Tunga penetrans, commonly known as the chigoe flea or jigger, is a parasitic insect found primarily in tropical regions of Africa and South America. It is a small, wingless flea that burrows into the skin of its host, often in the feet, causing irritation and potential infections. The female flea embeds itself in the skin to lay eggs, leading to painful lesions. In addition to causing discomfort, Tunga penetrans can lead to secondary infections if not treated properly. Prevention includes wearing shoes in endemic areas and maintaining good foot hygiene. Treatment typically involves the removal of the flea and proper wound care.
