"I am in agreement with China's decision. It is responsible... Climbing a mountain is not currently worth the transmission risk in the Base Camps, nor upon returning home," Adrian Ballinger of Alpenglow Expeditions said in a statement Wednesday.
Some companies in Nepal have also seen cancellations.
"We had bookings from 23 climbers, but two groups have already cancelled. We might have just 8 to 10 climbers this year," said Pasang Tenje Sherpa of Pioneer Adventure.
A Nepali team, specialised in fixing the climbing route, is currently on its way to the base camp to begin fixing ropes on Everest.
Everest attracts hundreds of mountaineers from all over the world each spring, when a window of good weather opens up between late April and the end of May, prompting a rush for the summit.
Nepal has so far seen only one confirmed case of the coronavirus.
It has suspended visas on arrival for visitors from eight countries badly hit, meaning they have to apply beforehand and submit a health certificate.
