    ntroduction : Dracunculiasis is infection with Dracunculus medinensis, a nematode worm. It is caused by drinking water containing water fleas (Cyclops species) that have ingested Dracunculus larvae. In the human body, the larvae are released and migrate through the intestinal wall into body tissues, where they develop into adult worms. The female worms move through the person’s subcutaneous tissue, causing intense pain, and eventually emerge through the skin, usually at the feet, producing oedema, a blister and eventually an ulcer, accompanied by fever, nausea, and vomiting. If they come into contact with water as they are emerging, the female worms discharge their larvae, setting in motion a new life cycle. There are no drugs available for the treatment of this disease. However, it can be prevented by protecting water sources and filtering potentially contaminated water. There is no vaccine or medicine to treat or prevent Guinea worm disease. Once a Guinea worm begins emerging, the first step is to do a controlled submersion of the affected area in a bucket of water. This causes the worm to discharge many of its larva, making it less infectious. The water is then discarded on the ground far away from any water source. Submersion results in subjective relief of the burning sensation and makes subsequent extraction of the worm easier. To extract the worm, a person must wrap the live worm around a piece of gauze or a stick. The process can be long, taking anywhere from hours to a week. Gently massaging the area around the blister can help loosen the worm Pathophysiology : Dracunculiasis is caused by drinking water containing water fleas (Cyclops species) that have ingested Dracunculus larvae. The acidic environment of the stomach and duodenum kills the copepods. The larvae are subsequently released in the stomach or small intestine and penetrate the mucosa to mate and mature in the abdomen or retroperitoneal space approximately 60-90 days after initial infection. The maturation stage can last for up to 1 year, and, during this time, the adult male probably dies because only the female worm is recovered from symptomatic patients. After maturation is complete, the female Dracunculus reaches a length of up to 1 m (with a thickness of only 1-2 mm) and slowly migrates from the GI tract into subcutaneous tissue, usually to a location in the lower extremity. The female worms move through the person's subcutaneous tissue, causing intense pain, and eventually emerge through the skin, usually at the feet, producing edema, a blister and eventually an ulcer, accompanied by fever, nausea, and vomiting. If they come into contact with water as they are emerging, the female worms discharge their larvae, setting in motion a new life cycle. Free-living larvae can survive only 3 days without a host; they become infective after 2 weeks (2 molts) within the host copepod.
