Community and Universal Testing for TB among contacts (CUT-TB) is a 4-year EDCTP funded cluster-randomised pragmatic that is being conduct in South Africa, Tanzania and Lesotho.

CUT-TB aims to measure effectiveness of universal testing compared to standard TB screening for detection of TB among household and community contacts.

Contact tracing: Progress towards the End TB strategy has been slow and unless implementation of effective interventions such as active case finding and TPT are scaled-up, we will not reach such ambitious targets. Active case finding is a key pillar of TB control however adoption of effective interventions such as contact investigation has been sub-optimal.
