Pope Francis has issued a health update, relying on another priest to speak for him, after the Vatican admitted he was suffering from a "mild flu".

The head of the Catholic Church has said he has a lung inflammation but plans to fly to Dubai this week for a climate conference nonetheless. Francis skipped his weekly Sunday appearance earlier today, not appearing at the window overlooking St Peter’s Square. The day before, the Vatican admitted he was suffering from what it called a mild flu.

Instead, Francis gave the traditional noon blessing in a televised appearance from the chapel in the Vatican hotel where he lives. It isn’t known what anti-viral measures he will be taking for the climate change conference. The elderly are even more at risk from severe effects of flu.
