Pope Francis did not receive anyone in audience on Friday because he has a fever, the Vatican said Friday.

Vatican spokesman Matteo Bruni did not provide further details on the health of the 86-year-old Roman Catholic leader.

«Due to a fever, Pope Francis did not receive (anyone) in audience this morning,» Bruni said in response to a reporter’s question as to why no one was on his daily schedule earlier in the day.

Francis spent five days in a Rome hospital in late March with bronchitis, but made a quick recovery after an infusion of antibiotics and returned to duty, including a three-day trip to Hungary in late April.

He appeared to be fatigued at a meeting with students near the Vatican on Thursday afternoon.

Francis, who became Pope 10 years ago, is missing part of a lung. It was taken from him when he was young in his native Argentina.

None of the events scheduled by the pope have been canceled and he is due to preside over a Pentecost Mass on Sunday in St. Peter’s Square.

It was not clear if he would hold private hearings on Saturday.
