  • After changing a diaper
• When camping:
  • Bring bottled water for drinking, cooking, and brushing teeth.
  • Purify untreated water before using-boil, filter, or otherwise sterilize.
• Thoroughly wash or peel raw fruits and vegetables before eating.
• When traveling overseas:
  • Use only bottled water for drinking, cooking, or brushing teeth.
  • Only eat food that is adequately cooked and served steaming hot.

• Keep swimming pools adequately chlorinated.
• Stay home from work and keep children home from school or daycare until the infection is gone.
