Sabrina Haque e outros, 2022 · Npj Clean Water
Integrating household water filter distribution and promotion into Rwanda's community hygiene clubs reduced the prevalence of detectable E. coli in drinking water samples by 20% (PR 0.80).

The intervention reduced the proportion of drinking water with detectable E. coli by 20% (PR 0.80, 95% CI, 0.74–0.87, p value < 0.001) compared to the control.
Contexto
What changed: Households received tabletop LifeStraw Family 2.0 purifiers alongside educational and maintenance visits by community hygiene facilitators. Comparison: 30 control villages receiving only standard environmental health hygiene promotion without filters. Limits: Unblinded trial; filter usage showed modest attrition over time, and some households lacked drinking water at visit times.
