Multiple infections with H5N8 subtype high pathogenicity avian influenza viruses in a feral mallard. [PDF]

J Vet Med Sci, 2023
During the 2020-2021 winter, Eurasian countries experienced large outbreaks caused by the clade 2.3.4.4b H5N8 subtype high pathogenicity avian influenza viruses (HPAIVs) in the wild bird populations. At least seven gene constellations have been found in the causal HPAIVs. When and where the various HPAIVs emerged remains unclear.

Clade 2.3.4.4b H5N8 Subtype Avian Influenza Viruses Were Identified from the Common Crane Wintering in Yunnan Province, China. [PDF]

Viruses, 2022
The seasonal migration of wild aquatic birds plays a critical role in the maintenance, transmission, and incursion of the avian influenza virus (AIV). AIV surveillance was performed during 2020–2021 in two national nature reserves with abundant wild bird resources in Yunnan, China.

Complete analysis of the H5 hemagglutinin and N8 neuraminidase phylogenetic trees reveals that the H5N8 subtype has been produced by multiple reassortment events [PDF]

F1000Research, 2016
The analysis of the complete H5 hemagglutinin and H8 neuraminidase phylogenetic trees presented in this paper shows that the H5N8 avian influenza has been generated by multiple reassortment events.

Spatial and Temporal Characteristic Analysis and Risk Assessment of Global Highly Pathogenic Avian Influenza H5N8 Subtype. [PDF]

Transbound Emerg Dis
H5N8 HPAI is a highly infectious avian disease that now poses a serious threat and potential risk to poultry farming, wild birds, and public health. In this study, to investigate the seasonality and transmission directionality of global H5N8 HPAI, the spatial and temporal analysis of H5N8 HPAI was conducted using time series decomposition and ...

Detection of Two High Pathogenicity Avian Influenza Virus (HPAIV) Subtypes, H5N1 and H5N5, in a Mass Mortality Event in Wild Seabirds and Co-Location With Dead Seals. [PDF]

Transbound Emerg Dis
H5Nx Clade 2.3.4.4b high pathogenicity avian influenza viruses (HPAIVs) have been detected repeatedly in Great Britain (GB) since autumn 2020, with H5N1 dominating detections but with low level detection of H5N5 during 2025. Globally, these viruses have caused mass mortalities in captive and wild avian and mammalian populations, including terrestrial ...

Temporal Dynamics of Influenza A(H5N1) Subtype before and after the Emergence of H5N8 [PDF]

Viruses, 2021
Highly pathogenic avian influenza (HPAI) viruses continue to circulate worldwide, causing numerous outbreaks among bird species and severe public health concerns. H5N1 and H5N8 are the two most fundamental HPAI subtypes detected in birds in the last two decades.
