Avian influenza or bird flu refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses naturally spread among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. Bird flu viruses do not normally infect humans. However, sporadic human infections with bird flu viruses have occurred.

  • Devastating Bird Flu Ravages US Agriculture: Over 185 Million Birds Lost Since 2022

    Devastating Bird Flu Ravages US Agriculture: Over 185 Million Birds Lost Since 2022
    Jan 15 2026
    Bird flu continues to devastate American agriculture as the H5N1 outbreak shows no signs of slowing. According to STAT News analysis of Department of Agriculture data, the United States has gained almost no ground since the outbreak began in 2022, with 2025 proving worse than 2024, which was worse than 2023. January 2025 was the worst month on record.

    Since 2022, the outbreak has resulted in the loss of nearly 185 million birds raised for food. The egg industry has borne the brunt, representing 75 percent of lost animals, while turkeys account for about 11 percent and meat chickens 8 percent. Most animals have not died from the flu itself but have been killed preemptively as part of federal policy when housed near infected flocks.

    The current situation remains dire heading into winter. Farm Progress reports that bird flu has spread across 11 states since the end of December, with 25 states experiencing cases in the last month. The CDC notes that while the current public health risk to Americans remains low, H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and dairy cattle, with sporadic human cases appearing among dairy and poultry workers. To date, person-to-person transmission has not been identified in the United States.

    The economic toll on consumers has been staggering. In one year of the outbreak, consumers spent 14.5 billion dollars more on eggs due to supply reduction. Taxpayers have also borne significant costs, with the USDA spending 1.8 billion dollars on response in the first three years, mostly through indemnification payments to farmers.

    Agriculture experts and lawmakers have urged the government to pursue vaccination as a solution. According to STAT News reporting, the USDA has licensed at least eight vaccines and has poured money into bird flu vaccine development for years. France reduced its outbreak size by up to 99 percent when it vaccinated ducks. However, the official USDA policy remains limited to biosecurity measures and mass killing, with Agriculture Secretary Brooke Rollins stating that vaccines are off the table, citing concerns about trade barriers with international partners.

    Multiple bipartisan congressional members, including Senate Majority Leader John Thune, have publicly urged the administration to pursue a targeted vaccination strategy. Major farming trade groups agree on the need for vaccination. The USDA has announced a draft national vaccination strategy, though its future remains unclear.

  • Alarming Bird Flu Outbreak: H5N1 Virus Spreads Unchecked, Threatening Global Health Crisis

    Alarming Bird Flu Outbreak: H5N1 Virus Spreads Unchecked, Threatening Global Health Crisis
    Jan 13 2026
    # Bird Flu Update: Global Threat Intensifies as H5N1 Spreads Unchecked

    Scientists are sounding the alarm about bird flu as the H5N1 virus continues its relentless spread across the globe. According to the World Health Organization, there have been 992 human infections with avian influenza since 2003, with nearly 48 percent proving fatal. The situation has grown increasingly dire since the virus was first detected in 2020.

    Dr. Ed Hutchinson, a professor of molecular and cellular virology at the University of Glasgow, told BBC Science Focus that the virus is now "completely out of control" as a disease of wild animals. He explained there is no feasible containment method other than watching it infect huge populations of animals as it rages around the world.

    The scale of the outbreak is staggering. Over 285 million birds have been affected in the United States alone since February 2022. More alarming is the virus's ability to jump species barriers. In 2024, H5N1 was discovered in dairy cattle for the first time, an development no one anticipated. The CDC reports that 71 cases of human transmission from poultry or cattle have occurred in the U.S., resulting in two deaths.

    What makes this particularly concerning is the virus's genetic makeup. Researchers from Cambridge and Glasgow universities discovered that bird flu viruses are resistant to fever, meaning that human body temperature increases during illness may not provide protection. This is due to a specific viral gene that allows the virus to thrive at higher temperatures similar to birds' body temperatures.

    Globally, the current strain, known as clade 2.3.4.4b, evolved between 2018 and 2020 and has spread worldwide by 2021 through 2023. Scientists warn the virus is just one mutation away from sustained human-to-human transmission, which could spark a pandemic.

    In December, the National Veterinary Services Laboratories confirmed a new spillover event of H5N1 into dairy cattle, genotype D1.1, indicating the virus continues to evolve and jump between species. The Global Virus Network urged countries in April 2025 to improve surveillance and implement biosecurity measures to prepare for potential human-to-human transmission.

    While the CDC currently assesses the public health risk to Americans as low, the agency is monitoring the situation carefully. Scientists will continue watching throughout 2026 for evidence that H5N1 has mutated enough to transmit from person to person, a development that could trigger a global health emergency.

  • Headline: Experts Warn Raging Bird Flu Outbreak Poses Escalating Animal Health Crisis, But Remains Low Risk to Humans

    Headline: Experts Warn Raging Bird Flu Outbreak Poses Escalating Animal Health Crisis, But Remains Low Risk to Humans
    Jan 10 2026
    U.S. health officials say bird flu remains a serious animal health crisis but not yet a human one, even as scientists warn the virus is “completely out of control” in wildlife and livestock globally, according to reporting compiled by the University of Nebraska Medical Center and Science Focus.

    The Centers for Disease Control and Prevention’s latest FluView update for the week ending January 3, 2026, reports no human H5 bird flu infections detected through its national influenza surveillance systems and continues to rate current public health risk in the U.S. as low, even as seasonal flu activity stays elevated. The CDC notes that H5 bird flu has not been identified in routine respiratory samples from patients hospitalized with influenza-like illness, underscoring that human cases remain rare and sporadic.

    Experts remain uneasy. Scientists interviewed by Science Focus and summarized by UNMC’s Global Center for Health Security this week say highly pathogenic H5N1 has now infected hundreds of millions of birds, swept through poultry operations, and become established in U.S. dairy cattle since 2024, a species jump few anticipated. They describe the virus as “raging around the world” in wild animals, with no realistic way to eliminate it from nature, raising the long-term risk of further mutations.

    Globally, infectious-disease specialists writing in The Conversation and carried by Gavi’s VaccinesWork platform say H5N1 will be one of the most closely watched viruses in 2026. Researchers are looking for any genetic changes that might enable efficient human‑to‑human transmission, the key step toward a pandemic. Current seasonal flu vaccines are not expected to protect well against H5N1, but several targeted bird flu vaccine candidates are under development and could be deployed for high‑risk workers if needed.

    For now, officials emphasize that people at greatest risk are those with prolonged, unprotected exposure to infected birds, cattle, or their environments, such as farm and processing‑plant workers. Consumers are advised to avoid raw milk and ensure poultry, eggs, and meat are thoroughly cooked, standard food safety measures that inactivate influenza viruses.
