Abstract__ The Human Immunodeficiency Virus type 1 HIV-1 is classified into genetic groups subtypes and sub-subtypes which show a specific geographic distribution pattern. The HIV-1 epidemic in Italy as in most of the Western Countries has traditionally affected the Intra-venous drug user IDU and Homosexual Homo risk groups and has been sustained by the genetic B subtype. In the last years however the HIV-1 transmission rate among heterosexuals has dramatically increased becoming the prevalent transmission route. In fact while the traditional risk groups have high levels of knowledge and avoid high-risk practices the heterosexuals do not sufficiently perceive the risk of HIV-1 infection. This misperception linked to the growing number of immigrants from nonWestern Countries where non-B clades and circulating recombinant forms CRFs are prevalent is progressively
