GASTROINTESTINAL ILLNESS
Gastrointestinal illness is another frequent complaint of expedition climbers throughout the world. The best way to prevent a digestive tract illness is through proper sanitation practices. The National Park Service mountaineering rangers work diligently to maintain a clean mountain environment through education and policy enforcement. Each climber and their team are expected to adhere to the policies outlined on this website and presented at the climber orientations in Talkeetna.
The single best way to combat the spread of gastrointestinal illness is through frequent hand washing and maintenance of personal hygiene. This is best accomplished with traditional soap and water and with alcohol-based hand sanitizers. These products should be utilized frequently especially before cooking and after using the restroom.
