Sentinel surveillance may collect data on HIV status and sexual behaviour for populations with high risk behaviours such as sex workers, injecting drug users and men who have sex with men.
Population-based surveys with HIV testing such as Demographic and Health Surveys and AIDS Indicators Surveys provide data on HIV prevalence. These surveys as well as MICS and reproductive health surveys also provide other HIV-related data, such as: knowledge of HIV transmission and prevention, multiple sex partners, use of condom during sexual intercourse with a non-marital, non-cohabiting sexual partner in the last 12 months, and access to antiretroviral therapy.
Integrated Biological and Behavioural Surveillance (IBBS) Surveys can provide data on key populations at higher risk of HIV infection, such as men who have sex with men, sex workers, and people who inject drugs.
Reports from health facilities, including antenatal clinics attended by pregnant women, may provide information on results from HIV-tested blood from sample of patients, and information on access to antiretroviral therapy.
Time use surveys can provide data on time spent caring for household members who are sick or disabled, including household members who are HIV infected. However, data specific to care given to HIV infected persons are difficult to obtain.
