B78.9: Strongyloidiasis, unspecified
The threadworms live as parasites in the human body. They penetrate the skin and move through the body to the intestine. There they reproduce. The threadworms can be excreted from the intestine or move on to other organs in the body. When the threadworms are excreted, the untreated stool can cause infections. As the threadworms can also survive in the ground, people in some regions can also get infected by walking barefoot.
The threadworms may infect the intestine, skin or other organs, for example. When the intestine is affected, you may have diarrhea and stomach pains. You may also be constipated or have blood in your stools. When the skin is affected, you may have an itchy rash.
