TB contact tracing helps save lives – this is how it works in SA
Tracing the close contacts of people ill with tuberculosis (TB) and offering them TB preventive therapy is part of South Africa’s strategy to fight TB. A recent analysis found that such an approach of tracing household contacts and providing them with TB preventive treatment is cost-effective and would – by 2025 – cut deaths by 35% among household contacts of all ages and people living with HIV. In light of these new findings, Tiyese Jeranji assesses the state of contact tracing in South Africa’s public healthcare system.
