Overview | Symptoms | Treatment | Prevention

Alternative names:

Trichuriasis

Definition:

This parasitic infection of the large intestine is caused by whipworm (Trichocephalus trichiura).

Causes and Risks

Whipworm infection is a common worldwide infection affecting primarily children, which may develop upon ingestion of soil contaminated with whipworm eggs. The ingested eggs hatch, and the whipworm embeds in the wall of the large intestine (cecum, colon, rectum).

Whipworm is found throughout the world, in particular among countries with warm, humid climates. The main risk factor for infection includes ingestion of eggs from soil contaminated with feces. Some outbreaks have been traced to contaminated vegetables (due to presumed soil contamination).

The development of symptoms depends on the burden of worms/eggs. Light infestations may lead to few or no symptoms. Heavy infestations may result in bloody diarrhea, iron-deficiency anemia, and on occasion, rectal prolapse.
