Whipworm infection is cosmopolitan, but it is far more common in warm, moist climates, where the distribution of Trichuris and Ascaris overlap.1,2 Approximately 604 million people are infected worldwide. Infection is generally acquired in childhood; whipworm ova often pollute the ground where children play. Transmission of infection occurs by ingesting embryonated eggs, which may contaminate hands or food, including fruits and vegetables, that were fertilized using human feces.3 The lifecycle is shown in eFig. 333.1.
