Sumario:Objectives: Misiones State is situated in the north-east of Argentina. The main objective was to establish the evolution of syphilis in Posadas city (300.000 inhabitants) from 1997 to 2000. Methods: Outpatients were studied at the STD clinics during 1997. Records of all pregnant women with babies due to the months of April to June, from 1997 to 2000 (n = 4700), were studied. Syphilis was confirmed by clinic, epidemiological and laboratory tests (VDRL and FTAABS). Results: Higher incidence of primary syphilis in outpatients was established among 15-19 year-old women and in 20-24 year-old men. The percentages of pregnant women with syphilis were 2.1% (1997), 2.6% (1998), 4.6% (1999) and 3.7% (2000). The most vulnerable age group was 15 to 19 year-old. Geographical distribution of cases changed from four clusters in 1997 to a wide occurrence in all city quarters with lower socioeconomic level (30% of population). Conclusion: Posadas city had an increase in cases of syphilis in pregnant women from 1997 to 1999. This evolution indicates that traditional STD-Aids programs have had no effect on safe sex practices, specially among adolescents. Home by home visits aimed at improving prenatal control as a priority, started in 1999. The incidence of the disease became stable in 2000, but still at a high rate. It is necessary to continue and improve the outreach activities. A cooperative program in these big "twin" cities: Encarnación (Paraguay) and Posadas (Argentina) - will be also of great help for syphilis control in the area.
