Isolation and sequence analysis of hemagglutinin gene of Influenza A H1N1 virus from Iranian clinical samples during 2009 pandemic flu
Background: Influenza virus is a globally important respiratory pathogen causing high degree of morbidity and mortality annually. The novel Influenza virus (A/H1N1) which involved many populations of the world in 2009 is a sort of triple reassortment between swine, bird and human viruses. Given the...
