Because of the high risk of both TB and HIV among the household contacts of TB patients and the importance of early case detection for both diseases and especially for DR-TB, improving TB case finding is a high priority. Recent studies have shown that having healthcare workers make multiple visits to the homes of TB patients in order to screen household contacts is a logistically challenging and resource- intensive strategy, and it is not routinely undertaken in most public sector settings in South Africa. One alternative to home visits that could prove effective and affordable is to offer small economic rewards to the household contacts of TB patients who voluntarily present at a healthcare facility for TB symptom screening and optional HIV testing. Economic incentives have been successful in increasing demand for healthcare in a variety of settings, but they have not been tried before as a way to increase uptake of services among patients' contacts, rather than among the diagnosed patients themselves.
