Pope Leo is set to visit four African countries, including Uganda, where over 20% of the world's Catholics live. His trip is part of an effort to encourage world leaders to address the needs of the continent. Pope Paul VI made the first papal visit to Africa in 1969, and Pope John Paul II made 15 visits and was the last pope to visit Equatorial Guinea in 1982. Pope Benedict made two visits to Africa, and his comment on the Church's ban on Catholics using condoms to combat HIV/AIDS sparked international outcry. A visit to the Central African Republic in 2015 was the first time a pope had travelled to an active war zone.
