Queueing at top of the world: Climbers are scaling Everest in record numbers despite Covid outbreaks


Climbers have been scaling Mount Everest in record numbers this spring, forming queues to the summit amid a surge in coronavirus cases in one of the most dangerous seasons experts can remember.

The pandemic forced a complete shutdown of Nepal’s mountaineering industry last year, creating a backlog of intrepid explorers keen to take on the 29,000ft peak.

Even as China’s side of the mountain remained closed, Nepal issued a record 408 permits to ascend Everest, worth about £3 million. 

Quarantine restriction were eased to promote the climbing rebound, but there was soon a surge in cases, peaking at more than 9,000 in mid-May, and a new strain of Covid-19 known as the Nepal variant emerged.

The mutation, which scientists fear combines the most devastating traits of the Indian and South African variants, has been detected in the UK, the US, India and Portugal, and has been traced back to flights out of Nepal.

It is unclear whether the Nepalese variant was behind an outbreak at Base Camp at the end of May that saw at least 100 mountaineers infected by the virus. 

Still mountain guides like Lakpa Sherpa, who has ascended the summit seven times, decided he had to persevere with the expeditions his Pioneer Adventure had booked for 23 clients.

‘This season was very difficult. We were already working under pressure because of Covid, and then the weather also betrayed us,’ he told AFP.

The warmer window that usually ushers in safer conditions for scaling Everest and other Himalayan peaks coincided with a deadly second wave of virus infections in Nepal, with reports of more than 9,000 daily cases in May.

Dozens of climbers are lined up close to the summit of Mount Everest in Nepal on May 12. Quarantine restrictions were eased to promote the climbing rebound, but there were also no clear plans to test for, isolate or control an outbreak. While summiting the mountain was already deadly, it had become even more dangerous.

There was a record 9,317 cases reported on May 11 as hordes of mountaineers began taking to the peak for the spring high season

‘There used to be coughs, common colds and a risk of getting into avalanches and crevasses in the past. But this year, the danger was if we got infected from Covid we would not be able to climb up because it makes breathing difficult and causes fatigue,’ said guide Mingma Dorji Sherpa. 

Despite precautions that teams tried to take – including masking, sanitising and isolating – virus cases began to spread.

Public Health England's weekly report found the variant had been spotted 43 times in Britain so far, up from the 29 last week

Pilots in PPE suits arrived to evacuate dozens of suspected Covid-19 patients out of the area and at least two companies cancelled expeditions after team members tested positive.

Many climbers confirmed their diagnosis on social media and blogs, including some who had reached the summit.

When Icelandic duo Sigurdur Sveinsson and Heimir Hallgrimsson began coughing as they reached around 23,000ft, they suspected they had caught the virus. Still, they made it to the summit 29,000ft above sea level.

Their symptoms became stronger as they descended.

‘In camp 2, we were both very sick from coughing, headaches and other fatigue. We suspected that not everything was perfect and we needed to get down as fast as possible,’ they said in a statement last Thursday.

They said they both tested positive on reaching the base camp, and isolated in their tents.

Yet authorities in Nepal have not acknowledged a single case at the mountain, with the stakes high after last year’s shutdown cost one of Asia’s poorest countries millions in lost revenue. Porters and guides for well-heeled foreign climbers were left without income.

It was the third time in the last decade that Everest’s summit sat empty. Climbers abandoned the mountain after the 2015 earthquake triggered an avalanche killing 18 people.

In 2014, an avalanche claimed the lives of 16 Nepali guides on the infamous Khumbu icefall, forcing organisers to cancel expeditions.

Lukas Furtenbach, who was the first to call off his expedition because of Covid-19 outbreaks, says the government should extend the validity of the £7,800 licence his clients purchased to climb Everest.

‘Nepal invited foreign expeditions to come and assured us of Covid safety… And my clients did not feel safe at the base camp,’ he said.

Expedition organisers have also self-censored, leaving no way to estimate the actual number of cases among Everest climbers and guides.

‘There is no excuse for the blatant lies, denials, and cover-ups committed by the (government) this season,’ mountaineering blogger Alan Arnette wrote on Friday.

‘Do they understand that their actions only undermine the very credibility they need to effectively manage their resources?’

Those willing to risk coronavirus infections faced a curtailed window to climb. The government put limits on the number of climbers who could scale at any given time to avoid a traffic jam on the peak, and two cyclones that hit India in May further restricted the three-month season.

When the second of those cyclones hit eastern India last week, it caused a huge snowstorm on Everest, burying the tents of the last lot of climbers waiting to summit.

Final numbers are yet to be announced, but the tourism department estimates that around 400 climbers reached the summit this year, far less than the 644 in 2019 when fewer permits were issued.

German climber Billi Bierling, who manages a database that records summits, said that the events of this year are unlikely to dim interest in Everest.

‘Maybe we will think about it and reflect on what happened in 2021, but once this is over, expedition operators and climbers will be coming back.’  

What do we know about the ‘Nepal variant’? 

Real name: Delta+K417N

When and where was it discovered?

The mutant strain is thought to have first emerged in Nepal after the Indian variant mutated.

Scientists believe the country is the most likely origin of the virus because of its similarities to the Indian variant, and the detection of so many cases on flights from the Himalayan nation.

Only one case has been identified in Nepal, but the country carries out very little Covid surveillance. 

What mutations does it have?

The variant is a mutated version of the Indian variant but with a new mutation — called K417N — which has also been spotted on the South African variant. 

Is it more infectious and can it evade vaccines?

There are no studies at present showing whether it is more infectious or can evade vaccines compared to other variants.

But scientists fear it has combined the worst features of the the Indian and South African variants, making it more transmissible and more resistant to vaccines. 

Some experts have warned, however, that Britain must stop ‘scampering down rabbit holes’ every time a new variant is detected. 

Professor Lawrence Young, a virologist at Warwick University, said: ‘We need to change our attitude to variants and not panic every time a new variant is identified.

‘Virus variants are generated by every one who is infected and this will continue as more people are infected around the world.’

How deadly is it?

It is not clear whether the mutant strain is more deadly, but it is being watched closely by scientists.

Studies suggest the Indian variant is not more deadly than the original virus.

How many cases have been detected in the UK?

Forty-three cases have been identified in the country, PHE’s surveillance report from last week shows. The number is now thought to be higher.

The variant had arrived on British soil by April 24, sequencing data suggests.
