The human whipworm (Trichuris trichiura or Trichocephalus trichiuris) is a roundworm, which causes trichuriasis when it infects a human large intestine. The name whipworm refers to the shape of the worm; they look like whips with wider “handles” at the posterior end. The long ‘lash’ of the whip burrows into the cells lining the intestine, thus creating a particularly intimate relationship between parasite and host …

There is a worldwide distribution of Trichuris trichiura, with an estimated 1 billion human infections. However, it is chiefly tropical, especially in Asia and, to a lesser degree, in Africa and South America. Poor hygiene is associated with trichuriasis as well as the consumption of shaded moist soil, or food that may have been fecally contaminated. Children are especially vulnerable to infection due to their high exposure risk.
