Definition
Whipworm infection is an infection of the large intestine with a type of roundworm.
Overview, Causes, & Risk Factors
Whipworm infection is caused by the roundworm, Trichocephalus trichiura. It is a common infection that mainly affects children.
Children may become infected if they swallow soil contaminated with whipworm eggs. When the eggs hatch inside the body, the whipworm sticks inside the wall of the large intestine.
Whipworm is found throughout the world, especially in countries with warm, humid climates. The main risk factor for infection is swallowing soil contaminated with feces. Some outbreaks have been traced to contaminated vegetables (believed to be due to soil contamination).
