B80: Enterobiasis

You have been infected with pinworms.

The pinworms live as parasites in the human body. You get infected when you get the worm eggs in your mouth or inhale them. Pinworms hatch in the intestine and multiply there. The intestines are made up of the small intestine and the large intestine or colon. Most of the nutrients are absorbed in the small intestine. The large intestine (colon) is where water and salt are withdrawn from the stool. The last segment of the large intestine (colon) is the rectum. Stool then leaves the body through the anus.

The females lay the new eggs in the person’s anal area. They cause a nasty itching there. Scratching can cause the worm eggs to get back to the mouth via your hands. The worm eggs may also stick to bedding, clothing or objects and get onto your hands and into your mouth that way. In this way the worm eggs can be passed on to other people.

The pinworms can cause discomfort. You may have bad anal itching. You may also get stomach pain, diarrhea or constipation.
