Namibia has a population of 2.1 million people....
Given the presence of the arid Namib Desert, it is one of the least densely populated countries in the world. Approximately half the population live below the international poverty line, and the nation has suffered heavily from the effects of HIV/AIDS, with 15% of the adult population infected with HIV in 2007.

HIV/AIDS in Namibia is a critical public health issue. The prevalence of HIV in Namibia is among the highest in the world. Since 1996, HIV has been the leading cause of death in the country. Close to 17 per cent of the country’s children under the age of 18 are orphaned by at least one parent – mostly due to HIV.[1] Consequently, life expectancy has declined since independence from 61 years (in 1991) to 49 years in 2001.[2]

In Namibia, HIV is mainly spread through heterosexual sex, driven by high rates of multiple and concurrent partnerships, transactional sex and child abuse, misconceptions in the general population about the risk of contracting HIV, low and inconsistent condom use, low rates of male circumcision, high rates of alcohol abuse, a high rate of mobility and migration, and a decline in marital and cohabiting unions.[3] Of greatest concern to many are the AIDS orphans and vulnerable children left behind in the trails of this disease.
