This article presents surveillance data on HIV infection and AIDS in France for 2013, based on mandatory reporting of HIV and AIDS and virological surveillance, as well as trends since 2003. In 2013, 6,220 people (95% CI: [5,759–6,681]) learned they were HIV-positive, including 43% men who have sex with men (MSM), 37% were heterosexuals born abroad, 18% were heterosexuals born in France, and 1% were people who use drugs. Between 2012 and 2013, the number of new diagnoses remained stable, regardless of the mode of transmission. Among the HIV diagnoses in 2013, 39% were early-stage (≥500 CD4/mm³ or primary infection) and 25% were late-stage (<200 CD4/mm³ or AIDS stage). The number of early diagnoses has increased since 2011, and the number of late diagnoses has decreased since 2010, except among MSM, where it has remained stable. In 2013, HIV-2 infections accounted for 1.2% of cases, and HIV-1 infections of non-B subtypes accounted for 42% (a proportion that has remained stable since 2008). The regional disparities observed since 2003 persisted in 2013: the number of new HIV diagnoses per million inhabitants (95 per million) was higher in the French departments of the Americas (908, 239, and 225 in French Guiana, Guadeloupe, and Martinique, respectively) and in Île-de-France (221). In 2013, approximately 1,200 (95% CI: [1,092–1,333]) cases of AIDS were diagnosed, 85% of which were in individuals who had not previously received antiretroviral therapy.
