Signs and Symptoms of Guineworm

A few days to hours before the worm emerges, the person might develop a fever and have swelling and pain in the area where the worm is. A blister develops and then opens into a wound. When the wound is immersed in water, the worm begins to emerge. Most worm appears on the legs and feet, but they can occur anywhere on the body. After the worm emerges, the wound often becomes painfully swollen and infected.
