Influenza A virus (IAV) is a negative-stranded RNA virus belonging to the Orthomyxoviridae family. The IAV genome is divided into eight segments that encode 11 viral proteins in total (HA, NA, M1, M2, NP, NS1, NS2, PA, PB1, PB2, and PB1-F2). The viral envelope of IAV contains the transmembrane proteins HA, NA, and M2 [1].
