What is it?
Pinworms are small, white, thread-like worms that reside in the rectum.
Signs and Symptoms
- At night, the worms move from the anus (bum) to lay eggs on nearby skin.
- Although uncomfortable, pinworms do not cause disease.
- Children may experience itching around the anus and vagina, particularly at night, which can lead to sleep disturbances and irritability.
- Treatment involves special medication prescribed by a doctor.
How does it spread?
- Pinworms are common in children and can spread easily, especially in childcare settings.
- Direct spread occurs when an infected person transfers eggs from their fingers or under their nails, to another person's mouth.
- Indirect spread happens when eggs on objects like toys, toilet seats, clothing, or bedding are touched and then transferred to the mouth.
- Eggs can survive for up to two – three weeks outside the body, including on clothing, bedding or other objects
How to decrease spread
- Pinworms may come back if eggs are ingested again; they can survive in the home for up to two to three weeks.
- It's important for everyone to wash hands thoroughly after using the toilet, changing diapers, and before handling food.
- Wash bed linens and clothes without shaking them to avoid scattering eggs.
- Keep fingernails short and discourage nail-biting.
- Open blinds and curtains during the day as the eggs are sensitive to light
