While filming his new Quibi series, Killing Zac Efron in Papua New Guinea, Zac Efron contracted what is reportedly typhoid or a similar bacterial infection, according to the Sunday Telegraph, via the Australian Associated Press.

WHY IS ZAC EFRON IN HOSPITAL — jems (@ts_jems) December 29, 2019

Per the Telegraph, Efron's flight to Australia was a matter of life or death. Dr Glenn McKay, Director of Medical Rescue, oversaw Efron's emergency flight but could not discuss details with the newspaper. He said that medical professionals "retrieved a US citizen in his 30s from PNG to Brisbane for medical attention in Australia."

Efron was reportedly in stable condition when he made the flight to the hospital.
