19 December, 2024 In the last quarter of 2024, specifically between September 21 and December 6, a total of 657 highly pathogenic avian influenza (HPAI) A(H5N1) and A(H5N5) virus detections were reported in Europe. These detections occurred in both domestic (341 cases) and wild birds (31...
Avian influenzaH5N1public healthseasonal fluviral infectionAsia has been alarmed by the resurgence of avian influenza A (H5N1) in Cambodia in 2024. H5N1 could be swiftly transmitted by wild birds to poultry populations along their migration route via infection. Circulation of...
The rapid mutation of avian influenza virus (AIV) poses a significant threat to both the poultry industry and public health. Herein, we have successfully developed an mRNA-LNPs candidate vaccine for H5 subtype highly pathogenic avian influenza and evalua
The outbreaks of the highly pathogenic avian influenza (HPAI) in 2016–2017 and 2017–2018, caused by novel reassortant clade 2.3.4.4 H5N6 viruses, resulted in the loss of one billion birds in South Korea. Here, we characterized the H5N6 viruses isolated from wild birds in South Korea from ...
Influenza A virus (AIV) circulation was investigated in the Lombardy region, during 2022–2024, in wild ducks (through hunting and sampling of faecal samples within natural parks) and wild birds found dead. Samples were analysed through real-time RT-PCRs for Influenza A virus, H5 and H7. ...

The first report on the isolation of the influenza virus from turkeys with respiratory signs was in the 1960s in the United States. Since then, several outbreaks caused by low-pathogenic (LP) and highly pathogenic avian influenza (HPAI) subtypes, that is, H1, H3, H5, H6, H7, and H9, ...
Since 1997, several epizootic avian influenza viruses (AIVs) have been transmitted to humans, causing diseases and even deaths. The recent emergence of severe human infections with AIV (H7N9) in China has raised concerns about efficient interpersonal vir
