Throughout the world, people are needlessly suffering from an easily preventable disease called Guinea worm. When this disease occurs, a worm literally grows inside of a personís body. Symptoms of the disease include: fever, severe pain and swelling, and a burning blister. Guinea worm is caused by drinking water containing water fleas that are infected with larvae. Once ingested, the larvae become female worms and migrate towards the surface of the skin, where the blister forms. Often the blister forms near the foot.The blister eventually breaks, and the worm must be pulled out of the body. Since a worm could be up to 1 meter long, the process could take months to complete. Guinea worm disease occurs annually in poor areas when the agricultural production is at its highest. Many times the disease affects workers who are vital to production,so it hampers agricultural production and weakens to economy.
