A cruise ship is an epidemiologist's case study in concentrated risk. Thousands of people from dozens of countries share enclosed air systems, buffet lines, swimming pools, and high-touch surfaces for days or weeks — creating conditions for infectious disease transmission that are unlike any other travel environment. Norovirus, COVID-19, influenza, Legionella, measles, and gastrointestinal outbreaks have repeatedly disrupted the cruise industry, stranding passengers, generating international headlines, and exposing gaps in shipboard health infrastructure.
Dr. Paul Kilgore is a physician-epidemiologist, former CDC Epidemic Intelligence Service Officer, and infectious disease researcher who has spent 36 years investigating how diseases spread through populations — including in the confined, mobile, and multinational environments that define cruise travel. He has authored more than 150 peer-reviewed publications in infectious disease epidemiology, led COVID-19 vaccine clinical trials, and worked across approximately 30 countries studying disease transmission and prevention.
This session examines the unique epidemiology of cruise ship outbreaks: why ships are so vulnerable, how outbreaks are detected and investigated in a maritime environment, what the CDC's Vessel Sanitation Program actually monitors, how the cruise industry's response protocols have evolved since COVID-19, and what remains dangerously inadequate. Dr. Kilgore uses real-world outbreak case studies to show how epidemiological principles apply in a floating city — and what passengers, crew, and industry leaders need to understand about the risks they face.
Attendees leave with a clear understanding of cruise ship outbreak dynamics and the prevention strategies that actually reduce risk — for passengers, crew, and the organizations responsible for both.
