益阳地区无偿献血人群梅毒、艾滋病、丙型肝炎及乙型肝炎感染状况分析

目的回顾性分析益阳市地区无偿献血人群梅毒、艾滋病、丙型肝炎及乙型肝炎感染状况，为提高临床用血安全性提供可参考依据。方法收集从2010年1月～2012年12月益阳市无偿献血人群的资料，进行回顾性总结，分析3年间益阳市地区梅毒、艾滋病、丙型肝炎及乙型肝炎感染情况及变化。结果益阳地区无偿献血人群中梅毒、艾滋病、丙型肝炎及乙型肝炎均有一定感染率，有高危接触者感染风险更高。丙型肝炎感染率呈降低趋势，梅毒、艾滋病及乙型肝炎感染率均呈上升趋势，以梅毒感染率增加最明显，其逐年感染率比较差异具有统计学意义（P〈0．05）。结论无偿献血人群中仍然存在较高梅毒、艾滋病、丙型肝炎及乙型肝炎感染率，且梅毒等部分疾病感染率增加，应加强对献血人群血样的检测，警惕高危接触人群．以保证临床用血安全性，避免医源性感染及疾病传播。
