The ex-Red Devil is the first Chinese Super League player to be diagnosed with the virus.
Marouane Fellaini has tested positive for coronavirus in the Chinese province of Jinan, according to a local health department.
The former Everton and Manchester United player is currently lining up for Chinese Super (CSL) side Shandong Luneng and arrived by train in Jinan on March 20 when the positive test was taken.
Fellaini, 32, is the first CSL player to test positive for coronavirus to date, with that competition, like around the world, currently suspended indefinitely.
Taking to Twitter on Sunday morning, the Belgian said: “Dear friends, I have been tested for coronavirus and my test result is positive.
“Thanks to the fans, medical staff and the club for their care and attention. I will follow the treatment and hope to return to the game as soon as possible. Please everyone stay safe.”
