After the interview, the oral fluid sample was obtained and the study participants were remunerated at different levels (between 5–10 USD) as determined by the partner CBO for their time and transportation costs. To maintain confidentiality and anonymity of the participants in the study, two separate rooms were required to ensure that the person reading the test result did not make direct contact with the respondent. Instead, nontraceable alphanumeric participant codes linked the HIV screening data to the surveys.
