Overview
The nematode (roundworm) Trichuris trichiura, also called the human whipworm causes infection.
Causes
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. Some outbreaks have been traced to contaminated vegetables (believed to be due to soil contamination).
Epidemiology and Demographics
Whipworm infection is the third most common round worm of humans. Worldwide, infections are more frequent in areas with tropical weather and poor sanitation practices, and among children. It is estimated that 800 million people are infected worldwide. Trichuriasis occurs in the southern United States.
Infections with the soil-transmitted intestinal helminths (i.e., Ascaris lumbricoides, Trichuris trichiura, and hookworm), estimated to affect approximately 1 billion persons, are among the most common and widespread human infections.
Treatment
Medical Therapy
Mebendazole taken by mouth for 3 days is commonly prescribed when the infection causes symptoms. Albendazole is used as an alternative therapy. Full recovery is expected with treatment.
Primary Prevention
Improved facilities for feces disposal have decreased the incidence of whipworm. Always wash your hands before handling food. Thoroughly washing food may also help prevent this condition.
