# A worm, which may be parasitic or free-living (WHO 1992).

==Explanation==
The word “helminth” comes from the Greek word meaning “worm” and refers to all types
of worms, both free-living and parasitic. The major parasitic worms are classified primarily
in the phylum Nematoda (roundworms) and the phylum Platyhelminthes (flatworms
including trematodes). Helminth parasites infect a large number of people and animals
worldwide. For most helminths, drinking-water is not a significant route of transmission.
There are two exceptions: Dracunculus medinensis (guinea worm) and Fasciola spp. (F.
hepatica and F. gigantica) (liver flukes). Dracunculiasis and fascioliasis both require
intermediate hosts to complete their life cycles but are transmitted through drinking-water
by different mechanisms. Other helminthiases can be transmitted through water contact
(schistosomiasis) or are associated with the use of untreated wastewater in agriculture
(ascariasis, trichuriasis, hookworm infections and strongyloidiasis) but are not usually
transmitted through drinking-water (WHO 2004).
