Dairy cows inoculated with highly pathogenic avian influenza virus H5N1. [PDF]

Nature
Abstract Highly pathogenic avian influenza (HPAI) H5N1 haemagglutinin clade 2.3.4.4b was detected in the USA in 2021. These HPAI viruses caused mortality events in poultry, wild birds and wild mammals. On 25 March 2024, HPAI H5N1 clade 2.3.4.4b was confirmed in a dairy cow in Texas in response to a multistate investigation into milk ...

Spillover of highly pathogenic avian influenza H5N1 virus to dairy cattle

Nature
The highly pathogenic avian influenza (HPAI) H5N1 virus clade 2.3.4.4b has caused the death of millions of domestic birds and thousands of wild birds in the USA since January 2022 (refs. 1-4). Throughout this outbreak, spillovers to mammals have been frequently documented5-12.

Avian influenza A (H7N9) virus: from low pathogenic to highly pathogenic [PDF]

Frontiers of Medicine, 2021
AbstractThe avian influenza A (H7N9) virus is a zoonotic virus that is closely associated with live poultry markets. It has caused infections in humans in China since 2013. Five waves of the H7N9 influenza epidemic occurred in China between March 2013 and September 2017.

First detection of highly pathogenic avian influenza virus in Norway [PDF]

BMC Veterinary Research, 2021
Abstract Background 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 ...

Pathogenicity of highly pathogenic avian influenza virus in mammals [PDF]

Vaccine, 2008
In recent years, there has been an increase in outbreaks of highly pathogenic avian influenza (HPAI) in poultry. Occasionally, these outbreaks have resulted in transmission of influenza viruses to humans and other mammals, with symptoms ranging from conjunctivitis to pneumonia and death.

Highly Pathogenic Avian Influenza Virus, Midwestern United States [PDF]

Emerging Infectious Diseases, 2016
To the Editor: Novel highly pathogenic avian influenza (HPAI) viruses of subtypes H5N2, H5N8, and H5N1 have recently caused numerous outbreaks in commercial poultry farms in the United States and Canada (1). Risk for zoonotic transmission is low; humans are affected primarily from the extensive economic repercussions of suspending poultry-farming ...

Highly Pathogenic Avian Influenza A(H5N8) Virus, Cameroon, 2017 [PDF]

Emerging Infectious Diseases, 2018
Highly pathogenic avian influenza A(H5N8) viruses of clade 2.3.4.4 spread into West Africa in late 2016 during the autumn bird migration. Genetic characterization of the complete genome of these viruses detected in wild and domestic birds in Cameroon in January 2017 demonstrated the occurrence of multiple virus introductions.

Highly Pathogenic Avian Influenza (H5N1) Virus in Feathers [PDF]

Veterinary Pathology, 2016
H5N1 highly pathogenic avian influenza (HPAI) virus causes high mortality of infected birds, with infection in multiple organs, including in feathers. Feathers have been proposed as samples for diagnosis of HPAI infection in birds, and this study is part of a broader investigation validating the use of feathers for diagnostic purposes.

The episodic resurgence of highly pathogenic avian influenza H5 virus

Nature, 2022
AbstractHighly pathogenic avian influenza (HPAI) H5N1 activity has intensified globally since 2021, replacing the dominant clade 2.3.4.4 H5N8 virus. H5N1 viruses have spread rapidly to four continents, causing increasing reports of mass mortality in wild birds and poultry.

Newly Emergent Highly Pathogenic H5N9 Subtype Avian Influenza A Virus [PDF]

Journal of Virology, 2015
ABSTRACT The novel H7N9 avian influenza virus (AIV) was demonstrated to cause severe human respiratory infections in China. Here, we examined poultry specimens from live bird markets linked to human H7N9 infection in Hangzhou, China. Metagenomic sequencing revealed mixed subtypes (H5, H7, H9, N1, N2, and N9).
