The 79-year-old Domingo said in a post on his personal Facebook account on Sunday that "I feel it is my moral duty to announce to you that I have tested positive".

The tenor says he and his family are in self-isolation and that he is feeling well despite having fever and a cough.

"I beg everyone to be extremely careful, follow the basic guidelines by washing your hands frequently, keeping at least a 6 foot distance from others, doing everything you can to stop the virus from spreading and please above all stay home if you can!" he said.

Domingo, one of the world's top opera stars, has recently been accused by several women of sexual misconduct.

That has led to several of his performances being cancelled and an apology from him.

Spain is the third hardest-hit country after China and Italy with 28,572 infections and 1720 deaths in the virus outbreak.
