The Chigoe flea, also known as the jigger flea or Tunga penetrans, is a small parasitic insect found primarily in tropical regions of Africa and South America. It is notable for its ability to burrow into the skin of its host, often in the feet, causing irritation and potential infections. The female flea lays eggs under the skin, leading to further complications if not treated. Chigoe fleas thrive in sandy environments, such as those found in rural areas. They are often associated with poor sanitation and living conditions. Prevention includes wearing shoes and maintaining good hygiene to reduce the risk of infestation.
