Not only are more people traveling; travelers are seeking more exotic and remote destinations. Travel from industrialized to developing regions has been increasing, with Asia and the Pacific, Africa, and the Middle East now emerging destinations. Figure 6-1 summarizes the monthly incidence of health problems during travel in developing countries. Studies continue to show that 50–75% of short-term travelers to the tropics or subtropics report some health impairment. Most of these health problems are minor: only 5% require medical attention, and 40% of travelers’ deaths that are not due to cardiovascular disease or preexisting illness.
