Hookworms are zoonotic, meaning they can infect humans. Cutaneous larval migrans is caused by hookworm larvae that penetrate the skin of people who come into contact with moist soil harboring the hookworm larvae. In humans, the parasites usually die in the skin leaving a reaction of redness, irritation, and itching. Prevention includes annual stool testing/deworming of pets, wearing shoes outside, and wearing gloves when gardening. Consult your veterinarian and physician for more information.
