Pinworms lay eggs on the skin around the
anus.
Scratching the anus transfers eggs to the
hands.
A person becomes infected when they
transfer the pinworm eggs to their mouth.
An infected person can spread pinworms to
others by touching their food or other items.
The eggs fall onto clothing, bedding and the
floor. The eggs can live there for up to 3
weeks.
If you handle articles that have the eggs
attached, they can get onto your hands.
