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.

  • Alarming Bird Flu Resurgence Sparks Heightened Vigilance Nationwide

    Alarming Bird Flu Resurgence Sparks Heightened Vigilance Nationwide
    Nov 15 2025
    Bird flu headlines across the United States are drawing renewed concern after recent updates from public health officials. After a quieter summer period, Health Affairs Forefront reported yesterday that bird flu cases are once again ticking up nationally. While much of the focus has been on monitoring outbreaks among poultry, the attention shifted sharply this week following a significant human case.

    The Los Angeles Times reported that a resident in Washington state has been hospitalized after contracting a new form of bird flu, marking the first case of its kind in the country. The source of infection remains unknown, and officials are investigating whether there were any links to local poultry or exposure to infected birds. This case stands out because, until now, the US has not seen widespread transmission to humans, and the CDC confirms that no human-to-human spread of avian influenza A(H5) virus has been detected this week.

    Globally, bird flu continues to disrupt poultry industries and prompt border controls, especially in Europe and Asia, where outbreaks among flocks remain a persistent challenge. However, there have been no immediate reports of confirmed human infections internationally in the past 24 hours.

    The CDC, in its latest surveillance summary for the week ending November 8, confirms that there were no other confirmed human infections with the influenza A(H5) virus across the United States. Still, authorities remain on high alert as colder months typically see an uptick in both animal and human flu cases, and there is close scrutiny for any signs of human-to-human transmission.

    Experts urge Americans not to panic but remain informed. Health officials recommend avoiding contact with wild or sick birds, practicing good hygiene, and staying updated as government agencies continue rigorous monitoring of the situation.

    That wraps up this week’s coverage of bird flu developments in the US and abroad. Thanks for tuning in. Be sure to come back next week for more news updates. This has been a Quiet Please production, and for more, check out QuietPlease Dot A I.

  • Evolving Avian Flu Crisis: Outbreaks Surge Across the U.S. and Globe

    Evolving Avian Flu Crisis: Outbreaks Surge Across the U.S. and Globe
    Nov 13 2025
    Bird flu continues to make headlines in the United States and worldwide as new outbreaks and scientific discoveries raise concerns about the virus’s ability to spread and potentially adapt. In the last 24 hours, officials in Michigan confirmed highly pathogenic avian influenza in several additional poultry flocks, including three commercial farms in Ottawa County and backyard flocks in Monroe and St. Clair counties. According to the Michigan Department of Agriculture and Rural Development, these latest cases bring Ottawa County's flock total this year to 15. Agriculture authorities emphasize that strong biosecurity measures and personal protective equipment remain vital, and they encourage residents to report any unusual signs of illness or deaths in domestic or wild birds immediately.

    Nationally, the United States continues grappling with what experts describe as one of its worst bird flu outbreaks. Penn Vet reports that wild birds remain the main drivers of current spread, introducing H5N1 strains to domestic poultry and even mammals. The Conversation notes that since the arrival of HPAI A(H5Nx) in North America in 2021, more than 180 million birds and over 1,000 dairy cattle farms in the U.S. have been impacted. Mass die-offs in wild populations and persistent threats to domestic flocks have fueled concerns among scientists and farmers alike.

    States such as Washington are particularly hard-hit; Axios reports nearly 2 million cases in the region last month, making it the second-highest in the country. Outbreaks are also surging elsewhere including California, where SFGate says over 351,000 birds have been culled recently due to infection on Sonoma County farms. Globally, bird flu season started unusually early this year, with notable outbreaks not only in the U.S. but also in Japan and Europe according to Four Paws.

    Health experts are warning of a quiet, ongoing risk. Gavi’s VaccinesWork highlights findings of asymptomatic H5N1 infections in humans—meaning the virus could be spreading undetected and adapting for more efficient transmission. CDC experts and international virologists continue to monitor both H5N1 and emerging subtypes like H9N2, which recent research suggests may be developing greater pandemic potential.

    While the Centers for Disease Control and Prevention advises that public health risk remains low, scientists caution that ongoing genetic changes in the virus, combined with undetected transmission chains, could raise the threat level over time. Vaccine researchers, led by groups such as CEPI, are accelerating development of new flu vaccines and monitoring for further mutations.

  • Alarming Bird Flu Outbreak: Millions of Birds Impacted, Experts Warn of Pandemic Potential

    Alarming Bird Flu Outbreak: Millions of Birds Impacted, Experts Warn of Pandemic Potential
    Nov 12 2025
    The United States continues to grapple with an unprecedented and ongoing outbreak of bird flu, also known as H5N1 avian influenza. Over 180 million birds and more than 1,000 dairy cattle farms across the country have been directly impacted, according to the University of Nebraska Medical Center’s health security division. Wild birds are now recognized as the primary drivers of the current U.S. bird flu outbreak, with experts like Penn Vet’s Louise Moncla tracking H5N1’s persistent spread among native avian populations.

    Most concerning to scientists is the possibility that H5N1 may be spreading undetected among people. VaccinesWork reports that while bird flu has largely affected those in direct contact with sick animals, recent genetic changes in the virus have enabled it to infect mammals more efficiently. The Centers for Disease Control and Prevention have identified instances of asymptomatic human infection in multiple countries, raising the possibility that person-to-person transmission chains could be developing beneath the surface, untracked by standard monitoring systems.

    Rick Bright, of Bright Global Health, and Nicole Lurie of the Coalition for Epidemic Preparedness Innovations, emphasized in JAMA that these new patterns could signify an “emerging pandemic potential.” Lurie recently told VaccinesWork that, in the U.S., we’re at a point where cases may be spreading unnoticed. Human H5N1 infections have also now been reported in Mexico, Bangladesh, and Cambodia.

    The challenge is compounded by the rapid pace of viral evolution. The experience of COVID-19 underscores how easily a novel pathogen can escape early detection, granting more opportunities for mutation. With H5N1, the worry is that silent community spread—especially among those with mild or no symptoms—could give rise to a variant better adapted to human-to-human transmission. Public health officials also note the risk that co-infection with seasonal flu could accelerate these changes.

    This year’s avian influenza season has come earlier and harder than usual, according to animal welfare NGO FOUR PAWS. Outbreaks are expanding not just in the U.S. but also in Japan and Europe, signaling a global challenge likely to persist through the winter. Meanwhile, CEPI is investing millions into rapidly developing new H5N1 vaccine candidates using advanced biotech platforms to prepare should the situation escalate.

    New research also highlights the evolution of other bird flu strains, such as H9N2, which is showing greater potential to infect humans compared to previous years. Scientists worldwide are calling for intensified surveillance and public health preparedness.
