本文分析了无锡市区1988～1994年采血血源构成及输血后疟疾发生率,认为单纯靠病史及体检筛选献血员以防止输血疟效果甚差;献血员的预防性服药虽有效,但有一定限度及缺点。以 ELISA 法检测献血员丙肝抗体却能基本防止输血疟发生,考虑其机制为一种交叉反应,值得深入研究,很可能有其实用价值。 This article analyzes the composition of blood collected in Wuxi City from 1988 to 1994 and the incidence of post-transfusion malaria. It is considered that the blood donors are only poorly selected based on medical history and physical examination to prevent blood transfusion. The preventive medication for blood donors is effective, Limits and shortcomings. Using ELISA to detect hepatitis C antibody in blood donors can basically prevent the occurrence of blood transfusion malaria. Considering its mechanism as a kind of cross-reaction, it is worth further studying that it may have its practical value.
