Feces Disposal can reduce diarrheal diseases by 30% or more.
Hand washing can reduce diarrheal diseases by 40% or more.
Improving Quality of Water at POU can reduce diarrheal diseases by 30%-40%.
Why Hygiene? POU water treatment – 30-40% reduction (twice as effective as interventions at water source) Safe storage – at least 20% reduction Proper hand washing – 40% or more reduction Sanitation – 30% or more reduction with basic, low-cost systems
