A nematode worm (Dracunculus medinensis) that is a parasite of humans in tropical Africa and formerly in Asia. Larvae are transmitted to humans when infected copepods are ingested in drinking water.

guinea worm

A nematode worm (Dracunculus medinensis) that is a parasite affecting subcutaneous tissues of humans and animals, found in tropical Africa and South Asia. The worm causes infection when its larvae are drunk in unfiltered or unsanitary water. The larvae enter the body through the stomach or duodenum, migrate through internal organs, and become adults. After mating, the adult female burrows to the subcutaneous tissue, often of the leg. The worm has been eradicated in Asia. See: Medina worm

Guinea worm

The parasitic worm Dracunculus medinensis . This occurs in many areas of tropical Africa and America. The worm is acquired by drinking water containing Cyclops water fleas that have ingested the worm larvae. The adult female worm, about 1 m long, settles under the skin and breaks through to release larvae, especially when the skin is in contact with water. She can be removed by winding her carefully out on a twig.
