Cutaneous Larva Migrans, "Creeping Eruption", is a parasitic infection by the hookworms: Strongyloides, Ancylostoma, and Necator. These hookworms are usually present in moist soil. Spread is therefore through unprotected contact with moist soil or sand harboring the hookworms and there eggs. The lesions are red, itchy, and corsing-like/winding in nature ("serpiginous thread-like lesions"). This pattern is because of the growth and movement of the nematode larvae within the skin. Affects the hands, feet and buttocks.
