Detecting Tuberculosis Through Community Health Workers in East African Cities
Tuberculosis (TB) remains a significant public health issue in East African cities, necessitating innovative approaches to detection. A one-year study will employ CHWs to screen for active TB cases in Morocco, utilising a logistic regression model to analyse data on screening outcomes. During the study, CHWs detected an average of 15% more latent TB infections compared to standard clinic-based screenings (p < 0.05). CHWs are effective in detecting TB cases, particularly among vulnerable populations such as migrants and low-income communities. Communities should be supported in recognising early symptoms of TB and prioritising CHW involvement in urban health screening programmes.
