9 A number of factors—including foreign birth, traveling alone, traveling for less than 14 days, and traveling for vacation—independently predicted a lower likelihood of pursuing health information prior to departure. Most commonly, travelers reported a lack of concern about health issues as the primary reason that they did not pursue health information prior to their trip. These findings underscore that efforts are needed to heighten the awareness of the risk associated with travel to LLMI countries. Among travelers to LLMI countries who sought health advice prior to departure, we found the internet to be the most common source of information.

However, only a small proportion (11%) of all travelers to LLMI countries visited the CDC Travelers’ Health website. Primary care practitioners Selleck Ceritinib were another common source of health information among travelers to LLMI countries, and VFR travelers were particularly likely to have pursued health information from a primary care practitioner. Less than a third of travelers to LLMI countries who pursued health information visited a travel medicine 5-FU nmr specialist, and among VFR travelers,

this number was only 3%. Boston Logan International Airport is one of the United States’ largest airports in terms of passenger volume and flight movements,10 and travelers departing from Boston Logan International Airport are likely similar to those departing from other major hubs in the United States. Nevertheless, an important limitation of our study was its restriction to a single US airport. Due to the travel patterns from Boston Logan International Phloretin Airport, few survey respondents were directly traveling to Southeast Asia or sub-Saharan Africa. Furthermore, although our survey was conducted over more than 7 months, the sample size for any given destination was small and precluded any analysis

by geographic destination or country of birth. Survey data from other points of departure in the United States would be useful for gathering information on a broader range of travelers and for identifying any characteristics unique to travelers to specific destinations. Our results suggest a number of interventions that might be productive in improving the health knowledge of travelers to LLMI countries. In particular, we found the internet to be a key source of health information for travelers to LLMI countries. Given this finding, focusing education interventions at the time of online ticket purchase or through popular websites for travelers might be productive. Linking directly from such sites to the CDC Travelers’ Health website may be a useful tactic, as many survey respondents did not use this resource. Providing web-based material in languages other than English may be useful for targeting foreign-born travelers.
