We use our hands to do many things every day. Our hands get dirty even when they look clean.
Dirty hands are the major cause of diarrhea and worms.
Everybody needs to wash their hands with soap and water regularly to protect themselves and others from diseases. KEEP your body clean by taking baths. KEEP your clothes clean. If that is not possible, bury the feces far from your home and your water source. WASH your hands after using the toilet.
