    ### Instruction:
    How to prevent Parasites - Toxocariasis (also known as Roundworm Infection) ?
    ### Response:
    Controlling Toxocara infection in dogs and cats will reduce the number of infectious eggs in the environment and reduce the risk of infection for people. Have your veterinarian treat your dogs and cats, especially young animals, regularly for worms. This is especially important if your pets spend time outdoors and may become infected again.
