You or your child can get threadworms by accidently swallowing worm eggs found on contaminated surfaces. This can happen by scratching the anal region and then touching your mouth or food.

Where do Threadworms come from?

Causes of threadworms

A threadworm infection is passed from person to person by swallowing threadworm eggs. A female threadworm can lay thousands of tiny eggs around the anus or vagina. The female threadworm also releases mucus, which can cause an itchy bottom.

Do Threadworms go away on their own?

Threadworms do not go away by themselves, and people do not build up immunity to them, so they must be treated in order to eradicate them totally from the body.
