Epidemiologic features of HIV infection in three municipalities of inner Rio de Janeiro State, Brazil.
In Brazil relatively little attention is being paid to the study of the features of the spread of the AIDS epidemic towards small cities and rural areas. We report a descriptive study on the epidemiological features of HIV infection among 208 adult patients seen between July 1999 and May 2006 in the municipal HIV/AIDS Programs of three cities of inner Rio de Janeiro State: Saquarema, Santo Antonio de Pádua and Miracema. A portrait of a heterosexual epidemic emerged, with an overall male to female ratio of 1.1. More than 90% were residents of the studied cities, demonstrating a local demand for HIV-related assistance and the importance of municipal HIV/AIDS Programs. Past or current use of snorted cocaine was reported by a quarter of the patients. Older age and male gender were independent predictors of having a diagnosis of AIDS at presentation. The latter is in accordance with a more recent wave of epidemic spread towards female gender. A low frequency of male circumcision, an important determinant of heterosexual HIV transmission, was recorded. Almost 60% of the patients first presented in advanced stages of HIV infection, suggesting the existence of a large pool of undiagnosed cases in the community.
