Pope Francis leaves at the end of Easter Sunday Mass inside an empty St. Peter's Basilica, at the Vatican, Sunday, April 12, 2020. Pope Francis and Christians around the world marked a solitary Easter Sunday, forced to celebrate the most joyful day in the liturgical calendar amid the sorrowful reminders of the devastation wrought by the coronavirus pandemic. The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.
