Avian Influenza A(H5N1)|2 September 2024|Cambodia
Swab specimens collected on 17 August arrived at the National Institute of Public Health of Cambodia on 19 August and tested positive for influenza A(H5N1) by quantitative reverse transcription polymerase chain reaction (RT-qPCR) on 20 August. The results were confirmed by the Institut Pasteur du Cambodge (IPC) the same day. The sample was successfully sequenced, and phylogenetic analysis of the haemagglutinin (HA) gene showed the virus to be H5 clade 2.3.2.1c, similar to the viruses circulating in Cambodia and Southeast Asia since 2013-2014. However, its internal genes belong to H5 clade 2.3.4.4b viruses. This novel reassortant influenza A(H5N1) virus has been detected in human cases reported in Cambodia since late 2023.
