Emerging Novel Reassortant Influenza A(H5N6) Viruses in Poultry and Humans, China, 2021

Emerging Infectious Diseases, 2022
A novel highly pathogenic avian influenza A(H5N6) clade 2.3.4.4b virus was isolated from a poultry market in China that a person with a confirmed case had visited. Most genes of the avian and human H5N6 isolates were closely related. The virus also exhibited distinct antigenicity to the Re-11 vaccine strain.

Genetic Characterization of Highly Pathogenic Avian Influenza A(H5N6) Virus, Guangdong, China [PDF]

Emerging Infectious Diseases, 2015
To the Editor: Since the first detection of the influenza A(H5N1) virus in geese in China during 1996 (http://www.cdc.gov/flu/avianflu/h5n1-virus.htm), H5 subtype viruses have continued to reassort and evolve, giving rise to multiple virus clades and gene constellations. Recently, clade 2.3.4.4 viruses have shown a predilection for genetic reassortment,

Avian influenza overview September–November 2025

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.

Assessing potential pathogenicity of novel highly pathogenic avian influenza (H5N6) viruses isolated from Mongolian wild duck feces using a mouse model

Emerging Microbes and Infections, 2022
Several novel highly pathogenic avian influenza (HPAIVs) A(H5N6) viruses were reported in Mongolia in 2020, some of which included host-specific markers associated with mammalian infection. However, their pathogenicity has not yet been investigated. Here,

Characterization of Highly Pathogenic Avian Influenza Virus A(H5N6), Japan, November 2016 [PDF]

Emerging Infectious Diseases, 2017
Highly pathogenic avian influenza viruses (HPAIVs) A(H5N6) were concurrently introduced into several distant regions of Japan in November 2016. These viruses were classified into the genetic clade 2.3.4.4c and were genetically closely related to H5N6 HPAIVs recently isolated in South Korea and China.

Clinical and Immunological Characteristics of Human Infections With H5N6 Avian Influenza Virus

Clinical Infectious Diseases, 2018
H5N6 avian influenza virus (AIV) has caused sporadic, recurring outbreaks in China and Southeast Asia since 2013, with 19 human infections and 13 deaths. Seventeen of these infections occurred since December 2015, indicating a recent rise in the frequency of H5N6 cases.To assess the relative threat of H5N6 virus to humans, we summarized and compared ...

A Systematic Review of New, Enhanced Surveillance Systems and Methodologies for Zoonotic Influenza Viruses in Animals and Human–Animal Interface

Influenza and Other Respiratory Viruses, Volume 19, Issue 11, November 2025.
ABSTRACT In 2009, the World Health Organization (WHO) developed a public health research agenda for influenza to guide researchers and outline directions and priority areas for research on influenza aiming at reducing the burden of seasonal epidemic influenza and the risk and impact of pandemic influenza. The agenda was updated in 2017, but since then,
