Covid cases at Everest base camp raise fears of serious outbreak

Mountaineers and authorities at Everest base camp in Nepal have told the BBC they are seeing rising numbers of climbers with Covid-19 symptoms and rising numbers of positive tests, raising fears of a serious outbreak.

Base camp officials said they had received reports of 17 confirmed cases from hospitals in the capital Kathmandu, where a number of climbers have been sent from the base camp and higher camps to be treated.

And staff at a private hospital in Kathmandu, the CIWEC clinic, confirmed to the BBC that patients had tested positive for coronavirus after arriving from Everest base camp. 

The Nepalese government has so far denied having any knowledge of positive cases at Everest base camp, raising concerns that officials are downplaying the extent of the situation out of fear it will bring more pressure to close the mountain to expeditions.
