Cutaneous larva migrans (CLM) is a clinical diagnosis based on the presence of the characteristic signs and symptoms, and exposure history to zoonotic hookworm. For example, the diagnosis can be made based on finding red, raised tracks in the skin that are very itchy. This is usually found on the feet or lower part of the legs on persons who have recently traveled to tropical areas and spent time at the beach. There is no blood test for zoonotic hookworm infection. Persons who think they have CLM should consult their health care provider for accurate diagnosis.
