Behavioural surveillance or other special surveys. Respondents are asked the following questions: 1. Have you been tested for HIV in the last 12 months? If yes: 2. I don’t want to know the results, but did you receive the results of that test? Whenever possible, data for people who inject drugs should be collected through civil society organizations that have worked closely with this population in the field. Access to survey respondents as well as the data collected from them must remain confidential.
