WHITFIELD: Doctors are looking for clues to a mysterious new disease that produces AIDS-like symptoms, even though it has no link to HIV. Researchers say the disease causes patients to make antibodies that attack their immune system. It makes them vulnerable to opportunistic infections like pneumonia. More than 100 cases have surfaced in East Asia. 12 people have been diagnosed in the U.S., all are of Asian descent. The disease is not contagious. CNN has learned that three U.S. Marines were injured in a shooting south of Mexico City taking place earlier this morning. The servicemen were on a diplomatic mission, we understand. It's still unclear what the motive to that shooting or attack may have been. We'll keep you posted as we get more information.
