A cross-sectional, nationally representative AIDS survey in 2007 was used to compare voluntary blood donors with family replacement donors (FRD) in Kenya. Nearly 18,000 men and women aged 15 to 64 years participated, providing blood samples that were tested for sexually transmitted infections. Approximately 2 percent (445) had donated blood in the year before the survey. Among them, the majority reported voluntary donation (64 percent). Volunteer donors tended to be younger and wealthier than FRDs and reported lower levels of sexual activity and fewer sex partners in the year before the survey. HIV prevalence was 2.6 percent among voluntary donors and 7.4 percent among FRDs (p = 0.07); herpes simplex virus 2 prevalence was 20 percent and 40 percent, respectively (p = 0.001). Voluntary donors comprised 6.5 of every 10 blood donations in 2007, up from 2 in 10 in 2001. Efforts are needed, however, to reduce reliance on FRDs, who are generally subject to less stringent screening practices and thus increase the risk of TTI.
