Evaluation of Community Health Workers' Role in Malaria Vector Control in Urban Kenya: A Four-Month Impact Study

Malaria remains a significant public health issue in urban Kenya, where vector control interventions are crucial for reducing transmission rates. A mixed-methods approach was employed, including surveys and focus group discussions to assess CHW activities and their impact on awareness and behaviour change regarding malaria vector control. CHWs conducted an average of 12 community meetings per month, resulting in a significant increase (p < 0. 05) in the proportion of participants who reported using bed nets (from 40% to 65%). Community health workers played a pivotal role in disseminating information and promoting vector control practices among urban residents. Continuation and expansion of CHW programmes should be supported, with emphasis on training for sustained effectiveness. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
