Accident hazards while traveling are generally treated far too lightly, although accidents are what most frequently put travelers in the hospital.
Studies from Switzerland and the United States prove that between 22-44% of fatalities in intercontinental travel are caused by accidents. Here, aircraft accidents at 2-4% are far less frequent than road accidents (7-13%). In any event, 4-9% of fatalities are caused by drowning and 11-12% from other injuries (falls while mountain climbing, etc.) Infectious diseases only figured in these studies with 1-3% of the fatality rate. The most frequent cause of fatality in all the studies was cardiovascular incidents, which stand at 14-49%. Road accidents were the most frequent reason for evacuation flights from tropical countries. Road conditions in tropical countries are often catastrophic, the vehicles old and in bad repair. Besides road conditions, staying in unfamiliar climates, especially high altitudes, is a significant risk factor. The death rate of trekkers in Nepal stands at 14 to 100,000 annually. Here, too, however, the primary cause of death is injury (37%), especially falls. In any case, 21% of these fatalities were caused by mountain sickness. So danger factors include ignorance of local hazards, alcohol consumption and a decreased awareness during the vacation , all of which provide fertile ground for accidents to happen.
