On April 15, a climber at Everest Base Camp became the first known case of COVID-19 documented at the foot of the world’s highest peak. It’s hard to get a complete picture of what the disease is doing at Everest right now, but the situation only appears to be getting worse. “I have taken a helicopter out of EBC back to Kathmandu after 1 day,” Gina Marie Han-Lee, a climber from New York, wrote on Facebook on April 29. “The Covid situation at EBC is a total shitstorm. I had no clue what I was flying into.” On April 28, Polish climber Pawel Michalski also wrote on Facebook that “more than 30 people have already been evacuated with propellers to Kathmandu, with suspicion of pulmonary edema—later found to be positive for coronavirus.”
