Definition of Whipworm infection:

Whipworm infection is infection of the large intestine caused by Trichocephalus trichiura.

Causes, incidence, and risk factors:

Whipworm infection is a common worldwide 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 (due to presumed soil contamination).
