A tabular dataset containing information provided by 99 HIV-positive individuals – men and women aged 18 or above who had a low CD4 count and were not yet on TB or HIV treatment - enrolled in the TB FastTrack trial, a cluster randomised trial to establish the direct and indirect costs of illness incurred at the patient/household level. Data was collected through patient interviews conducted at the health facility where they were receiving treatment in North West Limpopo and Gauteng provinces between June 2014 and March 2015. The dataset contains 450+ variables, including details on quantity of visits, time spent in seeking care, direct medical and non-medical costs incurred, and individual and estimated household income. Household income was established using 4 approaches: (1) self-reported (detail), (2) self-reported (brackets), (3) by matching through an asset index, and (4) national average income
