Objectives We assessed the impact of water, hygiene and sanitation (WASH), maternal, new‐born and child health (MNCH), nutrition and early childhood development (ECD) on diarrhoea and microbial quality of water in a resource‐constrained rural setting in Kenya. Methods Through a controlled intervention study, we tested faecal and water samples collected from both the intervention and control sites before and after the interventions using microbiological, immunological and molecular assays to determine the prevalence of diarrhoeagenic agents and microbial quality of water. Data from the hospital registers were used to estimate all‐cause diarrhoea prevalence. Results After the interventions, we observed a 58.2% (95% CI: 39.4–75.3) decline in all‐cause diarrhoea in the intervention site versus a 22.2% (95% CI: 5.9–49.4) reduction of the same in the control site. Besides rotavirus and pathogenic Escherichia coli, the rate of isolation of other diarrhoea‐causing bacteria declined substantially in the intervention site. The microbial quality of community and household water improved considerably in both the intervention (81.9%; 95% CI: 74.5%–87.8%) and control (72.5%; 95% CI: 64.2%–80.5%) sites with the relative improvements in the intervention site being slightly larger. Conclusions The integrated WASH, MNCH, nutrition and ECD interventions resulted in notable decline in all‐cause diarrhoea and improvements in water quality in the rural resource‐limited population in Kenya. This indicates a direct public health impact of the interventions and provides early evidence for public health policy makers to support the sustained implementation of these interventions. |
