MEZA, Graciela. Seroprevalence of Chagas disease in pregnant women of the Cordillera department before and after the implementation of prenatal control of Chagas in the periods 1997 and 2011. Mem. Inst. Investig. Cienc. Salud [online]. 2016, vol.14, n.3, pp.73-80. ISSN 1812-9528.  https://doi.org/10.18004/mem.iics/1812-9528/2016.014(03)73-080.

Chagas disease is caused by the Trypanosomacruzi parasite, affects approximately 10 millons individuals worldwide and is present in almost all Central and South America. In Paraguay, 150,000 people are estimated to be infected, 61,000 of them are women in reproductive age and about 600 congenitally infected children would be born per year. The Cordillera department is an endemic area of the Oriental Region of the country, where seroprevalence in pregnant women in the 90's was around 12%. This retrospective transversal descriptive study was designed to determine the seroprevalence of Chagas disease in pregnant women of the Cordillera department that attended prenatal control during 1997 and 2011. Analysis of the database of pregnant women of the Cordillera department was carried out. Serology for T. cruzi of 7,898 pregnant women performed in 5 laboratories corresponding to 20 districts of the Cordillera was analyzed. The prevalence of T.cruzi infection in pregnant women of this department in the year 1997 was 15% and in 2011 it was 6%, which indicates a reduction of 9%. The collected information contributes to the prenatal control system of the disease in the III Sanitary Region of the Cordillera department, since it showed the efficiency of the prenatal diagnosis system and the methods of prevention implemented by the Ministry of Public Health.
