7. Further advice regarding worms
Threadworms (pinworms) produce large numbers of tiny eggs. They may be present in house
dust and can stick to clothing, carpets, towels and bed linen. They can also be picked up by
contact with someone who already has worms. Because the eggs are so small, it is very easy
for them to be swallowed. Then they pass into the bowel where they grow into worms. The
female lays her eggs at night around the bottom. It is this that causes the "itchy bottom" and
leads to scratching. The eggs are then transferred to the fingers and finger nails, and can easily
get into the mouth by finger sucking or nail biting. The life cycle of an adult worm can be as
long as six weeks.
To stop you and your family infecting others or re-infecting yourselves, follow the advice below
for at least 6 weeks:
• Keep nails short
• Discourage nail biting or finger sucking
• Wear pyjamas or underclothes in bed
• Each morning, wash your bottom thoroughly
• Use a separate towel for each person in the house
• Change clothes regularly
• Wash and iron bed linen regularly
• Wash hands and nails well after using the toilet and before meals.
