None of the travelers had symptoms suggesting mountain sickness

None of the travelers had symptoms suggesting mountain sickness. This is in agreement with the study of Cooper et al. which suggested that healthy elderly travelers can easily tolerate stays at moderate altitudes.18 Multivariate analysis demonstrated that only travel to East Asia (OR 4.66) and backpacking (OR 1.94) were associated with illness. The fact that backpacking mode of travel and not age or eating and drinking habits was associated with illness might suggest that the environmental

health hazards, both those associated with the destination and those associated with personal exposure, affect the health of the traveler. The environmental factors are probably more complex, extending beyond food and drink hygiene. These might include variables such as efficient sewage systems in the boarding facility, crowding, personal hygiene, selleck screening library and parasite infestations. Interestingly, illness in our study was associated with traveling to East Asia, while visiting India was not associated with an increased risk of illness. While 38% of the travelers visiting Thailand reported an illness, only 24% of those visiting India did so. This is in contrast to studies by Rack et al. and Greenwood et al. that found visiting India to be an increased risk.9,19 A possible explanation

for our finding might be that Thailand has become an increasingly PARP inhibitor popular destination in recent years among Israeli travelers of all ages. Its perception as a developing country has been consistently eroded,

a process that has been accompanied by an increasing disregard for the recommended dietary restrictions by Israeli tourists. India, on the other hand, is still perceived as carrying high health risks. Another possible explanation is that our cohort of short-term travelers differs substantially from the cohorts included in the GeoSentinel study. The majority of our cohort of travelers to India were adults who traveled in organized tours for less than a month, and not backpackers traveling for several months, who constitute many of the GeoSentinel study participants. Elderly travelers were significantly more compliant with anti-malarial medications prescribed as chemoprophylaxis than younger travelers (61% vs 34%, respectively). This is in accordance with the rates reported in other surveys Epothilone B (EPO906, Patupilone) of European, North American, and Israeli travelers.2,9,13,20 Many travelers, especially younger ones, fear the potential side effects of anti-malarial drugs, particularly neuropsychiatric problems associated with mefloquine. This was stated as a reason for not taking these medications by 29% of the younger travelers compared to only 7% of elderly travelers who did not take chemoprophylaxis as recommended. Perhaps as a compensatory measure, significantly more of the younger travelers used mosquito repellants (60% vs 47%) for protection.
