A survey of occupational blood contact and HIV infection among traditional birth attendants in Rwanda.
OBJECTIVE
To investigate the risk of occupationally acquired HIV infection among traditional birth attendants (TBA) in Rwanda, Africa.


METHODS
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.


RESULTS
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%).


CONCLUSIONS
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.
