AB Trichuriasis  is  caused  by  infection  of  the  large  intestine  with  Trichuris  trichiura,  the  whipworm.  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.
