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!

Australia's Sunday Telegraph reported that Efron contracted what is believed to be typhoid or a "similar bacterial infection" while filming his Quibi show, Killing Zac Efron, in Papua New Guinea.

The Telegraph reported that a medevac crew airlifted the actor to Brisbane, where he was then rushed to a local hospital. 

Efron's doctors cleared him to return to the U.S. on Christmas Eve. 

Efron filmed several films in Louisiana, including The Paperboy and The Lucky One.
