 The Home-based AIDS care program pilot project delivers and monitors antiretroviral ARV and tuberculosis TB medications at the homes of 1,000 people with HIV living in a rural area of Uganda. This study is evaluating how well this program reduces illness and prolongs the life of participants, changes sexual behavior, influences levels of adherence to medication, affects aspects of perceived stigma by participants and their communities, and other operational components of the program including cost-effectiveness. This study is evaluating the hypothesis that frequent home visits by a trained lay person with a standard questionnaire is equivalent in terms of health outcomes to frequent viral load and CD4 cell count measurements.
