It is 30 years since the discovery of the human immunodeficiency virus (HIV) and it has now spread across the whole of the world. Today some 34 million people are estimated to be carrying the HI virus, which destroys the immune system and triggers the immune deficiency syndrome AIDS. If the condition is left untreated, sufferers will, ultimately, die. Very many of those affected live in developing countries, especially in sub-Saharan Africa, where in some countries nearly 23 million people were infected in 2010. In some countries more than one fifth of adults carry the HI virus. HIV is a threat to the existence of entire societies. It is not only a disaster in human terms, but in economic terms too , and jeopardises sustainable development in the countries affected.
