A subset of men, 81 in all, returned for a second VCT episode after an initial negative HIV test. Of these, 6 seroconverted between their first and a subsequent VCT episode, allowing for an estimate of incident infections. Using a midpoint assumption for seroconversion and a 100 person/years at risk approach, the estimated incidence among repeat testers was 8.2/100PY, 95% CI 3.7/100PY, 18.3/100PY. It is likely that repeat testers represent a relatively high risk subset of MSM, but the number of incidence cases was too small to assess risk differences.
