"Researchers at Columbia University say that a child who lives 250 meters from another child who has been diagnosed with autism has a 42 percent increased chance of being diagnosed himself or herself. Children who live between 250 and 500 meters of another child diagnosed with autism have a 22 percent increased chance of being diagnosed themselves. The researchers based this conclusion on a study of more than 300,000 children in California between 1997 and 2003. Children who live further away from another child diagnosed with autism have a lower risk of being diagnosed themselves."
