Visceral larva migrans is a condition in humans caused by the migratory larvae of certain liver, heart (causing myocarditis) and the CNS (causing dysfunction, seizures, and coma). A special variant is ocular larva migrans where usually T. canis larvae travel to the eye.

Only a few roundworm eggs are necessary to cause larva migrans in the human child or adult. However, visceral larva migrans seems to affect children aged 1–4 more often while ocular larva migrans more frequently affects children aged 7–8. Between 4.6% and 23% of U.S. children have been infected with the dog roundworm egg. This number is much higher in other parts of the world, such as Colombia, where up to 81% of children have been infected.[5]

Cutaneous larva migrans is a condition where nematodes such as Ancylostoma braziliense migrate to the skin.

A list of causative agents of larva migrans syndromes is not agreed upon and varies with the author.[6]
