Dracunculiasis, commonly known as Guinea worm disease (GWD), is induced by the parasite Dracunculus medinensis. GWD is transmitted by water containing larvae of the Guinea worm. GWD impacts poor populations in rural areas of Africa that lack access to potable water. GWD may happen at any time of year, although it is more widespread during the peak transmission period, which varies by country.
Dracunculiasis predominantly affects humans. However, infections in animals, notably dogs, have been observed in recent years. As a consequence of studies into the source of Guinea worm infections in animals, it is currently believed that GWD might be transferred to both humans and animals via the ingestion of some aquatic creatures, such as fish and frogs, which may contain Guinea worm larvae but are immune to transmission. Dracunculiasis is the first parasitic ailment to be targeted for extinction, and is considered a neglected tropical disease (NTD) by global health officials.
