目的对单采血浆供血人群艾滋病病毒(humani mmunodeficiency virus,HIV)感染暴发进行溯源。方法 1995年3月,对单采血浆供血者采集血标本进行HIV筛查,对1990年1月～1995年2月单采血浆供血者和受血者血清标本库的标本进行回顾性检测。结果 1995年3月,永清、固安和霸州单采血浆供血者HIV感染率为2.48%。1990年1月至1995年2月血清库保存的单采血浆供血者和与其相关疾病的血清标本检测HIV抗体均为阴性。结论廊坊地区发生的单采血浆供血者HIV感染暴发流行可能始于1994年10月前后。
Objective To trace the outbreak of HIV infection in apheresis plasma. Methods In March 1995, blood samples were collected from apheresis plasma donors for HIV screening. Specimens of serum samples from blood donors and recipients from January 1990 to February 1995 were retrospectively reviewed. Results In March 1995, the prevalence of HIV infection in apheresis patients in Yongqing, Gu’an and Bazhou was 2.48%. From January 1990 to February 1995, serum samples from the serum pool of preserved apheresis and related serum samples were negative for HIV antibody detection. Conclusions The outbreak of HIV infection in apheresis plasma in Langfang area may begin around October 1994.
