(HealthScoutNews) -- Roundworms, a parasite (Toxocara) commonly found in the intestines of dogs and cats, can be passed from pets to humans and cause an infectious disease called toxocariasis. It sickens some 10,000 people yearly in the United States. More than 700 of them experience total or partial loss of vision.
Heavy or repeated Toxocara infections, while rare, can initiate a disease that causes swelling of the body's organs or central nervous system.
