Dracunculiasis

(Medinawurm-, guinea worm disease; “Fiery Serpent”)

A Dracunculiasis is infection with Dracunculus medinensis. The symptoms consist of painful inflamed skin lesions that contain an adult worm, and a severe arthritis. The diagnosis is obtained by the inspection. The therapy consists of the careful, slow removal of the adult worm.

About 25 years ago the Dracunculiasis was in large parts of tropical Africa, endemic in Yemen, India and Pakistan. Today, interrupting the transmission due to the international efforts, the infection occurs mainly in a narrow belt of African countries. The Carter Center reported that there were only 542 cases in 2012; all occurred in 4 African countries: South Sudan, Chad, Mali and Ethiopia.

To a pathophysiology of human infection occurs by drinking water, the infected copepods (copepods, dt. Hüpfer Linge) contains. The larvae are released, penetrate the intestinal wall and mature within approximately 1 year to adult worms in the abdominal cavity. After mating, the male dies and the pregnant females migrate through subcutaneous connective tissue, usually to the distal lower extremities. The head end of the worm causes a indurated papule that ultimately ulcerated. Upon contact with water (eg. For example, when a person tries to strong discomfort to alleviate by dipping the limb concerned) a loop uterus prolapses through the skin and is movable freely larvae. Worms that do not reach the skin, die and are decomposed or calcify. Larvae are taken up by copepods. In most endemic areas, the transmission is seasonal heaped place, and every infectious episode lasts about 1 year. Life cycle of Dracunculiasis.
