Dracunculiasis is caused by a nematode parasite Dracunculus medinensis, also known as Guinea worm. This disease was wide spread in Asia and Africa with approximately 3.6 million affected people in 1986 as reported by the Carter center. This disease is devastating that it incapacitates people affected by this worm although there is no permanent damage. Thanks to efforts of various governments and non profits like The Carter center the disease incidence reduced to 22 cases in 2015.
NPR radio today reports that further only 2 confirmed cases in 2016. This is a great progress comparable with eradication efforts of small pox and polio.
