Toxocariasis is the parasitic disease caused by the larvae of two species of Toxocara roundworms: Toxocara canis from dogs and, less commonly, Toxocara cati from cats. Toxocariasis is considered one of the Neglected Parasitic Infections, a group of five parasitic diseases that have been targeted by CDC for public health action.
