NewsWild birds are driving the current U.S. bird flu outbreak
Researchers traced the introduction and spread of highly pathogenic H5N1 viruses during the first 18 months in North America using genomic sequencing and migratory flyway analysis, discovering that the viruses were spread primarily by wild migrating birds.
-
NewsEarly-stage clinical trial demonstrates promise of intranasal influenza vaccine in generating broad immunity
Researchers report encouraging results from an early phase clinical trial that found an experimental intranasal vaccine triggered a broad immune response against multiple strains of H5N1 ’bird flu’, highlighting the potential of mucosal immunization strategies.

NewsInactive H5N1 influenza virus in pasteurized milk poses minimal health risks
Proteins and genetic material from H5N1 influenza viruses have been found in pasteurized milk in the United States, but a study shows those inactive viral pieces represent little to no health risk. H5N1-contaminated milk that was pasteurized did not significantly affect the immune system.
-
NewsScientists trace the evolution of the H5N1 virus
Researchers have discovered that the currently circulating 2.3.4.4b clade of H5N1 has specific mutations in its genome that increase its human adaptive potential.
-
NewsImmunity to seasonal flu protects against severe illness from bird flu in ferrets
A study in ferrets — which have remarkably similar respiratory systems to humans — suggests that widespread immunity to H1N1 seasonal influenza virus may explain why exposure to H5N1 bird flu causes only mild symptoms in humans.
-
NewsGlobal virus network issues urgent call to action to mitigate the rising threat of H5N1 avian influenza
The Global Virus Network (GVN) has issued a call-to-action, calling on world governments to address the threat of H5N1 avian influenza by enhancing surveillance, implementing biosecurity measures, and preparing for potential human-to-human transmission.

NewsStudy: Experimental bird flu vaccine excels in animal models
A vaccine has demonstrated complete protection in mice against a deadly variant of the virus that causes bird flu. It focuses on the H5N1 variant known as 2.3.4.4b, which has caused widespread outbreaks in wild birds and poultry.
-
NewsScientists develop nasal spray H5N1 avian influenza vaccine
Scientists have pioneered an influenza virus vector-based nasal spray vaccine platform and developed a nasal spray H5N1 avian influenza vaccine.
-
NewsNew carrier birds brought avian flu to Europe, Americas
Unexpected wild species, from pelicans to peregrine falcons, are transporting the virus from poultry farms to new places around the world and changing where the risk of outbreaks is highest.
-
NewsNew biosensor can detect airborne bird flu in under 5 minutes
A new biosensor for monitoring aerosol particles of H5N1 works within five minutes, preserving the sample of the microbes for further analysis and providing a range of the pathogen concentration levels detected on a farm.

NewsKilling H5N1 in waste milk — an alternative to pasteurization
Researchers have found that acidification can kill H5N1 in waste milk, providing dairy farmers an affordable, easy-to-use alternative to pasteurization of waste milk.
-
NewsFrom Spanish flu to today: how immune cells keep up with a changing virus
In a breakthrough for influenza research, scientists have discovered immune cells that can recognise influenza (flu) viruses even as they mutate, raising hopes for a longer-lasting vaccine and a universal protection against future flu pandemics.
-
NewsAntibody treatment prevents severe bird flu in monkeys
A prophylactic antibody-based immune therapy protects monkeys against severe disease caused by H5N1 avian flu, a new study reports.
-
NewsBird flu is mutating - but antivirals still work
Researchers have identified nine mutations in a bird flu strain from a person in Texas. The bad news: this strain is more capable of causing disease and replicates better in the brain. Good news: approved antivirals are still effective.
-
NewsControlling infectious disease between wildlife and livestock on shared rangeland
New research looks at the nexus of wildlife and livestock for solutions to zoonotic disease. It examines the ongoing threat of emerging pathogens that can necessitate prompt deployment of medical countermeasures for life-saving interventions.
-
NewsGlobal research team develops advanced H5N1 detection kit to tackle avian flu
Researchers have developed an advanced diagnostic kit for detecting the highly pathogenic H5N1 Avian Influenza Virus (AIV). This development marks a significant breakthrough in avian influenza monitoring, reinforcing global efforts in pandemic preparedness.
-
NewsNew roles in infectious process for molecule that inhibits flu
Researchers have identified new roles for a protein long known to protect against severe flu infection – among them, raising the minimum number of viral particles needed to cause sickness.
-
NewsWashington coast avian flu outbreak devastated Caspian terns, jumped to seals
An epidemiological study found that 56% of a large breeding colony of Caspian terns died from a 2023 outbreak of highly pathogenic avian influenza at Rat Island in Washington state. Since then, no birds have successfully bred on the island.
-
News‘Food theft’ among seabirds could be transmission point for deadly avian flu
The deadly H5N1 avian influenza virus, which has killed millions of birds worldwide since 2021 – and in rare cases can be transmitted to humans – may be spread through the food-stealing behaviour of some seabirds.

NewsAvian flu found in wastewater of 10 Texas cities through virome sequencing
Avian influenza A(H5N1) virus, which spread to cattle and infected 14 people this year, has been detected using virome sequencing in the wastewater of 10 Texas cities.
