To investigate the risk of occupationally acquired HIV infection among traditional birth attendants (TBA) in Rwanda, Africa.
A serosurvey was conducted among 219 TBA practicing in a rural but densely populated area in southern Rwanda. Each TBA was interviewed about sociodemographic information, work-related habits and practices, and presence of nonoccupational risk factors for HIV infection. The frequency of skin exposure to HIV-infected blood was estimated for each TBA from HIV seroprevalence data collected previously from pregnant women stratified by the geographic zones in which the TBA practiced.
Four TBA (1.8%) tested HIV-1-antibody-positive; all four had reported nonoccupational risk factors for HIV infection. We estimated that the 215 HIV-negative TBA had 2234 potentially infectious blood-skin contacts out of a total of approximately 35,000 deliveries assisted in the past 5 years. However, we found no evidence of HIV infection caused by occupational blood contact (none out of 2234; upper limit of the 95% confidence interval because of one potentially infectious blood-skin contact = 0.2%).
Although these findings may not be universal to all TBA in Africa, the risk of occupationally acquired HIV infection among TBA appears small. The high frequency of blood-skin contact among TBA in Rwanda highlights the need to include infection control precautions in the training of TBA.
调查非洲卢旺达传统助产士职业性感染艾滋病毒的风险。
对卢旺达南部一个农村但人口密集地区从业的219名传统助产士进行了血清学调查。每位传统助产士都接受了关于社会人口学信息、工作相关习惯和做法以及艾滋病毒感染非职业风险因素的访谈。根据先前从按传统助产士执业地理区域分层的孕妇中收集的艾滋病毒血清流行率数据,估算每位传统助产士皮肤接触艾滋病毒感染血液的频率。
4名传统助产士(1.8%)艾滋病毒-1抗体检测呈阳性;这4人都报告了艾滋病毒感染的非职业风险因素。我们估计,在过去5年协助的约35000例分娩中,215名艾滋病毒阴性的传统助产士有2234次潜在的感染性血液-皮肤接触。然而,我们没有发现职业性血液接触导致艾滋病毒感染的证据(2234次接触中无感染;因一次潜在的感染性血液-皮肤接触,95%置信区间上限 = 0.2%)。
尽管这些发现可能不适用于非洲所有传统助产士,但传统助产士职业性感染艾滋病毒的风险似乎较小。卢旺达传统助产士血液-皮肤接触的高频率凸显了在传统助产士培训中纳入感染控制预防措施的必要性。
