某地既往有偿供血人群HIV感染流行病学调查分析

Epidemiological Survey and Analysis of HIV Prevalence Among Former Paid Blood Donors in a Certain District of Southeast of Henan

目的 摸清豫东南某地既往有偿供血人群（FPD）艾滋病病毒（HIV）感染状况，为制定艾滋病预防控制策略和措施提供科学依据。方法 对所有既往有偿供血员进行普查，同时采血进行HIV抗体检测。对HIV确认阳性者进行CD4^＋T淋巴细胞计数检测。结果 共调查既往有偿供血员4351人，其中死亡271人，实际检测人数为3985人，检出HIV感染者693例，感染率为17．39％。男女性别比为0．87：1，20-49岁年龄组占85．28％。CD4^＋〈200／μl者175例，占全部检测者的26．48％。结论 通过普查，基本弄清了既往有偿供血员的HIV感染状况。经血传播途径已被阻断，性传播和母婴传播将可能成为既往有偿供血地区HIV感染的主要传播途径，应采取综合措施遏制其进一步扩散蔓延。
