Background: Early systems of surveillance had helped to generate a response to HIV/AIDS but they were insufficient to meet and monitoring the evolving changes of the epidemic. Second generation surveillance promotes a more comprehensive approach to know trends in prevalence of HIV and other STIs as well as to understand changes in practices and behaviours of most vulnerable populations
Methods: We sistematized the results of the studies about practices and behaviours in vulnerable populations with or without data of HIV prevalence that were made in different areas of our country between 2001 and 2008. Published and not published studies produced by academic, governmental and no-governmental organization were included
Results: While perinatal transmission was not known in the mayority of populations sexual transmission was referred more frequently in all groups.The realization of voluntary HIV testing was more frequent in women, people with higher educational level and individuals reached by prevention or harm reduction programmes.HIV test was made anytime in 51% of the general population.
Conclusions: The heterogeneus methodology of studies and non probabilistic samples limitated the extrapolation of results.There was a preponderance of the population of Metropolitan Area and the samples were mainly conformated by individuals linked to NGOs and therefore with greater access to preventive strategies.
However, the results of these studies contribute for the estimation of HIV prevalence among vulnerable populations and for the design of new investigations and strategies for prevention of HIV and other STIs.
