Pope Francis, 88, slept well and ate breakfast on Wednesday morning after he was diagnosed with bilateral pneumonia, according to the Vatican.

Pope Francis, who has been hospitalized since last week, was found to have pneumonia in both lungs following a CT scan on Tuesday, the Vatican said, with tests continuing to indicate “a complex picture” for one of the oldest popes in the church’s history.

The 88-year-old pontiff is in good spirits and is grateful for the prayers for his recovery, the Vatican said.
