Roundworms can also cause a condition called visceral larva migrans in which immature worms move through a person's body, causing fever, an enlarged liver, anemia or pneumonia. (vetinfo.com)
In people, hookworms can cause intestinal problems or a condition called cutaneous larval migrans in which the worms leave itchy, red trails in the skin as they move under it. (vetinfo.com)
After larvae are finished with their migration or gotten lost in the process, symptoms usually subside in a few weeks but human death has occurred from visceral larva migrans in severe cases. (vin.com)
