additional insurance for sports or adventure coverage is the single most important concept. In addition, health care provid- ers should be aware of the special medical problems that can arise in the growing area of extreme travel.
Demographics
Although there are no comprehensive demographic data
characterizing this group of travelers, there are some relevant data that can be extrapolated to obtain a profile of extreme trav- elers. Among studies of backpackers to wilderness and interna- tional destinations, the average age of 32 years is younger than that of United States international travelers as a whole, which is 44 years. Illness rates among general international travelers between the ages of 20 and 40 years are almost double that of older international travelers.
General Risks
In reviewing a topic such as extreme travel, the goal is not to
provide an all-encompassing tome giving advice for every pos- sible exotic destination and all manner of extreme recreational activity. Instead, there are common generalizable risks for ex- treme travelers as a group that health care providers should be- come familiar with. Principal among theses risks is longer dura- tion and more remote travel. Common factors in this cohort that have been independently associated with either not seeking or noncompliance of pre-travel advice are: younger age, longer duration of travel, and individual travel. The highest single risk is trauma related to local transportation or the activity itself. Statis- tically, local transportation in a developing country in rural areas is the highest risk for all travelers. Tourists driving themselves have a 6-fold higher likelihood of a motor vehicle collision than a local citizen, with an additional 2.5-fold higher risk if driving E xtreme travel is defined as journeying to remote destina- tions or participating in unusual high-risk activities during tYPical traVel iNsUraNce exclUsioNs

Pre-travel advice should consist of more than the recommend-

Adventure travel is primarily a North American, Western European, and Australian hegemony; however, this will presum- ably change in the coming decade with increasing diversity of travel originations and destinations.
