Bird Flu Update: US H5N1 News Now

[Host upbeat, professional tone, news broadcast style]

Welcome to Bird Flu Update: US H5N1 News Now. Im your host, bringing you the latest on the ongoing avian influenza situation in the United States. Today, were covering confirmed cases in humans and animals, updates from CDC and USDA, guidance changes, key research, what it means for you, and how things stack up against recent weeks. All facts straight from official sources like CDC and USDA reports.

First, human cases. CDC confirms 71 total H5N1 cases in the US since 2024, with 41 linked to dairy herds, 24 to poultry operations, three to other animals, and three unknown. The most recent in 2025, as of late February per CDCs February 26 spotlight, include a dairy worker in Nevada, a poultry worker in Ohio, and a backyard flock owner in Wyoming. No person-to-person spread detected, and public risk remains low. Louisianas case marked the first US H5N1 human death.

In animals, its widespread. USDA data shows 989 dairy herds affected in 17 states since March 2024, plus 336 commercial poultry flocks and 207 backyard flocks totaling over 90 million birds. California reports ongoing dairy outbreaks, with CDFA confirming cases in up to 28 herds in recent 30-day periods through late February 2025. Wild birds see rising mortalities this winter, per Cornell Ag Informer and New York ag alerts, especially waterfowl like snow geese and Canada geese in states including Pennsylvania, Ohio, and New York. Recent die-offs: 70 black vultures in Ohio and 400 snow geese in Pennsylvania in December.

CDC and USDA updates from the past week: No major shifts since CDCs July 2025 streamlined reporting, now monthly with FluView. USDA handles animal data. Public health risk low, but surveillance ramps up for exposed workers.

Guidance steady: CDC monitors via flu systems, testing over 240,000 specimens since 2024, detecting seven cases. Biosecurity key, per Cornell and state ag departments: Lock barns, limit wild bird contact, report sick animals. Dairy and poultry workers, pasteurize milk, cook eggs and meat fully.

Research note: CDCs analysis of recent cases found PB2 mutations like D701N and E627K, linked to better mammal replication but no antiviral resistance or vaccine issues. New University of Michigan work uses AI and robotics to test bird flu drugs, published February 2.

For you: Risk is low unless handling sick animals. Avoid wild bird droppings, practice hygiene. Milk and eggs safe when pasteurized or cooked.

Compared to prior weeks: Stable human cases, no surge beyond three in early 2025. Animal detections persist at high levels into this fourth outbreak year, with winter wild bird upticks expected through spring migration, per Farm and Dairy.

Bird Flu Update: US H5N1 News Now

[Host, energetic journalistic tone, like NPR news]

Welcome to Bird Flu Update: US H5N1 News Now. Im Perplexity, bringing you the latest on the ongoing H5N1 outbreak as it enters its fourth year in the United States. Today, well cover recent cases in humans and animals, CDC and USDA updates, guidance changes, key research, what it means for you, and how things stack up against prior weeks.

First, human cases. According to the CDC, there have been 71 confirmed H5N1 cases in humans since 2024, with 41 linked to dairy herds, 24 to poultry farms, and the rest from other animal exposures or unknown sources. Two deaths: one in Louisiana from backyard poultry exposure, and the 71st case, a fatal H5N1 infection in an older Washington state resident with underlying conditions who had contact with infected backyard poultry in November 2025, per Los Angeles Times reporting. No person-to-person spread detected, and public health risk remains low, says the CDC.

In animals, the USDA reports H5N1 widespread in wild birds, with 16,657 detections since 2022, including recent ones like 70 black vultures in Ohio and 400 snow geese in Pennsylvania in December. Poultry losses are massive: 187 million birds culled since 2022. A January 28 case hit a 1.5 million-hen flock in Lancaster County, Pennsylvania. Dairy cattle: 1,084 cases across 19 states since March 2024, though none in the past 30 days in spots like California, Texas, and Wisconsin. Farm Progress America notes over 1.1 million birds affected recently after a December slowdown, with 17 commercial and 42 backyard flocks hit in the past month.

Past week updates: CDC streamlined reporting on July 7, 2025, now monthly via FluView, dropping routine USDA animal data from their site. USDA launched free biosecurity webinars and a federal order for mandatory testing of lactating dairy cattle before interstate movement plus reporting positives. Support for affected dairy farms includes up to 120 days of aid for virus elimination.

Guidance changes emphasize enhanced PPE for dairy and poultry workers due to raw milk risks, though pasteurization kills the virus safely. Biosecurity is key: limit visitors, use barriers.

Research highlights: West Virginia University got a $2 million grant for an edible poultry vaccine. Washington University Medicine showed a nasal vaccine protects rodents against H5N1 variants. GISAID notes ongoing clade 2.3.4.4b spread, with trees updated January 23, 2026, including new genotypes in cows and humans.

For listeners: Risk to general public is lowavoid sick birds or raw milk. Farm workers: wear PPE. Poultry owners: boost biosecurity. No bird feeder takedowns needed unless you have domestic flocks.

Compared to previous weeks: After Decembers dip, cases surgedJan saw wild bird detections up in migration, per West Virginia officials, and that big PA flock. Human cases flat since February until Novembers fatality.

[Upbeat news intro music fades in and out]

Good evening, this is Bird Flu Update: US H5N1 News Now. I'm your host, bringing you the latest on highly pathogenic avian influenza across the United States.

Starting with confirmed cases: The CDC reports 71 human H5N1 cases since 2024, with 41 linked to dairy herds, 24 to poultry operations, and two deaths, mostly among farm workers. No new human cases in the past week per CDC's FluView for week ending January 17, 2026. In animals, the outbreak enters its fourth year, with USDA data showing 187 million birds affected since 2022 across all states. Recent detections include a January 28 case in 1.5 million egg-laying hens in Lancaster County, Pennsylvania; dead ducks from HPAI in Winter Springs, Florida's Torcaso Park this week; five positive cases in snow geese and ducks in Suffolk County, New York in January; and suspected bird flu in 70 black vultures in Ohio and 400 snow geese in Pennsylvania in December. Dairy cattle cases total 1,084 in 19 states, with California confirming new H5N1 detections as of January 30, 2025, leaving four herds under quarantine, including one re-quarantined site.

From federal agencies: CDC streamlined H5 updates on July 7, 2025, now reporting human cases monthly via FluView, with over 22,000 people monitored through December 27, 2025, and 1,010 tested post-exposure. USDA tracks animal outbreaks, noting persistent wild bird detections during fall migration. No new guidance changes this week, but California maintains a ban on poultry and dairy exhibitions due to ongoing infections.

On research: West Virginia University received a $2 million grant for an edible poultry vaccine, addressing nasal vaccine challenges for large flocks. Washington University reports a nasal vaccine protected rodents against H5N1 variants.

For listeners: Risk to the public remains low, as pasteurization kills the virus in milk, and human infections require close animal contact. Avoid sick or dead birds, report wildlife deaths via FWC apps in Florida or similar tools, and farm workers should use PPE. No need to remove backyard bird feeders unless you have poultry.

Compared to prior weeks: Human cases stable at 71 with no uptick; animal detections continue steadily, but California's quarantines dropped from 13 in October 2025 to four now, versus higher peaks like 35 herds in prior 30-day periods. Wild bird cases persist into winter, unlike seasonal spring-fall surges.

Good evening. I'm bringing you the latest on bird flu in the United States. This is Bird Flu Update: US H5N1 News Now.

The H5N1 bird flu situation continues to evolve across America. According to the CDC, there have been 71 confirmed and probable human cases of H5N1 since 2024. Of these, 41 cases were linked to exposure on dairy farms, 24 to poultry farms and culling operations, three to other animal exposure, and three cases have unknown exposure sources. Tragically, Louisiana reported the first H5 bird flu death in the United States.

Recent developments show the outbreak remains active. The California Department of Food and Agriculture confirmed H5N1 in 28 dairy farms within the last 30 days as of late January. Meanwhile, the Rhode Island Department of Health reports that since March 2024, H5N1 has been identified in dairy farms across several states, with more than 50 human cases documented in the US since April 2024. Most people who contracted H5N1 experienced mild illness, received antiviral treatment, and recovered.

The CDC's genetic analysis reveals evolving viral patterns. On March 19, 2025, the CDC released specimen data from the first human case in Ohio, which belonged to genotype D1.3. Previous cases from farm workers in Iowa and Wisconsin showed genotype D1.1, the same strain detected in poultry and wild birds affecting cases in Washington state and a severe case in British Columbia.

Regarding food safety, the FDA has reassured the public about dairy products. According to FDA testing conducted between June and July 2024, all 167 retail dairy product samples tested negative for viable H5N1 virus, including aged raw milk cheese, pasteurized fluid milk, and products like cream cheese, butter, and ice cream. The FDA confirms that pasteurization effectively inactivates the H5N1 virus. The agency began sampling 60-day aged raw milk cheese in December 2024, with 110 samples collected by March 2025. Of those, 96 tested negative by PCR, with results expected to continue through spring 2025.

Comparing current conditions to previous weeks, the situation shows both persistence and caution. As of early January, the CDC reported 17,579 laboratory-confirmed influenza-associated hospitalizations from October 2025 through January 10, 2026, though most were standard seasonal influenza, not H5N1. The weekly hospitalization rate stood at 5.6 per 100,000 population, decreasing from 11.6 the previous week. The cumulative rate was 50.4 per 100,000 population, the second highest since the 2010-2011 season.

For listeners, here's what you need to know. If you work with poultry or dairy cattle, follow proper safety protocols and report any signs of illness in animals immediately. The general public should know that properly pasteurized dairy products remain safe. If you develop respiratory symptoms and have had animal exposure, consult a healthcare provider and mention your exposure history.

The CDC and USDA continue investigating this outbreak with coo

Bird Flu Update: US H5N1 News Now

[Upbeat news theme fades in]

Host: Welcome to Bird Flu Update: US H5N1 News Now, your three-minute briefing on the latest developments. Im CDC data from the week ending January 10, 2026, shows H5N1 remains widespread in wild birds, poultry, and dairy cows, with sporadic human infections. No new human cases were confirmed in the past week, but since 2024, the US has reported 74 human cases and two deaths, mostly mild among exposed workers, per recent HPJ reports.

In animals, USDA APHIS detections in wild birds continue nationwide as of January 13, with ongoing outbreaks in dairy herds across states like Kansas and Minnesota leading new confirmations this month, according to HPJ. CDC's situation summary confirms H5N1 circulation in US regions, including recent genotype D1.3 in an Ohio human case from March 2025 and D1.1 in dairy cows since February 2025, as shared via GISAID.

From the past week, CDC's FluView for Week 1 reports no specific H5N1 updates but notes declining influenza hospitalization rates nationally at 8.1 per 100,000, down from 11.6 last week, possibly due to holiday reporting dips. USDA and FDA emphasize steady containment, with FDA's ongoing raw milk cheese sampling showing 96 of 110 tests negative for H5N1 as of March 2025, reinforcing pasteurization's effectiveness.

No changes to official CDC or USDA guidance this week: avoid raw milk, sick birds, or contaminated surfaces; report ill livestock. Practical tips for you: If you handle birds or dairy cattle, wear PPE and monitor for flu-like symptoms. The commercial milk supply stays safe thanks to pasteurization, per FDA outreach. Public risk remains low without sustained human transmission.

Compared to previous weeks, human cases are stable with no uptick, unlike seasonal flu's recent peak hospitalization rate of 12.6 per 100,000 in Week 52. Animal detections persist but without escalated outbreaks, per USDA wild bird data. Scientists via Science Focus warn of pandemic potential if adaptation occurs, but current trends show control.

Stay vigilant, wash hands, and cook poultry thoroughly. This has been Bird Flu Update: US H5N1 News Now, a Quiet Please production. Thank you for tuning income back next week for more. For me, check out Quiet Please Dot AI.

[Host upbeat, professional news tone, with subtle background music fading in]

Welcome to Bird Flu Update: US H5N1 News Now, your three-minute briefing on the latest developments. Im Perplexity, bringing you the facts from CDC, USDA, and frontline reports as of this week.

First, human cases: CDC reports 71 confirmed H5N1 infections in the US since 2024, mostly mild. The majority stem from dairy herds with 41 cases, poultry farms and culling at 24, other animal exposure at 3, and 3 unknown. Louisiana noted the first US H5N1 human death, but no new cases this week. All patients recovered with antivirals.

In animals, outbreaks rage on. USDA confirms H5N1 in dairy cows across states like California, where CDFA reported 2 new dairy herd cases in the last 30 days, plus 200 dairies released from quarantine. Poultry hits hard too: STAT News analysis shows 25 states with cases last month, worst January on record for 2025, surpassing 2024 and 2023. Eggs took 75% losses, turkeys 11%, chickens 8%. Recent APHIS data: 70 flocks confirmed in past 40 days, including 17 commercial in Delaware and Georgia. Wild birds remain widespread per USDA APHIS, last updated January 13.

CDC and USDA updates this week: No major guidance changes, but FDA affirms pasteurization kills H5N1 in milk, with ongoing silo studies and retail tests showing no viable virus in 167 samples. Research highlights include FDAs thermal inactivation studies with Cornell and genome-edited chickens at Wisconsin-Madison to boost resistance.

For you at home: Risk to public stays lowno human-to-human spread. Cook poultry and eggs thoroughly, avoid raw milk, wear PPE if around sick animals. Vaccinate against seasonal flu to ease burden.

Compared to prior weeks: Human cases flat at 71, but animal outbreaks surged25 states active versus fewer last month. Hospitalizations for seasonal flu dropped to 5.6 per 100,000 this week from 11.6, all influenza A dominant, no H5N1 spike.
