Summary In Uruguay seroprevalence of HIV, hepatitis B and C virus infections are clearly higher in populations at risk. An appropiate management of these infections requires kowledge of these conditiones and their posible causes. The aim of the paper is to determine the prevalence of HIV, hepatitis B and C virus infections among intravenous drug users, older than 18 years, living in Montevideo metropolitan area in 2003; and to analize the influence of intravenous drugs, sexual practices and other behaviours on this prevalence. A sample of 200 users living in the metropolitan area of Montevideo, older than 18 years, that started injections after 1980 was selected by a snowball method from October to December 2003. A prevalence study was designed using primary data, by interviews and serologic studies. Risk practices were analized by relative prevalence (RP) and 95 percent confidence interval. Chi-square Mantel Haenszel Statistics was used to determine statistics associations (p<0.10). Prevalence findings were as follow: 18,5% of HIV virus, 19,5% of hepatitis B, and 21,5% of hepatitis C virus; 33% presented some infections, 15% presented one, 9.5% two and 8,5% up to three. For all infections, the use of injecting drugs at least once a week, consumption over two years, to share syringes and needles, to reuse syringes, to have a sexual partner with HIV or AIDS, having been in prison are risk factors for infection. Prevalences were lower than in other countries of the region; however, one third of injecting drug users present some of these infections, associated with risk practices.
