First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study in Lusaka, Zambia, tested whether giving households a handwashing bucket and supplies, along with hygiene education, increases handwashing with soap. 1,800 households with a child under 5 were split into four groups: hardware plus promotion, hardware only, promotion only, or no intervention. Researchers observed handwashing behavior to find the most effective approach.
