Guidance for Cargo Ships: How to Report Onboard Death or Illness to CDC

According to federal regulations, CDC requires the master of a ship destined for a U.S. port to report immediately any death or certain illnesses among the ship’s passengers or crew. Effective on March 21, 2017, the definition of ill person under CDC regulations changed. This change, found in 42 Code of Federal Regulations part 71.1, clarifies the list of signs and symptoms that may indicate a person is ill with a communicable disease of public health concern. There is no change to the methods for reporting these illnesses or deaths to CDC. To report an illness or death onboard, use the Maritime Conveyance Illness or Death Investigation Form pdf icon[PDF – 4 pages] (Updated as of 11/10/2021).

The only exception is reporting Legionnaires’ disease. To report a case of Legionnaires’ disease, please e-mail For more information about Legionnaires’ disease, visit CDC Respiratory Diseases Branch (RDB).

This includes names, addresses, phone numbers, dates (birth, hospital admission, travel), identifying numbers (passport, social security, driver’s license, alien), medical records, photographs, and for rare diseases, geographic locations.
