Summarize the following:
The best way to prevent an infestation begins here. Your hands are the part of your body most likely to transfer the pinworm eggs so keeping them clean means those eggs go down the drain. Make sure you and your family wash hands before eating or handling food, after using the bathroom, and after changing a diaper. Use warm water with a mild soap and vigorous hand-washing for about 30 seconds. Think two cycles of "Happy Birthday" or the "ABC song." Wash your hands before, during, and after any and all activities with institutionalized friends/relatives, co-workers, etc. Keep your hands away from your mouth whenever you are in a school or institutional environment. Be sure to wash your hands after attending to children who are being treated for pinworms. Avoid biting your fingernails. Remember, this is a pinworm egg's favorite hiding place. If you've come into contact with them or scratched an itch where the pinworms are hiding (e.g. clothes, exposed skin), they'll be hiding under your nails. Be careful not to trim them too short as that can cause other health issues for you or your loved one's fingers. Always make sure to clean under the fingernails both when washing your hands and taking baths/showers. It should be a general practice to keep that area clean. Have children wear close-fitting sleepwear and underpants and mittens. This will make it harder for them to scratch at night and pick up the worms. Every family member should shower or bathe every morning and change undergarments daily (showering may be preferred to avoid contaminated bathwater). During treatment, shower at night and in the morning to remove eggs that have been laid during the night. Doing so increases the risk of contact with the pinworm eggs. In fact, to be better safe than sorry, wash EVERYTHING in hot water. Just be careful not to put that red sock in with the whites. When you handle the bedding, clothing, and towels of an infected person (or one you may suspect is infected), do so carefully. Avoid shaking the articles and wash infected articles (underwear, bed linen, sleepwear, and towels) separately from other washing. Keeps drapes/curtains/blinds open all day because pinworm eggs are sensitive to sunlight.

Summary:
Practice and teach proper handwashing techniques. Keep fingernails clean and trimmed short. Avoid scratching the skin around the anus area. Avoid eating in the bedroom. Use hot water and high heat in your dryer for all bedding, towels, and clothes you suspect or know have come into contact with those infected. Bathe your rooms with light.
