Summary: A prospective observational, descriptive, and cross-sectional study was conducted aboard a cruise ship with a capacity of 200–264 passengers and 140 crewmembers, sailing in remote areas such as the Arctic Ocean and the Antarctic Peninsula for 205 days with 6640 individuals, including 3698 passengers and 2942 crewmembers. With a prevalence of 43.7%, infectious pathologies accounted for the majority of common ailments on board; respiratory infections were the most prevalent (prevalence of 63.6%). Such infectious agents on board are transmitted by contaminated passengers prior to embarkation and infected crewmembers during pauses ashore. Despite sanitary measures on board, it is difficult to prevent the spread of viral infections due to the close and frequent interactions between passengers – this is especially true for crewmembers, who frequently share cabins with four other people and are therefore more susceptible to infection.
