Wide circulation of HIV-infection/AIDS is a socially important problem for the majority of the countries of the world now. Against the background of the remaining high rates of infection spread beyond the borders of risk groups, a series of the negative phenomena aggravating an epidemiological situation on HIV-infection and other socially important diseases is observed (tuberculosis, hepatitises, etc.): depression of the general indicators of health of the population, urbanization, complicating of life rhythm, wide circulation of dependences on psychoactive agents, and, above all – serious transformation of institute of family, liberalization of sex behavior, of traditional family values. Now in representations of Russians the typical HIV-positive-a young childless and single man regardless of sexual orientation who is living in the large city, having an average special educations or being in process of its receiving whith level of income comparable to average one. The HIV-positive has been infected as a result of a youth error (unprotected sexual contact or the intravenous use of drugs) and lives with this diagnosis several years, leads a risk-free life more often, at the same time usually hiding the diagnosis and separated from social communications. Existence of this diagnosis involves social trouble and the social not approved behavior, but if the disease affects the loved one, many Russians are potentially ready to give moral and psychological support (56%), financial support (including in purchase of drugs), the help in search of necessary experts and visit of the medical organizations (6,9%) and also to care for the HIV infected and their children (6%). According to authors, the widespread negative perception of people with “HIV-infection“ diagnosis is in many respects caused by insufficient informing the population on HIV-infection/AIDS problems.
