NEW YORK (AP) _ Legionnaires' disease has been confirmed as the cause of death for a passenger aboard the cruise ship Horizon, health officials said today.

The death was the only one attributed to Legionnaires' among passengers from the Celebrity Cruises ship, which has been linked to 11 confirmed and 25 suspected cases of the disease, the U.S. Centers for Disease Control and Prevention said today.

Pasquale Cantone, 68, of Long Island who had been on the ship's July 2 trip to Bermuda, died July 22 at Good Samaritan Hospital after experiencing symptoms of Legionnaires'.

Officials had been awaiting autopsy results before attributing his death to the disease, a rare form of pneumonia. A lab confirmed late Thursday that he was infected with the bacteria, said Kristine Smith, a spokeswoman for the state Health Department.

The ship, which was taken out of service July 20 and sanitized, is to carry several hundred passengers to Bermuda this weekend.
