With the number of cases continuing to grow, leaders from the National Institutes of Health are calling for more action to tackle the bird flu outbreak.

State and federal agricultural officials identified a sixth case from 2024 of highly pathogenic avian influenza in Nebraska in late December.

An outbreak of H5N1 bird flu in Nigeria has spread to 21 commercial farms in seven different states, with more than 140,000 birds having been exposed to the virus, the agriculture minister said on Thursday.

Covid-19 is responsible for the deaths of millions of people around the world, but researchers fear the next global outbreak could be even worse, making it vital that we start preparing for that unknown pathogen now

Examples of recent discussions

Health workers close to the case of a 13-year-old critically ill with bird flu published details about the case in a cautionary letter.

By learning lessons from other sectors, public health can ensure it is ready to face future outbreaks in record time.

In 2024, several human infections with highly pathogenic clade 2.3.4.4b bovine influenza H5N1 viruses in the United States raised concerns about their capability for bovine-to-human or even human-to-human transmission. In this study, analysis of the ...

Why the results surprised anyone is itself a surprise. After the state of California began testing dairy herds for highly pathogenic avian influenza, known also as bird flu or H5N1, in August, it found the pathogen on 645 dairy farms.

COPIAH COUNTY, Miss. (WJTV) – Officials with the Mississippi Board of Animal Health (MBAH) announced that poultry from a commercial broiler chicken flock in Copiah County has tested positive …

Why my threat assessment has changed.

A novel #H5N1 bird flu strain impacts animals and raises human health concerns. Enhanced biosecurity and research are key to managing risks and preventing outbreaks.

As the bird flu outbreak nears its fourth year, a new strain sparks concerns of potential human transmission, prompting increased biosecurity measures.

Apart from #H5N1 influenza A virus or bird flu, which has set the alarm bells ringing in the US, malaria tuberculosis, and HIV are the three infectious diseases causing the biggest concern for health officials around the world

Identifying broadly reactive B precursor cells and conserved epitopes is crucial for developing a universal flu vaccine. In this study, using influenz…

The coronavirus brought us to our knees, but H5N1 could knock us flat.

A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a recent study published in the Journal of Virology, a journal of the American Society for Microbiology. The work highlights that the interface between animals and humans that may give rise ...

Balancing enhanced vigilance and “business as usual.”

Most human cases of bird flu in North America have been mild, a fact that’s underscored by a new study of the first 46 confirmed human H5N1 infections in the United States this year. But the case of an ill Canadian teen stands out because of its severity and because the source of exposure remains a mystery.

Highly pathogenic avian influenza H5N1 was confirmed in commercial poultry on 31 December 2024.

Genetic analysis of H5N1 bird flu virus that infected a Canadian teenager shows 'worrisome' mutations, new studies reveal.

I remain stunned at how poorly we are responding to the threat from H5N1. Our poor response to COVID was regrettable but perhaps understandable given the US hadn’t faced a major pandemic in decades. Having been through COVID, however, you would think that we would be primed. But no. Instead of acting aggressively to stop […]

Highly pathogenic avian influenza (HPAI) A(H5N1) emerged in 1997.1 Since then, it has spread globally by migratory birds, resulting in infections in animals on every continent. HPAI A(H5N1) clade 2...

Highly pathogenic avian influenza A(H5N1) viruses have caused widespread infections in dairy cows and poultry in the United States, with sporadic human cases. We describe characteristics of human A...

Influenza A(H5N1) viruses are an emerging zoonotic threat and have spread widely throughout birds in North America. Recently, influenza A(H5N1) infection led to serious illness in a teenager in Canada.
