The Chinese Fencing Association announced the three fencers had been diagnosed with coronavirus and are now receiving hospital treatment, as reported by the China Global Television Network.

They returned back to China on March 16 after competing in the Hungarian capital, testing positive upon arrival at the airport. 

"Three team members have been sent to a hospital arranged by Beijing Center for Disease Prevention and Control and are receiving attentive care after exhibiting mild symptoms," the Chinese Fencing Association said.

"Everything is going well so far and we are grateful for all of the support and concern. 

"Other members are in self-isolation with their health conditions being monitored."

Three South Korean fencers also tested positive for coronavirus after a female teammate complained of a sore throat during the same tournament in Budapest, as reported by Yonhap News Agency. 

The South Korean national fencing team and their coaches have now gone into self-isolation for two weeks. 

All qualifying events for the Olympic fencing contest at Tokyo 2020 have now been postponed or cancelled. 

Hungary have 85 cases of coronavirus confirmed so far, with four deaths. 

There are more than 270,000 cases worldwide, with more than 11,000 deaths.
