RIO DE JANEIRO - Brazilian tennis player Thiago Wild has tested positive for the coronavirus, less than a month after winning his first ATP title.

The 20-year-old said he is making a good recovery, having fallen ill with fever and flu-like symptoms early last week.

"Hey, guys, I just want to let you know that I've contracted the COVID-19. I've been in self-isolation for the past week and now I'm following the doctor's orders by taking care of myself," Wild said in a video posted on social media on Wednesday.

Wild became the youngest Brazilian to win an ATP title when he clinched the Chile Open earlier this month, aged 19 years and 257 days.

The world No 114 urged people to take the disease seriously by avoiding social contact.

"It's important to stay at home and take care. This is a serious illness but it can be controlled with everybody's help," he added.
