As part of World AIDS Day the BBC News is running a photo journal entitled: Lesotho Aids diary - Joseph's day.
This gives a great insight into life in some of the more rural places in southern Africa. It also highlights how the likes of Joseph are the real unsung heroes of the battle against HIV.
This article is also part of Lesotho AIDS Diary in which you can learn more about Joseph and some of the other unsung heroes in the battle.
