Actor Tom Hanks says he and his wife, actress Rita Wilson, have been diagnosed with coronavirus.

In a statement posted to Instagram, Hanks said he and his wife were traveling in Australia when they were tested after exhibiting symptoms like tiredness, body aches, chills and “slight fevers.”

“Not much more to it than a one-day-at-a-time approach, no?” he wrote Wednesday.

A representative for Hanks confirmed the news to CNN and had no additional comment.

Warner Bros. confirmed the actor was in Australia doing pre-production work on a film about singer Elvis Presley.

“We are working closely with the appropriate Australian health agencies to identify and contact anyone who may have come in direct contact with the individual,” Warner Bros. said in a statement. “The health and safety of our company members is always our top priority, and we are taking precautions to protect everyone who works on our productions around the world.”

Hanks is set to play Presley’s manager, Colonel Tom Parker, in the film. Actor Austin Butler is playing Presley. Baz Luhrmann is going to direct.

Hanks said he and his wife will “keep the world posted and updated.”

There are more than 120 confirmed cases of coronavirus in Australia, the World Health Organization said. Prime Minister Scott Morrison’s government announced a $11.4 billion economic plan to support the country’s economy during the epidemic.

The couple’s diagnosis forced Australia’s Nine Network to set up a crisis response plan after Wilson visited the channel’s morning talk show for an appearance Monday. The show airs on CNN’s affiliated Nine Network.

Speaking on Radio 2GB to host Deborah Knight on Thursday, Campbell said he spent about half an hour with Wilson.

“She was delightful, it was really nice, she didn’t seem to have any symptoms of anything, she was very cautious,” he said. “She actually made a joke coming into the studio saying ‘we shouldn’t shake hands we should bump elbows.’ So we bumped elbows.”

Nine Network said staff on the show will be quarantined after coming into “prolonged contact” with the singer and actress.

The famed Sydney Opera House said Wilson performed there Saturday for about 200 people, including her husband. The Opera House got disinfected, and will reach out to people who may have been in contact with the couple.

Campbell said he and his co-host are undergoing testing for coronavirus. He added he will pull his children out of school while awaiting his test results.
