Expert insights from University of Delaware faculty on: Understanding waterfowl movement and bird flu

Paul Klotman and Anthony Maresso, both of Baylor College of Medicine, say the U.S. needs to act now to prevent an H5N1 pandemic.

In this NEJM Outbreaks Update, Editor-in-Chief Eric Rubin and Deputy Editor Lindsey Baden are joined by state public health leaders Robbie Goldstein and Jennifer Shuford to discuss action against H...

A new H5N1 bird flu mutation has appeared in a cluster of infected dairy cows. It's a genetic change that scientists say could not only make the virus more lethal, but increase its spread between mammals and possibly humans.

Novel galectin antagonist blocks H5N1 virus entry, potentially eliminating need for mass culling. Bioxytran's breakthrough could revolutionize poultry disease management.

What is Bird Flu?  How bad is it? Who is most vulnerable?  What’s the solution? What’s going on right now?  As of March 7, 2025, confirmed bird flu cases in humans (by state) are as follows:  State: CA WA CO NV WY OR TX LA MO IA WI MI OH Cases: 38 11 10 1 […]

While the ongoing H5N1 outbreak has affected the United States, it is good to know what the avian flu is and how the virus can hit cats.

Life science companies developing bird flu vaccines are gaining attention as the avian influenza subtype H5N1 becomes an increasing concern. The United States is in the midst of an H5N1 bird flu outbreak that began in February 2024 and is now threatening the nation’s poultry and cattle industries. W...

Nature Medicine - H5N1 strain-specific antibodies are higher in older individuals and correlate more with birth year than with age, suggesting that younger individuals are potentially more likely...

Scientists are sounding the alarm about a concerning genetic mutation of the H5N1 bird flu virus, recently identified in four dairy cow herds, as this

H5N1 mutation in US dairy herds prompts caution on pandemic potential - Sacramento, March 13 Scientists are sounding the alarm about a concerning genetic mutation of the H5N1 bird flu ... Get Latest News on Health only on lokmattimes.com

Scientific Reports - Superior replication, pathogenicity, and immune evasion of a Texas dairy cattle H5N1 virus compared to a historical avian isolate

As of early March, 30 poultry operations in Canada were dealing with avian influenza outbreaks: 16 in B.C., 10 in Ontario, and one each in Alberta, Quebec, Nova Scotia and Newfoundland and Labrador.

Pandemic influenza remains a significant global health threat, as signalled by the circulation and cross-species transmission of avian influenza A(H5N1) viruses from the clade 2.3.4.4b, including among dairy cattle in the USA since 2024. Although most of the reported human infections from the USA so far1,2 have been mild, the virus can change its profile rapidly. To reduce mortality and morbidity from influenza in humans, vaccines remain the most important intervention.

By Gary Ford, policy advisor, BFREPA February has been a challenging month for the poultry sector with the ongoing threat and indeed cases of Avian flu in [...]

Older adults who were exposed to seasonal flu viruses that circulated prior to 1968 are more likely to have some protection against H5N1, and that children would benefit more from H5N1 vaccines.

As bird flu continues to circulate among animals in the U.S. with some human cases, about six in 10 (58%) people overall have at least “a fair amount” of trust in the Centers for Disease Control and Prevention (CDC) to provide reliable information about bird flu, though only 21% have a “great deal of trust,”…More

We measured stability of infectious influenza A(H5N1) virus in irradiated raw milk and wastewater and on surfaces. We found a relatively slow decay in milk, indicating that contaminated milk and fomites pose transmission risks. Although the risk is low, our results call for caution in milk handling …

H5N1 viruses belonging to clade 2.3.4.4b have caused unprecedented outbreaks globally. Outbreaks of H5N1 virus were reported in poultry and wild birds from Kerala (India) in the year 2024. Samples from birds and the environment were collected. Real-time RT-PCR and virus isolation using embryonated c …

Our results indicate a high frequency of spillover events to red foxes at a time when there was a peak of H5N1 infections in wild birds in Bavaria. Phylogenetic analyses show no specifically close genetic relationship between viruses detected in mammalian predators within a geographic area. While di …

The first highly pathogenic H5N1 emerged in 1959 on a chicken farm in Scotland. The ancestor of the strains presently circulating was isolated in 1996 from a domestic goose in China. Since 1997, more than 900 severe human infections have been reported. However, in nearly thirty years, H5N1 has faile …

The rapid and sensitive detection of H5N1, a highly pathogenic avian influenza virus, is crucial for controlling its spread and minimizing its impact on public health. In this study, we developed a novel biosensor based on strand displacement amplification (SDA) coupled with CRISPR/Cas12a for highly …

By: Najla Alexander Westfield officials announced that their Regional Health Department (WRHD) is urging pet owners to be vigilant following reports of bird flu (H5N1) in cats.The virus has recently been detected in several outdoor cats in Hunterdon County and over 100 domestic cats nationwide, Westfield officials stated.

Since March 2024, highly pathogenic avian influenza A(H5N1) viruses have caused outbreaks in dairy cattle and poultry in the United States, and they continue to spill over into humans. However, data on human immune response to those viruses is limited. We report neutralizing antibody responses in 2 …

Analysis of H5N1 2.3.4.4b sublineage origins and K193 and N193 prevalence in human isolates

Highly pathogenic avian influenza H5 viruses have spread globally, established sustained transmission in mammals and caused human infections. Research on these viruses is restricted to high biocontainment laboratories. We report the characterization and utility of a surrogate, replicating virus that …

During 2023-2024, highly pathogenic avian influenza A(H5N1) viruses from clade 2.3.2.1c caused human infections in Cambodia and from clade 2.3.4.4b caused human infections in the Americas. We assessed the susceptibility of those viruses to approved and investigational antiviral drugs. Except for 2 v …
