Notes: Full sample includes respondents who accepted a test for HIV in 2004 and have basic demographic data. Follow-up sample includes respondents in Balaka and Rumphi who tested and were reinterviewed in 2005. HIV prevalence rates do not include 14 respondents with indeterminate diagnoses. Other STI prevalence rates do not include 83 respondents with indeterminate diagnoses. Trichomoniasis was tested only among women. Respondents were asked about sexual acts per month only during the nurses’ survey in Balaka. The monetary incentive is a sum of an incentive for learning HIV results and an incentive for learning other STI results (in Mchinji and Balaka). Distance from assigned testing centers to respondents’ homes is a straight-line spherical distance measured in kilometers. Reported having sex with more than one partner does not include those who did not report having sex in the follow-up survey. Sexual acts per month was asked only among a subset of respondents between the baseline survey and time of the VCT.
