The data contribute to a better understanding of the circulation influenza viruses especially in North-Africa.The objective this surveillance was detect severe cases, identify their epidemiological and virological characteristics assess impact on healthcare system.We describe report findings laboratory-based human cases virus other respiratory viruses' infection during three seasons Tunisia.The 2008-09 winter season is underway Tunisia, with co-circulation A/H3N2 (56.25%), A(H1N1) (32.5%), few sporadic B (11.25%). In 2010-11 circulating strains are predominantly 2009 pandemic A(H1N1)pdm09 (70%) (22%). And were sub-typed as unsubtyped A, 5% 3%, respectively. Unlike countries, highest prevalence Yamagata-like lineage has been reported Tunisia (76%) localised into clade B/Bangladesh/3333/2007. year, predominated over (95%).
