Prevention:

• Practice good hygiene. Washing your hands before eating or preparing meals helps prevent spread of infection.
• Avoid scratching the anal region.
• Avoid biting the fingernails.
• Keep fingernails short and clean.
• Wash all bedding and pajamas regularly.
• Be sure your child changes underwear daily.
• Frequently vacuum the play area.
• Despite these measures, it still may be quite difficult to avoid reinfecting yourself or spreading pinworms to others.
