Dracunculus medinensis or Guinea worm is a nematode that causes dracunculiasis, also known as guinea worm disease.[1] The disease is caused by the female[2] which, at up to 800 mm (31 in) in length,[3] is among the longest nematodes infecting humans.[4] In contrast, the longest recorded male Guinea worm is only 40 mm (1.6 in).[3]

Eradication programme[edit]

In the 1980s a programme to eradicate guinea worm was begun, including by the Carter Center. The programme included education of people in affected areas that the disease was caused by larvae in drinking water, isolation and support for sufferers, and – crucially – widespread distribution of net filters and pipe filters for drinking water, and education about the importance of using them.

As of 2015 the species has been reported to be near eradication. [5]
