A cluster of high-altitude incidents on Mera Peak led to the helicopter evacuations of multiple trekkers suffering from acute medical issues. A 25-year-old climber from Camira, Australia, developed chest tightness at over 20,000 feet and descended with worsening symptoms, including nausea and a persistent cough. He was ultimately diagnosed with acute mountain sickness and bronchitis and treated at a hospital before being released in stable condition.

Elsewhere on the mountain, a member from Skudai, Malaysia, exhibited severe symptoms of AMS and possible HACE after a summit attempt. He was safely medevaced from Khare and received treatment for altitude-related illness and bronchitis.

In a separate incident, a traveler from Singapore sustained bilateral knee injuries after multiple falls on her descent. She was diagnosed with mechanical damage (problems caused by direct blows and sudden movements straining the knees) and discharged after successful evaluation and treatment. These cases highlight the variety of medical risks climbers face on Mera Peak, from respiratory complications to orthopedic trauma.
