#Outbreak Reports: Epidemiological and Genetic Characterization of Three #H9N2 Viruses Causing #Human #Infections — Changsha City, #Hunan Province, #China, April 2025, https://etidiohnew.blogspot.com/2025/11/outbreak-reports-epidemiological-and.html

#Avian #Influenza A(#H9N2) - #Ghana, #WHO D.O.N.: https://www.who.int/emergencies/disease-outbreak-news/item/2024-DON534

On 26 August 2024, the Ghana #IHR NFP notified WHO of 1 confirmed #human #infection with an avian influenza A(H9N2) virus. This marks the first human infection with a zoonotic influenza virus reported from Ghana to WHO. The patient is a #child under five years old, residing in the Upper East region, which is located on the border with Burkina Faso.

An emerging #PB2-627 #polymorphism increases #pandemic #potential of avian #influenza virus by breaking through ANP32 host restriction in #mammalian & avian hosts, BioRxIV: https://www.biorxiv.org/content/10.1101/2024.07.03.601996v4

by screening the global PB2 seq., we discovered a new independent cluster with PB2-627V emerged in the '10s, which is prevalent in various avian, mammalian, & human isolates of AIVs, including #H9N2, #H7N9, #H3N8, 2.3.4.4b #H5N1, and other subtypes.

Large-Scale #Serological #Survey of #Influenza A Virus in South #Korean Wild #Boar (Sus scrofa) https://pubmed.ncbi.nlm.nih.gov/38842623/?utm_source=Feedly&utm_medium=rss&utm_campaign=None&utm_content=1fgJURi2yzLesFml6et0Bb6krzs_FrNIYgPYVFN50JPwVNFg9s&fc=None&ff=20240606155644&v=2.18.0.post9+e462414

Detected subtypes included 23 cases of pandemic 2009 #H1N1, six of human seasonal #H3N2, three of classical swine H1N1, 13 of triple-reassortant swine #H1N2, seven of triple-reassortant swine H3N2, and seven of swine-origin H3N2 variant. Notably, none of the serum samples tested positive for avian IAV subtypes #H3N8, #H5N3, #H7N7, and #H9N2 or canine IAV subtype H3N2.

''Phylogenetic analyses showed that it was a sextuple‐#reassortant virus of #H11N9, #H3N8, #H3N6, #H7N9, #H9N2, and #H6N8 viruses present in #China, similar to the H11N9 strains in #Japan and #Korea during the same period. ''
