Schizophrenia has long been blamed on bad genes or even bad parents. Wrong, says a growing group of psychiatrists. The real culprit, they claim, is a virus that lives entwined in every person's DNA.

Steven and David Elmore were born identical twins, but their first days in this world could not have been more different. David came home from the hospital after a week. Steven, born four minutes later, stayed behind in the ICU. For a month he hovered near death in an incubator, wracked with fever from what doctors called a dangerous viral infection. Even after Steven recovered, he lagged behind his twin. He lay awake but rarely cried. When his mother smiled at him, he stared back with blank eyes rather than mirroring her smiles as David did. And for several years after the boys began walking, it was Steven who often lost his balance, falling against tables or smashing his lip.
Those early differences might have faded into distant memory, but they gained new significance in light of the twins’ subsequent lives. By the time Steven entered grade school, it appeared that he had hit his stride. The twins seemed to have equalized into the genetic carbon copies that they were: They wore the same shoulder-length, sandy-blond hair. They were both B+ students. They played basketball with the same friends. Steven Elmore had seemingly overcome his rough start. But then, at the age of 17, he began hearing voices.
