Molecular Epidemiology and Evolutionary Analysis of Avian Influenza A(H5) Viruses Circulating in Egypt, 2019–2021

Viruses, 2022
The highly pathogenic avian influenza (HPAI) H5N8 virus was first detected in Egypt in late 2016. Since then, the virus has spread rapidly among different poultry sectors, becoming the dominant HPAI H5 subtype reported in Egypt.

Highly Pathogenic Avian Influenza A(H5N8) Clade 2.3.4.4b Viruses in Satellite-Tracked Wild Ducks, Ningxia, China, 2020

Emerging Infectious Diseases, 2022
During October 2020, we identified 13 highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b viruses from wild ducks in Ningxia, China. These viruses were genetically related to H5N8 viruses circulating mainly in poultry in Europe during early 2020 ...

Development and Evaluation of an Inactivated Influenza A(H5N8) Vaccine

Journal of Pure and Applied Microbiology, 2022
Highly pathogenic avian influenza viruses are circulating in lots of avian species, causing major outbreaks in both wild and domestic poultry. Since its first emergence in 2014, clade 2.3.4.4 H5N8 viruses widely spread in the world resulting in enormous economic losses.

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.

Low Virulence and Lack of Airborne Transmission of the Dutch Highly Pathogenic Avian Influenza Virus H5N8 in Ferrets. [PDF]

PLoS ONE, 2015
Highly pathogenic avian influenza (HPAI) H5N8 viruses that emerged in poultry in East Asia spread to Europe and North America by late 2014. Here we show that the European HPAI H5N8 viruses differ from the Korean and Japanese HPAI H5N8 viruses by several ...

Highly pathogenic avian influenza A subtype H5N8 [PDF]

EFSA Journal, 2014
Abstract Highly pathogenic avian influenza (HPAI) H5N8 outbreaks in poultry farms have been reported in Asia and Europe since January and November 2014, respectively. The entry of HPAI H5N8 into Europe and its subsequent spread within Europe are two separate events with possibly different transmission vectors.

Genetic characterization of highly pathogenic avian influenza A (H5N8) virus isolated from domestic geese in Iraq, 2018

BMC Veterinary Research, 2021
Background Influenza viruses are a continuous threat to avian and mammalian species, causing epidemics and pandemics. After the circulation of H5N1 in 2006, 2015, and 2016 in Iraq, an H5N8 influenza virus emerged in domestic geese in Sulaymaniyah ...
