Now, the star has taken to Twitter to address his hospital dash and thank everyone for their well-wishes.

“Very thankful to everyone who has reached out. I did get sick in Papua New Guinea but I bounced back quick and finished an amazing 3 weeks in P.N.G. I’m home for the holidays with my friends and family. Thanks for all the love and concern, see you in 2020,” the actor wrote.

In fan photos taken on Christmas Eve, Zac could be seen shopping in a store in Los Angeles, wearing a red plaid shirt and cream shorts.

Zac’s new show will follow the 32-year-old actor as he heads to the jungle on a remote island for 21 days and will be "off the grid" with nothing but basic gear and a guide partner.

"I tend to thrive under extreme circumstances and seek out opportunities that challenge me on every level. I am excited to explore any uncharted territory and discover what unexpected adventure awaits!,” Zac said in a statement when he announced the show back in November.

The show is set to air on short-form mobile video platform Quibi, which launches in April, and will also include a horror series from Spielberg called Spielberg's After Dark and reality courtroom show Chrissy's Court with Chrissy Teigen.
