Trichuris trichiura is the third most common nematode worldwide following Ascaris and Enterobius; in total, the three infections affect approximately 1 billion people. Whip worm infection is endemic in tropical and subtropical countries. The prevalence of Trichuris trichiura is high, affecting 95% of children in countries where protein energy malnutrition and anemia are prevalent.
