ECDC initiated a survey of EU/EEA countries to evaluate preparedness planning and risk mitigation initiatives implemented at the country level for people exposed to highly pathogenic avian influenza virus A(H5N1).
The aim of this survey was to review the expertise, capabilities and capacities for detection and characterisation of avian and other zoonotic influenza viruses in national influenza reference laboratories in the European Union/European Economic Area (EU/EEA), in members of the European Reference Laboratories for influenza (ERLINet), and in EU Enlargement policy countries.
This Threat Assessment Brief considers the risk of infection related to avian influenza A(H5N8) virus to the general population and the occupationally exposed.
A recently published study conducted between 2011 and 2018 in China, and based on surveillance data in pigs, identified an emerging genotype 4 (G4) reassortant Eurasian avian-like (EA) A(H1N1) swine influenza virus that contains internal genes from the human A(H1N1)pdm09 and North American triple-reassortant (TR) lineage-derived internal genes.
