Ascariasis is an infection of the small intestine caused by the nematode Ascaris lumbricoides, a large roundworm. Ascariasis occurs with greatest frequency in tropical and subtropical regions, especially in areas with inadequate sanitation. Humans become infected on ingestion of food or water contaminated with embryonated eggs of the roundworm. The larvae hatch in the small intestine, which then penetrate the intestinal wall to enter the lymphatics and venules. The larvae then migrate through various organs and finally reach back to the small intestine.
