BACKGROUND. To analyze trends in HIV infection among general population during the last 14 years in Mexico. METHODS. Results of the National Health Survey, 2001 were compared with the Seroepidemiological National Health Survey, 1987. Both surveys were probabilistic, polystage, stratified, cluster household surveys of the civilian, noninstitutionalized adult, adolescent and children population conducted in the 31 states and the Federal District of Mexico. For the 1987 survey 10921 samples from men older than 15 years old were randomly selected. For the 2001 survey 5760 samples from persons older than 15 years old have been analyzed. Samples were examined for HIV antibodies (ELISA and WB). Additionally 2001 samples were screened for syphilis (VDRL and FTabs) and anti-HBc (ELISA). RESULTS. HIV antibodies were present in 4/10921 (.04%) in 1987 as compared to 5/5760 (0.1%) in 2001. Syphilis was found in 198/5760 (3.4%) and Hepatitis B in 251/5760 (4.35%) among 2001 samples. CONCLUSIONS. Although prevalence of HIV antibodies has almost doubled among adult general population between 1987 and 2001, it continues to be low. However, it coexists with an alarmingly high prevalence for other sexually transmitted infections. Prevalence of HIV antibodies may mislead decision takers if considered isolatedly. The case of Mexico illustrates the limitations of using HIV prevalence by itself in concentrated epidemics. Although the risk of HIV infection is present in 1 in 1,000 among adult general population, the risk of other sexually transmitted infections are 34 (syphilis) to 43 (Hepatitis B) times greater. We propose for planning and evaluation purposes the use of STI prevalence indicators plus HIV prevalence in countries with HIV concentrated epidemics. Partially finance by CONACYT MO244-9911
