The feasibility and costs of an active tuberculosis case finding project in Cape Town, South Africa has been explored in a research article by Katharina Kranzer from the London School of Hygiene & Tropical Medicine and colleagues.
The study describes the integration of tuberculosis testing into a mobile HIV testing service for HIV-negative individuals with symptoms suggestive of tuberculosis and all HIV-positive individuals. The mobile testing clinic, named the Tutu Tester after Archbishop Emeritus Desmond Tutu, visits underserviced areas in greater Cape Town and provides testing services for deprived communities. The study demonstrates that active tuberculosis case finding in settings with a high burden of HIV and tuberculosis is feasible and has a high uptake, yield, and treatment success. However, the authors note that further work is required to determine whether mobile active tuberculosis case finding is cost-effective and whether the service can be scaled up.
