Avian Influenza News and Research

RSS

Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.

Overlooked animal viruses slipping past global disease surveillance

The study on Influenza D and Canine Coronavirus HuPn-2018 underscores urgent needs for targeted surveillance and diagnostics in infectious disease research.

Nasal spray vaccine prevents infection from highly pathogenic H5N1 virus

Researchers at WashU Medicine have developed a nasal vaccine against the highly pathogenic H5N1 avian influenza virus, or bird flu, which has jumped from wild birds to livestock to humans.

Mammary glands of domesticated livestock and humans could harbor avian influenza

An ongoing outbreak of highly pathogenic avian influenza has affected more than 184 million domestic poultry since 2022 and, since making the leap to dairy cattle in spring 2024, more than 1,000 milking cow herds.

Fever-resistant bird flu viruses pose a significant threat to humans

Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body's ways of stopping viruses in their tracks, according to new research led by the universities of Cambridge and Glasgow.

Gut immune cells follow an atypical pathway to provide long-lasting antiviral protection

A new study led by University of Toronto researchers has shown that immune cells in the gut follow an atypical pathway to produce antibodies that provide long-term protection against viruses.

Wild birds found to be key drivers of H5N1 outbreak in North America

Since late 2021, a panzootic, or "a pandemic in animals," of highly pathogenic bird flu variant H5N1 has devastated wild birds, agriculture, and mammals.

AI and protein language models can accelerate the design of antiviral antibodies

Artificial intelligence (AI) and "protein language" models can speed the design of monoclonal antibodies that prevent or reduce the severity of potentially life-threatening viral infections, according to a multi-institutional study led by researchers at Vanderbilt University Medical Center.

Machine learning model can accurately predict avian influenza outbreak patterns in Europe

Local factors such as seasonal temperature, the year-dependent water and vegetation index, and data on animal density can be used to predict regional outbreaks of avian flu in Europe.

WHO launches EIOS 2.0 to accelerate detection and response to public health threats

Today, the World Health Organization (WHO), in collaboration with key partners and supporters, launched version 2.0 of the Epidemic Intelligence from Open Sources (EIOS) system, used globally for the early detection of public health threats.

Bird flu virus survives in raw-milk cheese for months

Findings indicate H5N1 virus stability in raw-milk cheese for 120 days, emphasizing the need for revised safety measures in dairy products to protect health.

AI combined with the One Health approach can improve pandemic preparedness

Artificial intelligence could be a valuable tool for detecting emerging diseases earlier, researchers from five European universities and research institutes argue in The Lancet Infectious Diseases.

Generative AI model scans emergency notes to identify high-risk avian influenza exposures

Researchers from the University of Maryland School of Medicine developed a new and highly effective application of an artificial intelligence (AI) tool to quickly scan notes in electronic medical records and identify high-risk patients who may have been infected with H5N1 avian influenza or "bird flu", according to new findings published in the journal Clinical Infectious Diseases.

Early infection traits help predict future disease spread

When a disease-causing virus or other organism is transmitted from one species to another, most of the time the infection sputters and dies out.

21 Aug 2025

How shifting landscapes drive new bird flu threats across Asia

Landscape changes across the East Asian–Australasian Flyway have reshaped waterfowl migration, increasing interactions with poultry. This shift amplified cross-species viral transmission and raised the risk of avian influenza virus reassortment and diversification.

20 Aug 2025

Local climate and wildlife factors help predict avian flu outbreaks in Europe

Several local factors - including the minimum temperature reached in autumn, the water level in lakes and ponds in winter, and the presence of mute swans (Cygnus olor) - could be key for predicting the potential of an outbreak of highly pathogenic avian flu (HPAI) occurring in Europe.

17 Jul 2025

Letting bird flu run its course could spark wider pandemic

In a Policy Forum, Erin Sorrell and colleagues – a coalition of virologists, veterinarians, and health security experts – argue that the recent proposal to permit the uncontrolled spread of highly pathogenic avian influence (HPAI) among U.S. poultry to identify birds that survive infection is dangerous and unethical.

AI reveals how H5N1 virus is evolving to evade human immunity

The H5N1 avian influenza virus has infected birds and mammals around the world. As of June 2025, 70 people have been infected, and 1 person has died in the United States.

Scientists unlock potential of cytokine adjuvants in mRNA vaccines

In the quest to design vaccines that better help the body's immune system fight disease, scientists are always looking for more tools for their arsenal.

Researchers warn of bird flu survival in raw milk

The stability of H5N1 in unpasteurized milk poses potential health risks. Study findings emphasize the need for awareness among consumers and dairy workers.

Genomic analysis reveals how bird flu jumped from wild birds to poultry and people

Researchers identified a novel genotype (D1.1) of highly pathogenic avian influenza H5N1 spreading among wild birds, poultry, and a human in British Columbia, Canada, during fall 2024. Genomic analysis reveals the virus arose from reassortment between Eurasian and North American strains, with implications for surveillance and control.
