Dissecting the role of the HA1-226 #leucine #residue in the #fitness and #airborne #transmission of an A(#H9N2) avian #influenza virus

Source: Journal of Virology, ABSTRACTA better understanding of viral factors that contribute to influenza A virus (IAV) airborne transmission is crucial for pandemic preparedness. A limited capacity for airborne transmission was recently observed in a human A(H9N2) virus isolate (A/Anhui-Lujiang/39/2018, AL/39) that possesses a leucine…

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.
