Zoonotic influenza - Annual Epidemiological Report 2024

Nine countries reported sporadic human infections with avian influenza virus subtypes A(H5N1), A(H5N2), A(H5N6), A(H5Nx), A(H9N2), A(H10N3) for 2024. Four countries reported human infections with influenza A(H1N1) variant (v), A(H1N2)v and A(H3N2)v viruses of swine origin for 2024.

No human cases of infection with avian influenza viruses or influenza variant virus of swine origin were reported in the EU/EEA in 2024. Considering the widespread transmission of zoonotic influenza viruses in animal populations, reported transmission to humans with zoonotic influenza viruses remains infrequent.
