Detection of Clade 2.3.4.4b Avian Influenza A(H5N8) Virus in Cambodia, 2021

Emerging Infectious Diseases, 2023
In late 2021, highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b viruses were detected in domestic ducks in poultry markets in Cambodia. Surveillance, biosafety, and biosecurity efforts should be bolstered along the poultry value chain to limit spread and infection risk at the animal-human interface.

Spreading of the High-Pathogenicity Avian Influenza (H5N1) Virus of Clade 2.3.4.4b into Uruguay

Viruses, 2023
Background: Avian influenza viruses (genus Alphainfluenzavirus, family Orthomyxoviridae) infect avian and mammal hosts. In 2022, the high pathogenicity avian influenza virus (H5N1) spread to South America, resulting in the loss of thousands of wild birds, including endangered species, and severely impacting the global poultry industry.

Transmission of lethal H5N1 clade 2.3.4.4b avian influenza in ferrets

, 2023
Abstract Highly pathogenic avian influenza viruses of the H5N1 subtype are highly lethal in many avian species. Since 2014, viruses of the genetically distinct clade 2.3.4.4 have been circulating in Eurasia, Africa and briefly in North America, killing millions of wild and domestic birds. In December, 2021 clade 2.3.4.4b H5N1 viruses were first
