A 54-year-old member from Broadstairs, United Kingdom, was at Barafu Camp on Mount Kilimanjaro in Tanzania when she developed symptoms of acute mountain sickness, including dizziness and severe headache. Her vital signs showed low blood oxygen levels and a fast heart rate. Because she and another climber at the same location were both unwell, the operations team approved a combined helicopter evacuation to a medical center. There they were evaluated, treated for altitude illness and discharged once stable.
