The case definition as well as the systems of classification of the infection due to HIV and AIDS used up to date were reviewed. The limitations of their application in the clinical practice were also mentioned since the first systems were created to establish an epidemiological surveillance of the infection and because of the appareance of AIDS. The role of the definition and of the simplified classification systems that are utilized in countries with limitations of resources where it is not possible to use adequate diagnostic aids is also analyzed here. It was stressed that the utilization of theses systems in medical attention and research leads to the necessity of complementing clinical criteria with the use of efficient progression markers that help to estimate the prognosis and to evaluate the efficiency of the antiretroviral therapeutics. Finally, it was assessed the impact of the alternate immunological and virological markers on the improvement of classification systems.
