1) Students at a school in India launched a "Personal Hygiene Mission" to address absenteeism and health issues caused by poor hygiene in their village. 2) They visited homes and the village leadership to understand the problems and gain support. They then trained students and sent them to educate the community about hygiene practices like handwashing and using boiled water. 3) Both students and the community worked together to clean public spaces and homes. Students organized meetings to discuss hygiene, and the village saw improved student attendance and hygiene practices as a result.
