Epidemiologic Notes and Reports Outbreak of Pneumonia Associated with a Cruise Ship, 1994

On July 15, 1994, the New Jersey State Department of Health notified CDC of six persons hospitalized with pneumonia. An investigation was initiated to determine the etiology and potential sources and modes of transmission of the illness. These persons traveled between New York City and Bermuda aboard the cruise ship Horizon (Celebrity Cruise Line, port of origin: New York City) from June 25 through July 2. Subsequent investigations have identified 16 additional persons with pneumonia who had traveled on the vessel since May 28, 1994. Initial laboratory tests indicate Legionella sp. infection (Legionnaires' disease) has been confirmed in four of the 22 patients; specimens for laboratory testing are being collected from the other patients.

Physicians evaluating persons who developed pneumonia within 2 weeks after travel aboard the Horizon are encouraged to report these cases immediately to CDC through local or state health departments. Updated information is available from CDC's Division of Bacterial and Mycotic Diseases, National Center for Infectious Diseases, telephone (404) 639-3057.
