Important Reporting Reminders Acute Respiratory Illness (ARI) Reporting and Management This Maritime Conveyance Cumulative Acute Respiratory Illness (ARI) Reporting Form will be used to conduct surveillance on board cruise ships using cumulative reports of acute respiratory illness (ARI), which includes illnesses that meet the syndromic case definition below, including those for which testing has not been conducted; those with negative test results for COVID-19, influenza, or respiratory syncytial virus (RSV); and confirmed COVID-19 [3], influenza, and RSV infections. Cruise operators should be familiar with CDC’s Guidance for Cruise Ships on Acute Viral Respiratory Illness Management, including its testing and isolation recommendations. Individual non-fatal cases of COVID-19, influenza, RSV, or unspecified ARI do not need to be reported to CDC quarantine stations using the Maritime Illness and Death Investigation form. Reporting Cruise Ship Fatalities or Other Illnesses of Public Health Concern Fatalities and all other illnesses of public health concern (e.g., tuberculosis, varicella, measles, pertussis) should be reported via the Maritime Conveyance Illness or Death Investigation Form to the appropriate CDC Quarantine Station. Acute gastroenteritis or diarrhea: should be reported to CDC’s Vessel Sanitation Program (VSP) via the Maritime Illness Database and Reporting System (MIDRS). For more information, visit CDC Vessel Sanitation Program (VSP) Legionnaires’ disease: should be reported to CDC’s Respiratory Diseases Branch at [email protected]. For more information about Legionnaires’ disease, visit CDC’s Respiratory Diseases Branch (RDB).
