A child stays in class because her hands are clean: hygiene lessons reach 30 million children in 1 million schools

Across India, schoolchildren are learning handwashing as a daily habit they carry home to their families. The Dettol Banega Swasth India programme says it now reaches more than 30 million children in 1 million schools, with classroom walls and washing stations turned into learning aids, and reports that school absences linked to illness have fallen sharply where the lessons take hold. Teachers say the real change is simple: a child who stays healthy stays in class, and shows siblings at home what she learned.
