Background: Uptake of HIV counseling and testing (HCT) among informal sector workers is not well documented.

Objective: To assess HCT practices among clients presenting for HIV services at a market HIV clinic in Kampala, Uganda.

Methods: Between August 1 and September 15, 2009, clients presenting for HIV services at a market HIV clinic were invited to participate in the study. Socio-demographic and HCT data were collected from consenting adults aged 16+ years. Descriptive statistics were performed using STATA version 14.1.

Results: Of 224 individuals who consented to the interview, n=139 62 % were market vendors while n=85 38 % were engaged in other market-related activities. Majority of the respondents, n=165, 73.7 %, had ever tested for HIV; of these, n=148,89.7 % had ever tested for 2+ times. The main reasons for repeat testing were the need to confirm previous HIV test results, n=126, 85.1% and the belief that the previous HIV test results were false, n=35, 23.6 %. Uptake of couples’ HCT was low, n=63, 38.2%, despite the fact that n=200, 89 % had ever heard of couples’ HCT.

Conclusion: These findings indicate high rates of repeat testing but low rates of couples’ HCT uptake in this population.
