In the human body, the larvae can penetrate deeper layers of the skin (dermis) that infect the bloodstream and into the lymphatic system When the larvae stay in the gut, they mature and lay their eggs, which are then excreted to start a new cycle However, in the human body, the larvae cannot penetrate through the basement membrane to enter the dermis, so the disease is limited to the outer layer called the epidermis.
