Pope Francis attends the Ash Wednesday mass which opens Lent, the forty-day period of abstinence and deprivation for Christians before Holy Week and Easter, on February 26, 2020, at the Santa Sabina church in Rome. - Pope Francis postponed his official appointments on February 28 and was working from home, the Vatican said, a day after cancelling a scheduled appearance at mass because of "a mild ailment". Francis, 83, had appeared earlier in the week to be suffering from a cold. He was seen blowing his nose and coughing during the Ash Wednesday service, and his voice sounded hoarse.
