Trypanosoma cruzi infection was studied in 1,298 sera samples of blood banks from 7 capital departments of Bolivia, using the immunofluorescence test (IFI) and Enzyme Linked Immunosorbent Assay (ELISA). The percentages of positivity in these 7 departments have an average of 28% and are distributed as follows: Sta. Cruz 51%, Tarija 45%, Cochabamba 28%, Sucre 39%, La Paz 4.9%, Oruro 6% and Potosi 24%. The prevalence is related with the altitude levels of the different departments. However in Potosi (3,945 m) we found a 24% of prevalence, probably due to the proximity of endemic valleys to the city. The authors suggest a strict control in blood donors since there exists a great risk of infection.
使用免疫荧光试验（IFI）和酶联免疫吸附测定（ELISA），对来自玻利维亚7个省会城市血库的1298份血清样本进行了克氏锥虫感染研究。这7个城市的阳性率平均为28%，分布如下：圣克鲁斯51%，塔里哈45%，科恰班巴28%，苏克雷39%，拉巴斯4.9%，奥鲁罗6%，波托西24%。患病率与不同城市的海拔高度有关。然而，在波托西（海拔3945米），我们发现患病率为24%，这可能是由于该城市附近存在地方性山谷。作者建议对献血者进行严格管控，因为存在很大的感染风险。
