Training Community Health Workers for Malaria Control in Northern Ghana: A Comparative Study

Malaria remains a significant public health concern in northern Ghanaian villages, despite ongoing efforts to control its transmission through vector management and community engagement. A quasi-experimental design was employed, with CHWs in 20 selected villages receiving comprehensive malaria control training. Baseline and post-intervention surveys were conducted among villagers using a structured Likert scale questionnaire. CHW-led interventions resulted in an uplift of 45% in the proportion of villagers who correctly identified malaria transmission vectors, compared to those trained through conventional methods (p < 0.001). Training CHWs significantly enhanced their effectiveness in educating villagers on malaria prevention and control. Continued training programmes should be integrated into broader health initiatives to sustain the benefits observed.
