Filariasis (or philariasis) is a parasitic disease caused by an infection with roundworms of the Filarioidea type.These are spread by blood-feeding black flies and mosquitoes. This disease belongs to the group of diseases called helminthiasis.Eight known filarial nematodes use humans as their definitive hosts.
