What are the current restrictions on Pope Francis during his hospitalization for pneumonia?

Pope Francis is under strict doctor's orders to rest while hospitalized with pneumonia in both lungs. No visitors are allowed to see the pontiff except for some very close aides who bring him various papers and documents for review and signature, which he has reportedly been able to handle despite his condition. Despite his busy schedule in recent weeks, the Pope was reluctant to go to the hospital last Friday but was ultimately forced to seek medical attention. Throughout his recovery, he has been able to maintain some of his papal duties from his hospital room, reviewing and signing important documents while following medical advice to ensure proper recovery.
