What are the current restrictions placed on Pope Francis while he receives treatment for pneumonia?

Pope Francis is currently under strict doctor's orders to rest while receiving treatment for pneumonia at Gemelli Hospital in Rome. No visitors are permitted to see him, with exceptions made only for very close aides who bring official papers and documents for his review and signature. Despite these restrictions, the Pope has been able to maintain some of his duties, reviewing and signing documents brought to him in his special papal suite. His condition appears to be improving, as reports indicate he slept well, enjoyed breakfast, and is able to move around while following medical guidance.
