Highly pathogenic avian influenza (HPAI) H5Nx viruses have continually undergone multiple evolutionary dynamics for the generation of various clades, subclades, and genotypes where 2.3.2.2c, and 2.3.4.4 become predominant and co-circulating in Vietnam from 2014 to date.

Highly pathogenic avian influenza viruses (HPAIVs) of H5 subtype pose a great threat to the poultry industry and human health. In recent years, H5N6 subtype has rapidly replaced H5N1 as the most predominate HPAIV subtype circulating in domestic poultry in China. In this study, we describe the genetic and phylogenetic characteristics of a prevalent H5N6 strain in Guangdong, China.

The poultry industry in Egypt has been suffering from endemic highly pathogenic avian influenza (HPAI) virus, subtype H5N1 since 2006. However, the emergence of H9N2, H5N8, and H5N2 in 2011, 2016, and 2019 respectively, has aggravated the situation. Our objective was to evaluate how effective are the mitigation strategies by a Quantitative Risk Assessment (QRA) model which used daily outbreak data of HPAI-H5N1 subtype in Egypt, stratified by different successive epidemic waves from 2006 to 2016.

Several outbreaks of highly pathogenic avian influenza (HPAI) caused by influenza A virus of subtype H5N8 have been reported in wild birds and poultry in Europe during autumn 2020. Norway is one of the few countries in Europe that had not previously detected HPAI virus, despite widespread active monitoring of both domestic and wild birds since 2005.

Aquatic waterfowl, particularly those in the order Anseriformes and Charadriiformes, are the ecological reservoir of avian influenza viruses (AIVs). Dabbling ducks play a recognized role in the maintenance and transmission of AIVs.

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 Province, Iraq. This study analyzed the genetic characteristics of the Iraqi H5N8 viruses.

The pandemic threat of influenza has attracted great attention worldwide. To assist public health decision-makers, new suites of tools are needed to rapidly process and combine viral information retrieved from public-domain databases for a better risk assessment.

An improved reverse genetics system for influenza A virus generation and its implications for vaccine production present an improved system for the generation of influenza viruses that allows the easy and repro ducible production of vaccine viruses in vero cells. Application of this system may be especially advantageous in situations of outbreaks of highly pathogenic avian influenza viruses.

The highly pathogenic H5N1 is a major avian pathogen that crosses species barriers and seriously affects humans as well as some mammals. It mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences. Methods: Nasal swabs were collected from donkeys suffered from respiratory distress. The virus was isolated from the pooled nasal swabs in specific pathogen free embryonated chicken eggs (SPF-ECE).

Poultry in 2006 our country has about 215 million children. Song epidemic of Highly Pathogenic Avian Influenza (HPAI) caused by H5N1 virus broke out in almost all provinces in the country from early 2004 to far as millions of birds have been destroyed. H5N1 epidemic has caused great impact both in terms economic and social area. The question arises: how to limit this dangerous disease and war translated by vaccine inoculation has to be a useful tool? This study aims to classify poultry production system with the obstacles encountered in each system, especially the risk of disease...
