A 38-year-old member from Australia became acutely ill at Urdukas Base Camp on the K2 trekking route. She presented with fever, vomiting, dehydration and difficulty walking, symptoms indicating a systemic infection. A fellow trekker and physician assessed her condition and identified low oxygen saturation and elevated heart rate, prompting a recommendation for urgent evacuation. Initial plans were delayed due to poor weather, but Global Rescue successfully coordinated helicopter evacuation from Paiyu Army Camp to Skardu once conditions allowed. Upon arrival, she was admitted to a hospital where she received IV fluids, antibiotics and supportive care. Her health improved over the next 24 hours and she was discharged in stable condition. She declined additional monitoring but expressed gratitude for the assistance. This case reflects the dangers of infection during high-altitude trekking and the importance of early intervention when access to care is limited by weather and geography.
