BACKGROUND
The American trypanosomiasis is the second parasitic disease in importance after paludism and one of the main mechanism of transmission is a blood transfusion. Our objective was to measure the effect the Tripanosoma Cruzi screening test in blood banks in the Mexican Institute of Social Security.
METHODS
Information was obtained from each unit of blood collected. The Tripanosoma cruzi prevalence was calculated only in samples with double reactivity in the blood banks.
RESULTS
Of 71 blood banks, only 26 had been doing T. Cruzi screen; after implementation of integrated services 55 are doing the screening. There were 935 donors with double reactivity to the T. Cruzi test from 230,074 samples. The national prevalence was 0.406%. The seroprevalence was 0.013% to 3.118%.
CONCLUSIONS
The screening of the T. cruzi improved the detection and increased the safety and the prevention of its transmission by blood transfusion.
背景
美洲锥虫病是仅次于疟疾的第二大重要寄生虫病，其主要传播途径之一是输血。我们的目的是评估克氏锥虫筛查试验在墨西哥社会保障局血库中的效果。
方法
收集每单位采集血液的信息。仅在血库中具有双重反应性的样本中计算克氏锥虫患病率。
结果
在71家血库中，只有26家进行克氏锥虫筛查；实施综合服务后，有55家进行筛查。在230,074份样本中，有935名献血者对克氏锥虫检测呈双重反应性。全国患病率为0.406%。血清阳性率为0.013%至3.118%。
结论
克氏锥虫筛查改善了检测效果，提高了安全性，并预防了其通过输血传播。
