Tom Hanks and Rita Wilson shared an update from Australia, where they are both in isolation after testing positive for coronavirus.

Hanks tweeted a picture with his wife Thursday night, thanking those who’ve cared for them as they battle the virus. “Hello folks. Rita Wilson and I want to thank everyone here Down Under who are taking such good care of us. We have Covid-19 and are in isolation so we do not spread it to anyone else,” he said.

“There are those for whom it could lead to a very serious illness. We are taking it one-day-at-a-time. There are things we can all do to get through this by following the advice of experts and taking care of ourselves and each other, no?”

Just a day earlier, the couple posted that they tested positive after exhibiting symptoms like tiredness, body aches, chills and slight fevers.

“Well, now. What to do next? The Medical Officials have protocols that must be followed. We Hanks’ will be tested, observed, and isolated for as long as public health and safety requires. Not much more to it than a one-day-at-a-time approach, no?” he wrote.

Wilson also posted a light-hearted tweet writing, “From here on out, the only Corona I want is from Mexico and you drink it.”

Warner Bros. confirmed the actor was in Australia doing pre-production work on a film about singer Elvis Presley. Hanks is set to play Presley’s manager, Colonel Tom Parker, in the film. Actor Austin Butler is playing Presley.

According to the World Health Organization, there are currently more than 120 confirmed cases of coronavirus in Australia. Prime Minister Scott Morrison’s government announced a $11.4 billion economic plan to support the country’s economy “as the world deals with the significant challenges posed by the spread of the coronavirus.”

The star couple’s diagnosis forced Australia’s Nine Network to enact what it called a “crisis response plan,” as Wilson had visited the channel’s morning talk show “Today Extra” for an appearance with hosts David Campbell and Belinda Russell on Monday. The show airs on CNN’s affiliated Nine Network.

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

“Our premises is currently being thoroughly cleaned in all areas she visited and we are encouraging our employees to monitor their health and practice good hygiene,” the network said.
