Ma Y, et al. - Researchers conducted a cluster-randomized controlled trial in 40 communities in Ghana to investigate the impact of community health volunteers (CHVs) on child diarrhea and fever prevalence, as well as examined whether community coverage and duration of home visits influence the impact of the CHV program. Data reported that the prevalence of diarrhea and fever after a 12-month follow-up was 7.0% and 18.4% respectively. No effect of CHVs’ home visits on the prevalence of child diarrhea or fever was found in this analysis. However, childhood infectious disease prevalence may be reduced by CHV programs with high community coverage and regular household contacts of effective duration.
