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. Symptoms include:

  • Light infestations are frequently asymptomatic.
  • Heavy infestations may have bloody diarrhea.
  • Long-standing blood loss may lead to iron-deficiency anemia.
  • Rectal prolapse is possible in severe cases.1
