Abstract:
Objective:To observe the prevalence and the characteristics of infectious disease outbreak on international cruise ships from 2006 to 2020，and to explore relevant prevention and control measures.Methods:Sourced from the website of the Vessel Sanitation Program at the U.S. Centers for Disease Control and Prevention，the data of 223 cases that met the definition of infectious disease outbreaks on international cruise ship and took place between 2006 to 2020 were analyzed using epidemiological statistics methods.Results:From 2006 to 2020，the number of infectious disease outbreak on international cruise ships generally showed a downward trend，though with small fluctuations. Among the 192 outbreaks of infectious diseases with identified pathogens，181 outbreaks arose from viral infectious diseases（81.17%），10 from bacterial infectious diseases（4.48%），and 1 from other infectious diseases（0.45%）. Besides，there were another 31 outbreaks（13.90%）with unidentified causes or unavailable specimens. Norovirus，Enterotoxigenic Escherichia coli（ETEC），and Shigella and Salmonella were the main pathogens that gave rise to the outbreak of infectious diseases on international cruise ships. January to April was the peak time of infectious disease outbreak on international cruise ships，while other months kept a low incidence of such outbreak. The prevalence of common ship infectious diseases among crew members（2.01%）was lower than that of passengers（7.20%）.Conclusion:Infectious disease outbreak on cruise ships has its own characteristics and developing patterns. The main susceptible group to infectious diseases on cruise ships are passengers. The main routes of transmission are food and water．
