This newspaper article extracted from “Gastroenteritis Outbreak Among Mountaineers Climbing the West Buttress Route of Denali—Denali National Park, Alaska, June 2002” by JB MCLaughlin, MD, MPH; BD Gessner, MD, MPH; and AM Bailey, RN, MS. It was published in the Journal of Wilderness and Environmental Medicine, Vol. 16, 92-96 (2005):
http://www.wemjournal.org/wmsonline/?req...2&page=0092 The authors gathered data on 132 climbers on Denali returning to base camp from June 11 – 14, and found that over 25% had experienced diarrhea. They had planned to gather stool samples in an effort to identify the culprit organisms, but could not for several logistical reasons. Reading the paper, several things struck me:
· The human waste problem up there is well-known, and 39% of the climbers stated they had seen snow contaminated with feces in or near at least 1 of their camps, with the 17,200’ camp being most contaminated. Yet
· 78% collected snow for consumption within 10 meters of their camps, and
· 56% said they rarely or never boiled or purified it before consumption.
· Furthermore, 33% said they rarely or never washed their hands after defecation.
Thinking back to articles I have written in the past, this is hardly “drinking smart!”
The authors mentioned three risk factors for contracting diarrhea during the study period: (1) spending 8 or more days at the 17,200’ camp, (2) being a member of a climbing party in which at least 1 other person also had diarrhea, and (3) not receiving disease risk-reduction education while on a guided expedition.
Among other things, the authors recommend "that all mountaineers who climb highly trafficked alpine routes be provided with detailed information on appropriate hygiene and illness-prevention strategies (e.g., washing hands with alcohol-based hand sanitizers containing 60% - 95% alcohol or antiseptic soaps and detergents after every bowel movement and before cooking and eating, using water purification [e.g., iodine] tablets in all water that is used for consumption, and avoiding crowded sleeping arrangements in tents).”
I’m very happy I have already climbed that sucker!
