Threadworms are spread through contact with infected feces. This can happen when someone touches something that has been contaminated with feces, such as a doorknob or a piece of clothing. Threadworms can also be spread through food or water that has been contaminated with feces.
Once inside the human body, threadworms travel to the intestine. They attach themselves to the walls of the intestine and feed on the food that the person eats. Threadworms can cause a number of symptoms, including:
* Itching around the anus
* Restlessness and irritability
* Difficulty sleeping
* Weight loss
* Diarrhea
* Nausea
* Vomiting
Threadworms can be treated with medication. The medication is usually taken in a single dose, and it is effective in killing the worms.
To prevent threadworm infection, it is important to:
* Wash your hands frequently with soap and water.
* Avoid touching your face or mouth with unwashed hands.
* Keep your fingernails short.
* Avoid contact with infected feces.
* Wash fruits and vegetables thoroughly before eating them.
* Drink only boiled or filtered water.
If you think you may have a threadworm infection, see your doctor.
