Secondary objectives - To describe the epidemiological and clinical characteristics of participants infected with HIV-2, and the immuno-virological characteristics of the infection. - To study the clinical and immunological progression of HIV-2 infection and the prognostic factors for this progression. - To study the response (clinical, immuno-virological) to antiretroviral treatment and to contribute to the identification of antiretroviral strategies and combinations best suited to the particularities of the infection. - To allow an evaluation of the management practices of the participants - To provide a clinical and biological database and samples for basic science studies on HIV-2 infection. null France Individuals Patients population Male Female Young Adult (19 to 24 years) Adult (25 to 44 years) Middle Aged (45 to 64 years) Aged (65 to 79 years) Aged, 80 and over (80 years and more) Inclusion Criteria : - HIV-2 infection only, diagnosed by ELISA, confirmed by Western-Blot, - Follow-up in one of the investigator centers, - Age greater than or equal to 18 years, - Extended follow-up possible, residence in France planned for at least one year, - Participant's consent to participate, - Possible ALD (Long Term Disorder) status for the participant, or state medical aid (SMA), or declaration of obtaining SMA at the time of inclusion.
