山东省某地区献血员丙型肝炎病毒感染状况调查

目的：了解部分地区献血员丙型肝炎病毒（ＨＣＶ）的感染状况及流行因素。方法：对山东省某地区以自然村为单位整群抽取４３５例有偿献血员进行调查，用酶联免疫吸附方法（ＥＬＩＳＡ）对其血清进行抗－ＨＣＶ检测。结果：献血员ＨＣＶ感染率为２１．１５％（９２／３４５），ＨＣＶ感染率在有献血浆史者为４４．２２％，高于无献血浆史者（９．３８％），１９９５年前献血者（３３．８３％）高于１９９６年后献血者（９．８４％），

Investigation on HCV Infection Among Paid Blood Donors in Some Areas of Shandong Province

Objective To investigate the prevalece and risk factors of HCV infection among blood donors in some areas. Method 435 paid blood donors were selected by using the method of cluster sampling from Sep. 1998 to Mar. 1999. Anti-HCV was detected by enzyme-linked immunosor-bent assay (ELISA). Results The prevalence of HCV in blood donors was 21.15% (92/435). It was 44.22% of the plasma doors which was higher than that of the only blood donors (9.38%). The prevalence of HCV in the blood donors donating blood (plasma) before 1995 was 33.83% ,much higher than that (9.84%) after 1996. It was 24.65% in the donors whose frequency of donating was above once every three months, higher than that (15.67%) of below once every three months. Logistic multivariate analysis showed: history of plasma donation and donating before 1995 were risk factors of HCV infection in blood donors. Conclusion HCV prevalence in paid blood donors is relatively higher.The history of plasma donation and donating before 1995 were main risk factors of HCV infection in this population.
