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 Űngers and Űnger nails, and can easily get
into the mouth by Űnger 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 Űnger sucking
• Wear pyjamas or underclothes in bed
• Each morning, wash your bottom thoroughly
• Use a separate towel for each person in the
• Change clothes regularly
• Wash and iron bed linen regularly
• Wash hands and nails well after using the
toilet and before meals.
