5 Comparisons of certain characteristics between VFRs and non-VFRs are shown in Table 2. VFRs represent the largest category of travelers for each of the three diseases. Among VFRs, 40% of cases were under 20 years of age, compared to less than 6% among non-VFRs (p < 0.000). In Canada, only 11% of VFRs were under 20 years of age in 2008,5 but in our study, this age group accounted for 16.9% of malaria cases, 50% of typhoid cases, and 65.2% of hepatitis A cases among VFRs.

The median age of cases among VFRs is 32 years for malaria (vs 37.5 y among non-VFRs), 19.5 years for typhoid fever (vs 34.5 y), and 15.5 years for hepatitis A (vs 37 y). As for trip duration, 73% of cases among VFRs had traveled for 30 days or more, compared Selleckchem Dabrafenib to 51.8% of non-VFRs (p < 0.000). No case among VFRs was reported with a trip of 1 week or less. However, it is worrisome to note that a ubiquitin-Proteasome system fair proportion of cases among VFRs occurred following a trip of intermediate length, ie, from 15 to 29 days, which is almost 30% of the malaria cases and 21.2% of the typhoid cases. The proportion of hepatitis A cases reported following a trip of 14 days or less is clearly higher among non-VFRs

(61.7%) compared to VFRs (1.6%). The highest proportion of cases among VFRs occurred in the 3rd quarter, between July 1 and September 30: 31.3% of malaria cases, 41.2% of typhoid cases, and 56.1% of hepatitis A cases (Table 3). This seasonal variation in cases among VFRs differs significantly (p = 0.004) from non-VFRs. In terms of gender, no statistically significant difference

was found between VFR and non-VFR cases. Pre-travel consultation data is to be interpreted with care due to lack of information in most cases (222/309), and even when it is available, we cannot rule out social desirability bias in the answer. Table 4 shows the main regions of acquisition reported for the three diseases under study, for VFRs and non-VFRs. Among VFRs, 79.8% of cases traveled to Africa or the Indian subcontinent, compared to 49.2% of cases among non-VFRs. Virtually all (91.6%) of the malaria cases among VFRs were acquired in Africa, particularly in sub-Saharan Africa. The Plasmodium falciparum type accounts for 86.4% of malaria cases among VFRs. The vast majority (76.6%) of typhoid fever cases among VFRs were reported by travelers Vildagliptin who had visited the Indian subcontinent. For hepatitis A, over 60% of cases among VFRs were acquired in Africa (including 31.9% in North Africa) or the Indian subcontinent. For non-VFRs, 60% of cases contracted hepatitis A while visiting so-called sunshine destinations favored by Quebecers, namely Cuba, Mexico, and the Dominican Republic. Data were compared with Provost et al.7 and De Serres et al.19 studies. Since 2000 to 2002, the proportion of malaria cases attributed to VFRs more than doubled (52.9% vs 25%), and for typhoid, it increased to 94.4% from 86%.
