Guinea worm larvae. Light micrograph of three Guinea worms (Dracunculiasis medinensis). This nematode (roundworm) is a parasite of humans, who become infected by drinking water containing copepods infected with Guinea worm larva. Approximately one year after infection the adult worm emerges through a painful blister on the skin. After a global campaign to eradicate Guinea worm it is now only endemic to four African countries, down from 20 Asian and African countries in 1986.
