Thursday night, Hanks, 63, posted a new picture on Instagram with Wilson, also 63, both in baseball caps.
The Oscar winner, who is in Australia for pre-production of a film about Elvis Presley, announced Wednesday that he and his wife had contracted the virus. He opened his message by thanking everyone helping take care of them in isolation.
“We have Covid-19 and are in isolation so we do not spread it to anyone else. There are those for whom it could lead to a very serious illness,” he said. “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?”
Hanks ended the note with a famous quote from “A League of Their Own," the 1992 classic in which he portrayed baseball manager Jimmy Dugan.
“Remember, despite all the current events, there is no crying in baseball,” he wrote.
Wilson posted the same picture and thanked fans for their support.
"So grateful for the outpouring of prayers, love and support," she wrote. "Means so much and strengthens us."
Wilson also cracked a joke about her diagnosis on Twitter, writing, "From here on out, the only Corona I want is from Mexico and you drink it."
Earlier Thursday, Hanks' "Toy Story" co-star Tim Allen sent some lighthearted encouragement to the couple over social media.
"I told Tom and Rita that Buzz offered a couple of spacesuits if they need them," Allen tweeted alongside a photo of his character from the series, Buzz Lightyear. "Seriously rest up and get well!"
In an Instagram video, Chet Hanks, Hanks and Wilson's older son, told fans his parents were "not really worried" about the diagnosis.
"I appreciate everyone’s concern and the well-wishes but I think it’s all going to be all right," he said.
