The Effectiveness of Community-Based Health Worker Programmes in Preventing Tuberculosis Among Urban Youth in Cape Town: An African Perspective

Urban youth in Cape Town, South Africa face high risk of tuberculosis (TB), influenced by socio-economic factors and inadequate access to healthcare services. A mixed-methods approach combining quantitative survey data with qualitative interviews and focus groups to assess programme implementation and participant perceptions. Community workers facilitated early diagnosis through regular health check-ups, resulting in a 20% reduction in TB incidence among surveyed youth over two years (95% CI: 15-24%). The community-based health worker programmes significantly improved TB prevention outcomes but require further evaluation of long-term efficacy and sustainability. Expand programme reach to all urban youth, integrate digital platforms for remote monitoring, and conduct longitudinal studies to monitor sustained improvements in TB incidence rates.
