Prevention

To prevent getting or spreading giardiasis:

• Maintain good personal hygiene.
• Wash hands several times a day, especially:
  • Before eating or preparing food
  • After a bowel movement
  • 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.
• Do not let children with diarrhea go into swimming pools.
• Keep swimming pools adequately chlorinated.
• Stay home from work and keep children home from school or daycare until the infection is gone.
