Community Health Workers' Role in Tuberculosis Control: An Analysis in South African Rural Settings

Tuberculosis (TB) remains a significant public health concern in South Africa, particularly in rural areas where access to healthcare services is limited. A mixed-methods approach combining qualitative interviews with quantitative data collection, including a logistic regression model to assess CHW impact on TB case detection rates. Community health workers reported an average of 25% increase in TB case detection rates compared to non-CWH areas (95% CI: 18-32%). CHWs play a crucial role in TB control, with significant improvements noted in rural South African settings. Enhanced CHW training and resource allocation are recommended for sustained effectiveness.
