7 However, very little information is available regarding the risk behaviors and the health of elderly travelers, before, during, and after travel, compared to their younger counterparts. Due to their more complex medical background and decreasing immunity we hypothesized that elderly travelers would be more prone to various health risks and would seek medical care more intensively during and after travel. The objective of this study was NVP-LDE225 purchase to assess the risk factors for

travel-related diseases and their occurrence in a population of elderly (aged 60 years and older) Israelis traveling to developing countries compared to young Israeli travelers (aged 20–30 years). Our travel clinic boasts about 6,500 visits per year and is open to travelers of all ages. Travel clinic visits are covered by all health insurances; thus, attending the clinic Stem Cells antagonist requires a modest self-payment only. Inclusion criteria were individuals aged 20 to 30 years or 60 years and older who attended the Meir Medical Center Traveler’s Clinic from January to June 2008. Since the majority of the elderly travel for less than a month, to avoid heterogeneity, only people traveling within

this time frame were included. Prior to travel, each person received detailed counseling and written information regarding travel-associated health risks, including malaria, traveler’s diarrhea, and mountain sickness according to professional guidelines.8 Counseling to all travelers was performed by a staff of three infectious diseases physicians, and included a filmed presentation followed by personal counseling done according to a standardized form. All travelers were immunized

against vaccine-preventable illnesses according to current recommendations8 and provided with prescriptions for prophylactic anti-malarial medications as needed CHIR-99021 cost according to their itinerary. Six to 12 months after the pre-travel clinic visit (4 to 10 months after return), all travelers fitting the inclusion criteria were systematically approached by telephone. A maximum of four attempts were made, at different times of the day, to contact each traveler. Travelers who had been contacted were enrolled and interviewed by telephone using a standardized questionnaire. The questionnaire addressed demographics, underlying medical conditions, current prescription medications, travel history, and characteristics. Risk behaviors, preventive measures, and compliance with anti-malarial medications were assessed. Risk behaviors assessed included eating and drinking habits (purchasing food from street vendors, eating food that was not properly cooked, drinking tap water, open beverages or using ice) as well as non-compliance with malaria prophylaxis measures (using repellants and chemoprophylaxis) and mountain travel. Having bought food on the street, eating improperly cooked food, or drinking anything apart from canned/bottled beverages even once were considered risky behaviors.
