One-third of the cases (164) stayed at a resort during their travel; salmonellosis was reported among 46.3% of them (76/164) (Table 3). No statistically significant differences existed between years and months for departure and return dates. Both travel departure and return dates were available for 351 cases. Overall, the travel duration ranged from 0 to 1,333 days with interquartile at 7 (Q1), 14 (median), and 30 days (Q3) (Table 3). Statistically significant differences in travel durations were found between the diseases. DNA Damage inhibitor Travel duration was short for salmonellosis, VTEC infection, and yersiniosis (median duration: 5–8 d); medium for amebiasis, Campylobacter enteritis, cryptosporidiosis,

and shigellosis (median duration: 15–24 d); long for giardiasis and typhoid and paratyphoid fever (median duration: 30–39 d); and very long for hepatitis A (median duration: 102 d). MCA click here allowed us to map out a large portion of the variability in the data for the 351 cases with no missing data on the first two-dimensional plan, the first and second axis encompassing 73 and 11% of the total inertia, respectively (Figure 2a). Travel destination, travel duration, and accommodation in a resort were the three variables that contributed most to the first axis, with the categories Latin America/Caribbean, short travel (<8 d), and accommodation in a resort pointing in the opposite direction compared

to the categories Asia, Africa, and long travel (29+ d) (Figure 2a). The categories Europe, <5 and 60+ years contributed the most to the second axis, these two age groups pointing in opposite directions. Accounting for gender did not change the results and consequently this variable was ignored. These results allowed us to define three potential subgroups among ill travelers by the combination of the various categories that make up the variables analyzed: those who had traveled to Latin America/Caribbean for a short period (<8 d) and had stayed at a resort (subgroup A); those who had traveled to either Asia or Africa for a long period of time (29+ d) (subgroup B); and travelers aged

60 years or older who had traveled to Europe (subgroup C). These subgroups encompassed 84, 79, and 12 find more cases, respectively. When illness was overlaid on the MCA map it showed associations between these subgroups and the diseases (Figure 2b). In particular, cyclosporiasis, salmonellosis, and yersiniosis were most frequently identified within subgroup A; hepatitis A and typhoid and paratyphoid fever within subgroup B; and Campylobacter enteritis within subgroup C (Table 4). Illness among the 42 TRC classified as new immigrant were giardiasis (27 cases), amebiasis (12 cases), Campylobacter enteritis (2 cases), and typhoid fever (1 case). They were not included in the MCA because of missing departure date. Overall, TRC accounted for 25.
