Toxocariasis, is caused by migration of larval forms of a type of parasitic round worm which is part of the Toxocara species. Toxocariasis is a chronic, usually mild disease. Toxocariasis is common wherever dogs are found and the larval eggs can survive in the environment. Children are more commonly affected than adults, with disease rates found to be highest in children under six years of age.
