Emergence and Rapid Spread of a New Reassortant High Pathogenicity H5N1 Clade 2.3.4.4b Avian Influenza Virus in Nigeria. [PDF]

Influenza Other Respir Viruses
ABSTRACT Over the past two decades, West Africa has experienced recurrent incursions of Goose/Guangdong‐lineage highly pathogenic avian influenza (HPAI) A(H5N1), with Nigeria as a hotspot for repeated introductions and sustained circulation. Since 2021, European‐origin clade 2.3.4.4b H5Nx genotypes, particularly EA‐2020‐C, have predominated in regional

Exploring the responses of smallscale poultry keepers to avian influenza regulations and guidance in the United Kingdom, with recommendations for improved biosecurity messaging

Heliyon, 2023
Understanding how smallscale (‘backyard’) poultry keepers interpret and respond to governmental directives designed to reduce the transmission of highly pathogenic avian influenza (HPAI) is of paramount importance in preparing for future HPAI outbreaks ...

Highly Pathogenic Avian Influenza Viruses at the Wild–Domestic Bird Interface in Europe: Future Directions for Research and Surveillance

Viruses, 2021
Highly pathogenic avian influenza (HPAI) outbreaks in wild birds and poultry are no longer a rare phenomenon in Europe. In the past 15 years, HPAI outbreaks—in particular those caused by H5 viruses derived from the A/Goose/Guangdong/1/1996 lineage that ...

H7N9 Influenza Virus Containing a Polybasic HA Cleavage Site Requires Minimal Host Adaptation to Obtain a Highly Pathogenic Disease Phenotype in Mice

Viruses, 2020
Low pathogenic avian influenza (LPAI) H7N9 viruses have recently evolved to gain a polybasic cleavage site in the hemagglutinin (HA) protein, resulting in variants with increased lethality in poultry that meet the criteria for highly pathogenic avian ...

REGIONAL RISK ASSESSMENT OF HIGHLY PATHOGENIC AVIAN INFLUENZA IN THE BORDER OF INDONESIA AND MALAYSIA: A SOCIO ECONOMIC PERSPECTIVE

Sepa, 2017
The result  of  the  study  shows  that  the  extent  of  both  active  and  passive surveillance was still low due to large coverage area and lack of report cases of  Highly Pathogenic Avian Influenza (HPAI)  from poultry farmers.

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.
