The study will also test how safe and effective it is to start TB treatment at about the same time as HIV treatment even when TB infection has not been found. The study will collect information about diet, whether (and when) people in the study become sicker or die, how well their HIV is controlled, how they are feeling, how they are taking their medications, whether it matters where they live or what kind of HIV and TB care is standard, how many people are diagnosed with TB while in the study, and how the cost of the two treatment options on a national level could be compared.
