US actor Tom Hanks said he and his wife, actress Rita Wilson, had tested positive after they felt tired with slight fevers in Australia, where he is working on a film.

"To play things right, as is needed in the world right now, we were tested for the coronavirus and were found to be positive," Hanks, 63, said in a tweet.

He said that he and Wilson, also 63, would be "tested, observed and isolated for as long as public health and safety requires".
