This article presents the status of HIV infection and AIDS in France in 2011, based on mandatory reporting of HIV and AIDS and virological surveillance. Approximately 6,100 people [95% CI 5,716–6,460] were diagnosed with HIV in 2011, including 39% men who have sex with men (MSM), 40% were foreign-born heterosexuals, 18% were French-born heterosexuals, and 1% were people who use drugs. Since 2003, there has been an increase in new diagnoses among MSM and among people aged 50 and older, and a decrease among foreign-born heterosexuals. Among the new HIV diagnoses in 2011, 29% were late-stage and 35% were early-stage. Late diagnoses mainly concern people aged 50 and older and heterosexual men. In 2011, 1,400 [95% CI 1,279–1,517] cases of AIDS were diagnosed, most of whom had not previously received antiretroviral treatment. The regional disparities observed since 2003 persisted in 2011: relative to the population, the number of new HIV diagnoses was higher in the French departments of French Guiana and in Île-de-France.
