Tunga penetrans, commonly known as the chigoe flea or jigger, is a parasitic insect found primarily in tropical and subtropical regions. It is notable for its ability to burrow into the skin of mammals, including humans, where it can cause painful lesions. The female flea embeds itself in the skin to lay eggs, leading to potential infections and complications if not treated properly. These fleas are often associated with poor sanitation and living conditions, particularly in rural areas. Prevention includes wearing closed shoes and maintaining good hygiene practices. Treatment typically involves careful removal of the flea and proper wound care to prevent secondary infections.
