| Summary: | Durante el periodo de Octubre de 1991 a Marzo de 1992, se tomaron 3419 muestras de donadores de sangre de 12 localidades rurales y de 8 hospitales urbanos a los que se les realizo un estúdio serológico mediante la reacción de hemaglutinación indirecta encontrándose anticuerpos contra Trypanosoma cruzi en 44 indivíduos 39 masculinosy 5 femininos. El 90,9% de donantes fueron masculinos. De acuerdo a su procedencia, el 73,5% fué del área urbana y el 26,5% del área rural. De acuerdo a los resultados el riesgo de transmisión de T. cruzi por transfusión sanguinea está latente por la creciente urbanización de la enfermedad de Chagas. A Chagas Disease serological study was done frorn October 1991 to March 1992 and 3419 samples were takenfrom people who donated blood at 12 county areas of Jalisco, México and 8 urban hospitais, by means of indirect hemagglutination reaction. The results indicate that: 73.5% of the donors were from urban area, 26.5% were from rural areas; 1.28% of the donors (N=44) were considered infected. Thirty nine of them (1.14) were males and 5 females. According to the above mentioned data, we can confirm that the risk of transmission of Trypanosoma cruzi can occur by blood transfusion and this is potentially latent because of the growing urbanization of Chagas disease.
