Researchers have identified nine mutations in a bird flu strain from a person in Texas. Bad news: this strain is more capable of causing disease and replicates better in the brain. Good news: approved antivirals are still effective.

We isolated three genotypes of highly pathogenic avian influenza virus (HPAIV) clade 2.3.4.4b from wild birds infected with H5N1 (n = 12) and H5N8 (n = 1) in Hong Kong SAR 2021-2024. Viruses from two spoonbills from late 2022 were genetically related to a virus from a human in China. Four tested vir …

Clade 2.3.4.4b H5N1 high pathogenicity avian influenza virus (HPAIV) has caused a panzootic affecting all continents except Australia, expanding its host range to several mammalian species. In March 2024, H5N1 HPAIV was first detected in dairy cattle and goats in the United States. Over 891 dairy fa …

Trump's pick for health secretary has a record of attacking vaccines. In fact he's even taken direct aim at bird flu shots. Some scientists fear this doesn't bode well in case of a crisis.

During the peak Covid years, our public-health establishment vastly expanded its scope. Officials took it upon themselves to micromanage which aisles could stay open in stores and which playgrounds and

Dr Gilada, an infectious diseases expert, said that no one has the right to create psycho-terrorism with “hypothetical pandemic”.

Researchers at Texas Biomed identified nine mutations in a bird flu strain from a person in Texas. Bad news: this strain is more capable of causing disease and replicates better in the brain. Good news: approved antivirals are still effective.

The FX was a suitable format to test the PANDEM-2 solutions in 2 different country set-ups. It demonstrated the benefit of regular simulation exercises at member state level to test and practice public health emergency responses to be better prepared for real-life events.

Seasonal influenza vaccines triggered protective immune responses against the H5N1 avian influenza virus primarily in younger people, indicating its potential use as a first line of defense during an eventful pandemic.

Nature Reviews Biodiversity - The highly pathogenic avian influenza H5N1 is an emerging and unexpected threat to many wild animal species, which has implications for ecological processes, ecosystem...

Cases of avian influenza A (H5N1) continue to rise among cattle and humans in the USA. Scientists and government health officials are preparing for the potential of the virus adapting to enable human-to-human transmission.

CDC continues to assess that the current H5N1 bird flu risk to the general public remains low.

Evolutionary Adaptations in H5N1 Influenza: Implications for Human Health and Surveillance Strategies

Between 21 September and 6 December 2024, 657 highly pathogenic avian influenza (HPAI) A(H5N1) and A(H5N5) virus detections were reported in domestic (341) and wild (316) birds across 27 countries in Europe. Many HPAI outbreaks in domestic birds were clustered in areas with high poultry density and …

The introduction of HPAI H5N1 clade 2.3.4.4b viruses to North America in late 2021 resulted in avian influenza outbreaks in poultry, mortality events in many wild bird species, and spillovers into many mammalian species. Reassortment events with North American low-pathogenic virus were identified as …

We compared virus replication and host responses in human alveolar epithelium infected with highly pathogenic avian influenza (HPAI) A(H5N1) viruses. A/Vietnam/1203/2004 replicated most efficiently, followed by A/Texas/37/2024, then A/bovine/Ohio/B24OSU-342/2024. Induction of interferon-stimulated g …

Nature Communications - Here the authors show that a replicating RNA vaccine encoding the hemagglutinin (HA) of contemporary H5N1 strains confers single shot protection against lethal H5N1...

University of South Florida and Global Virus Network experts discuss H5N1.

China is allegedly seeing more human infections of the H5N1 bird flu, according to a source working in China’s disease monitoring and prevention sector. NTD has concealed the individual’s identity for security reasons. The source says there have been at least 100 H5N1 infections in the country to date. Authorities are said to be building […]

The variant circulating in America appears to be less lethal and could be triggering different responses from the immune system

Some animal welfare groups are calling on USDA to release data on whether cockfighting has contributed to the spread of bird flu in the U.S.

Scientists have identified nine new mutations in a bird flu strain from Texas that enable the virus to replicate more efficiently in the brain, but in a

The United States is taking proactive measures to combat the ongoing threat of avian influenza by creating a new vaccine stockpile.

The CDC has confirmed a positive bird flu case in a child in San Francisco, the second juvenile case of H5N1 in the country.

Study reveals that contemporary HPAI H5N1 viruses show reduced replication and immune activation in human lung organoids, potentially explaining milder disease in humans compared to historic strains.

Highly pathogenic avian influenza was reported at Kingoldrum, in the Kirriemuir area, on Friday.
