About The Guinea Worm

Guinea-worm disease is caused by the parasitic worm "Dracunculus medinensis" or "Guinea-worm". This worm is the largest of the tissue parasite affecting humans. The adult female, which carries about 3 million "embryos" (babies), can measure 600 to 800 mm in length and 2 mm in diameter. The parasite migrates through the victim's subcutaneous tissues causing severe pain especially when it occurs in the joints. The worm eventually emerges from the feet in most of the cases, causing a blister and an ulcer accompanied by fever, nausea and vomiting.

Other Information

The Guinea Worm lives in contaminated water which people drink and that's how they get it. It reproduces when the person goes in the water to soothe the pain and releases thousands of larvae.

Interesting Facts

1. To soothe the burning pain, patients often immerse the infected area in water. The worm then releases thousands of larvae into the water, contaminating the water and bringing the infective cycle full circle.
2.During the transmission season, contaminated ponds can be treated with the larvicide temephos which kills the infective water fleas.
3.Guinea-worm disease is transmitted exclusively by drinking stagnant water contaminated with tiny water fleas that carry infective guinea-worm larvae.
