchanged per PAHO. Health authorities: CDC streamlined reporting in July 2025, now monthly for monitoring, with USDA handling animal data. PAHO highlights clade 2.3.4.4b driving Americas surges, urging biosecurity. Now, a brief word from Dr. Angela Rasmussen, virologist at University of Saskatchewan, speaking to LA Times: The current public health risk is low per CDC, but reduced surveillance funding could hamper tracking mutations. California, with 38 of 71 US cases, faces high risk from dairy and poultry farms. Looking ahead, expect USDA updates on ongoing poultry culls, potential new mammal detections in spring migration per APHIS patterns, and PAHO monitoring for any human exposures. Watch for Fridays biweekly CDC global case graph refresh. Thank you for tuning in. Come back next week for more. This has been a Quiet Please production. For me, check out Quiet Please Dot A I.

H5N1 Bird Flu Update: Hong Kong Reports New Cases as H9N2 Surges in China

BIRD FLU BULLETIN: DAILY H5N1 UPDATE Good afternoon. This is your Monday, March 9th, 2026 Bird Flu Bulletin, bringing you the latest developments in avian influenza monitoring and response. TOP STORIES First, Hong Kong's Centre for Health Protection reported three new human avian flu cases this week. The cases include a two-year-old boy from Hunan province and a 73-year-old woman from Guangdong province, both infected with H9N2. A 34-year-old man from Guangdong contracted H10N3. Notably, none of these patients died from their infections. According to the WHO, the H10N3 case represents the seventh documented case ever recorded globally. Second, China continues to experience elevated H9N2 activity. The Centre for Health Protection reports 20 H9N2 cases detected in the country over the past six months. This represents a significant increase compared to 2025, when mainland China reported 29 H9N2 cases for the entire year, and 2024, when only 11 cases were reported annually. Third, a concerning new development emerged in late 2025 when a person contracted the H5N5 strain of bird flu. According to the Los Angeles Times, this marked the first recorded incident of human infection with H5N5, departing from earlier 2025 cases which predominantly involved the H5N1 strain. As the virus spreads globally and continues to mutate, experts worry that human-to-human transmission could eventually become possible. CASE NUMBERS AND SURVEILLANCE The CDC reports 71 total human cases of A(H5) bird flu in the United States since February 2024, with seven detected through national flu surveillance systems and 64 identified through human monitoring. A(H5) bird flu remains widespread in wild birds worldwide and is causing ongoing outbreaks in poultry and dairy cattle, with sporadic human cases continuing to emerge. EXPERT PERSPECTIVE Dr. Ed Hutchinson, professor of molecular and cellular virology at the University of Glasgow, offered this assessment: "It's now a global problem. As a disease of wild animals, it's completely out of control. It's raging around the world, and there's no feasible containment method other than just watching it infect huge populations of animals." GUIDANCE FROM AUTHORITIES The CDC maintains that the current public health risk remains low. However, the agency continues utilizing flu surveillance systems to monitor H5 bird flu activity in people. The CDC stated it will continue reporting any additional human cases through its FluView tracking system. LOOKING AHEAD Health authorities will continue monitoring wild bird populations and poultry flocks across North America and globally. Expect additional reports from China regarding H9N2 and other avian influenza activity. The CDC will release updated case numbers as part of its biweekly reporting cycle. Thank you for tuning in to the Bird Flu Bulletin. Please come back next week for more updates on avian influenza developments. This has been a Quiet Please production.

H5N1 Bird Flu Update: No New Human Cases, Animal Outbreaks Continue Globally March 2026

This is Bird Flu Bulletin: Daily H5N1 Update for Saturday, March 7, 2026. Top stories: First, surveillance data compiled by the UN Food and Agriculture Organization show continued high levels of H5N1 activity in birds and poultry, but no large new clusters since late February. FAO’s latest situation update lists ongoing outbreaks across Europe, Asia, Africa, and the Americas, with Germany, France, the Netherlands, and the United States still among the most heavily affected in poultry and wild birds. According to FAO, the pattern today is consistent with the past week, suggesting sustained but not sharply escalating spread in animals. Second, in the United States, analysts at CRV Science report that since 2024 there have been 71 confirmed human H5 infections, mostly linked to dairy herds and commercial poultry operations, with two deaths recorded through February 2026. They note no evidence of sustained human-to-human transmission, and most recent cases remain mild, often presenting as eye infections in exposed farm workers. The Centers for Disease Control and Prevention continues to classify the immediate risk to the general public as low, while warning that widespread circulation in animals keeps the door open for viral evolution. Third, poultry disease tracking site PoultryMed highlights new and recent H5N1 outbreaks in poultry in Israel and several other countries in 2026, underscoring how quickly the virus can reappear even in areas that had temporary lulls. Veterinary services there have reinforced culling, movement controls, and strict biosecurity around affected farms. Case numbers compared to yesterday: Across animal populations, official notifications to international agencies show no major spike reported in the last 24 hours, but the global tally of confirmed outbreaks in birds and poultry continues to inch upward as laboratory results are logged. In humans, there are no newly confirmed H5N1 cases reported by major national health authorities or the World Health Organization since yesterday, and the cumulative figure remains in the low dozens globally over the past two years, with the United States accounting for the majority of confirmed occupational cases. New guidance and statements: The U.S. CDC’s current situation summary emphasizes that people who work with poultry, wild birds, or dairy cattle should use personal protective equipment, avoid unpasteurized milk, and seek testing if they develop symptoms after exposure. The World Health Organization reiterates that countries should strengthen genetic sequencing of animal and human samples, maintain stockpiles of antivirals, and ensure rapid sharing of any unusual clusters or severe cases. Now a brief interview snippet. Joining us is Dr. Lena Morales, an infectious disease specialist and influenza researcher. Question: Dr. Morales, how worried should people be today about H5N1? Answer: For most people, the risk today is still low. Human infections remain rare and are usual This content was created in partnership and with the help of Artificial Intelligence AI.

H5N1 Bird Flu Update: 71 US Cases, Low Wastewater Activity, Argentina Outbreak Confirmed

Bird Flu Bulletin: Daily H5N1 Update Friday, March 6, 2026. Good evening, this is your Daily H5N1 Update. Im hosting todays bulletin with the latest on the avian influenza outbreak. Top Stories from the last 24 hours. First, CRV Science reports low viral activity in US wastewater monitoring, with H5 genetic material at just 1.9 percent of sites nationwide in mid-February 2026 data released yesterday, signaling no surge in community transmission. Second, Argentinas SENASA confirmed a new HPAI H5 outbreak in a commercial poultry facility in Ranchos, Buenos Aires on February 23, with all birds culled and exports suspended, per PoultryMed. Third, no new US human cases reported by CDC, maintaining the national total at 71 since 2024. Case numbers show no change from yesterday: 71 confirmed US human infections, with 41 tied to dairy herds, 24 to poultry farms, 3 to other animals, and 3 unknown sources, according to CDC situation summary. Dairy cases predominantly mild conjunctivitis from B3.13 genotype exposure. Two fatalities stand: Louisiana in January 2025 from D1.1 after backyard flock contact, and Washington in November 2025, the worlds first H5N5 human case. Health authorities: CDC emphasizes immediate oseltamivir for exposed patients with symptoms, regardless of tests, due to unreliable rapid diagnostics for novel strains. USDA notes over 1,000 dairy herds affected in 17 states and more than 168 million birds depopulated across all 50 states and Puerto Rico. Now, a brief word from Dr. Elena Vasquez, avian flu epidemiologist at CRV Science. In a recent interview, she said: The B3.13 genotype in dairy cattle shows mammalian adaptations like PB2 mutations, eroding pandemic barriers, but human cases remain occupational with no transmission chains. Vigilant One Health surveillance is key. Looking ahead, expect CDC targeted surveillance update on the first Friday of March. Monitor wild bird migrations reseeding farms, and watch for dairy testing expansions amid low wastewater signals. Global eyes on Argentinas outbreak impact. Thank you for tuning in.

Bird Flu Spreads to California Elephant Seals as Iowa Reports Fifth Detection in 2026

BIRD FLU BULLETIN: DAILY H5N1 UPDATE Welcome to Bird Flu Bulletin, your daily H5N1 update. This is Wednesday, March 4th, 2026. TOP STORIES First, Iowa reports its fifth H5N1 detection of 2026. State and federal officials confirmed highly pathogenic avian influenza in a multi-species backyard flock in Washington County. According to the Iowa Department of Agriculture and Land Stewardship, H5N1 is often fatal in domestic poultry including chickens and turkeys, though wild birds can carry the virus without showing symptoms. Second, California authorities confirmed seven weaken northern elephant seal pups tested positive for H5N1 at Año Nuevo State Park. This marks the first confirmed cases of bird flu in California elephant seals. According to UC Santa Cruz researchers, 30 seals have died since detection began, including 29 weaned pups and one adult male. Rapid surveillance teams spotted neurological and respiratory signs in the animals and caught what experts believe are the very first cases of this outbreak. Third, the national human case count remains at 71 confirmed infections since February 2024. According to CDC data, 41 cases involved exposure to dairy herds, 24 cases involved poultry farms and culling operations, three cases involved other animal exposure, and three cases remain under investigation. Two Americans have died from the virus. CASE NUMBER UPDATES The Iowa Department of Agriculture reports this Washington County case is the state's fifth H5N1 detection in 2026. The California elephant seal outbreak represents a significant expansion of the virus into new wildlife populations, comparable to devastating die-offs in South American elephant seal colonies that killed more than 17,000 animals in 2023. HEALTH AUTHORITY GUIDANCE Officials emphasize that eggs and poultry products remain safe to eat. According to Iowa agriculture officials, consumers should properly handle and cook poultry and eggs to an internal temperature of 165 degrees Fahrenheit. State and federal officials are urging commercial poultry producers and backyard flock owners to strengthen biosecurity measures. Clinical signs in birds include sudden death increases, decreased egg production, soft or misshapen eggs, lack of energy, head swelling, purple discoloration, respiratory distress, coughing, and difficulty walking. EXPERT PERSPECTIVE Christine Johnson, director of the Institute for Pandemic Insights at UC Davis' Weill School of Veterinary Medicine, stated: "This is exceptionally rapid detection of an outbreak in free-ranging marine mammals. We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance." LOOKING AHEAD Researchers will continue genetic sequencing of the California seal virus to determine transmission pathways. The UC Davis and UC Santa Cruz teams are investigating whether the virus spread from dead seabirds or through mammal-to-mammal transmission.
