For centuries, one of the biggest taboos at the Vatican was openly discussing the pope's health. As leader of the world's 1.4 billion Catholics, the pope is a revered spiritual figure. Talking about his earthly health was profane.

Thousands of people gathered in St. Peter’s Square to pray for an ailing Pope Francis, expressing sorrow for his suffering, hope for his recovery and gratitude for his efforts to steer the Catholic Church in new directions.

The Holy See Press Office provided an update on Pope Francis's health on Tuesday evening, stating he has not suffered acute respiratory episodes, and his hemodynamic parameters remain stable, Vatican News reported.
