Threadworms, also known as pinworms, are small, thin worms that live in the human intestine. They are the most common type of worm infection in the United States, and most commonly affect school-age children. Threadworms are spread through contact with contaminated objects, such as clothing, toys, bedding, and furniture, and through the hands.
Threadworms live in the human intestine, where they feed off of nutrients in the food we eat. They are very contagious and can be spread from person to person through direct contact with feces, contaminated objects, or through contact with the hands. For instance, if someone who is infected with threadworms scratches their anus, the eggs can transfer to their hands and spread to other people or objects.
The most common symptom of threadworm infection is itching or irritation around the anus, especially at night. Other symptoms include difficulty sleeping, restlessness, irritability, and loss of appetite. People with threadworm infections may also experience abdominal pain or tenderness, nausea, or diarrhea.
In order to diagnose a threadworm infection, a doctor may take a stool sample and examine it under a microscope for the presence of threadworms or their eggs. Treatment typically involves taking an over-the-counter medication that kills the worms. To prevent reinfection, it is important to practice good hygiene, including regular hand-washing, cleaning of contaminated surfaces, and washing of bedding and clothing.
