Tackling threadworms.

Threadworms are common parasites. They live in the intestine and migrate to the anus, sometimes causing an itchy bottom. Children are often affected, especially the under 10s. Threadworms are not a serious health hazard and parents can be reassured that neither the worms nor the treatment are likely to lead to any harm. The whole household should be treated on the same day. Mebendazole is an effective treatment. Tell the family to keep their nails short and wash their hands and scrub their nails after using the toilet and before meals. These precautions will help prevent a recurrence. Wash underwear and night-wear daily to destroy the eggs. Wear pyjamas or pants at night to help prevent fingers scratching the anal area.
