Despite public health campaigns and epidemiological surveillance activities, Chagas
disease remains a major health problem in Latin America. According to data from the
World Health Organization, there are approximately 7-8 million people infected with
Trypanosoma cruzi worldwide, a large percentage of which in Latin
America. This study aims to examine the serological profile of blood donors in blood
banks of Hemominas hematology center, in the town of Ituiutaba, Minas Gerais State,
Brazil. The study sample consisted of 53,941 blood donors, which were grouped
according to gender and age. Sample collections were performed from January 1991 to
December 2011, and 277 donors (0.5%) were considered serologically ineligible due to
Chagas disease. Analysis of data showed no significant difference between genders. As
for age, the highest proportion of ineligible donors was from 40 to 49 years (30%),
and there was a positive correlation between increasing age and the percentage of
patients seropositive for Chagas disease. Therefore, adopting strategies that allow
the safe identification of donors with positive serology for Chagas disease is
essential to reduce or eliminate indeterminate serological results.
