In a post on Instagram, the world number 20 confirmed the positive test and said he and his family were now self-isolating.

"I started my pre-season in Dubai, but unfortunately my wife, my son and myself tested positive for COVID-19," said Khachanov.

"We are self-isolating ourselves and hopefully will be healthy soon.

"I wish everybody to stay healthy and take care of each other."

The 24-year-old's career highlight to date was making the quarter-finals of the French Open last year, where he lost to fourth seed Austrian Dominic Thiem in straight sets.

Shortly after this run, the Russian moved up to a career high of eighth in the world rankings.

He only made the third round at both the Australian Open and US Open this year.

Khachanov has won one Association of Tennis Professionals Masters 1000 title after a straight sets victory over Serbia's world number one Novak Djokovic in the final of the Paris Masters in 2018.

He is one of many tennis players to test positive for the virus, including Djokovic, who contracted COVID-19 during the Adria Tour.

During the tournament, Serbia's Victor Troicki, Bulgaria's Grigor Dimitrov and Croatia's Borna Ćorić also tested positive for the virus.

Romania's world number two Simona Halep is among the other players to have tested positive.
