Covid storm engulfs Everest

Mount Everest guide Buddhi Bahadur Lama has spent days isolated in a tent after testing positive for coronavirus, as an outbreak that climbers say is putting lives at risk sweeps base camp. He is one of four in his expedition team thought to have contracted Covid-19 at the foot of the world's highest mountain, along with a growing number of others. Dozens of suspected Covid cases have been flown out of the area and at least two companies have cancelled expeditions after team members tested positive. However authorities in Nepal have yet to acknowledge a single case at the mountain, with the stakes high for the country's tourism industry. The country is reporting an average of 8,000 cases a day and the health system has been overwhelmed.
