Republic of South Africa is the country at the southern tip of Africa. It borders the Atlantic and Indian oceans and Namibia, Botswana, Zimbabwe, Mozambique, Swaziland, and Lesotho, an independent enclave surrounded by South African territory. South Africa is a member of the Commonwealth of Nations. The South African economy is the largest in Africa and 24th largest in the world. Due to this it is the most socially, economically and infrastructurally developed country on the continent.

South Africa has experienced a different history from other nations in Africa because of early immigration from Europe and the strategic importance of the Cape Sea Route. The country's relatively developed infrastructure made its mineral wealth available and important to Western interests, particularly throughout the late nineteenth century and, with international competition and rivalry, during the Cold War. South Africa is ethnically diverse, with the largest Caucasian, Indian, and racially mixed communities in Africa. Black South Africans, who speak nine officially recognised languages, and many more dialects, account for slightly less than 80% of the population.

Racial strife between the white minority and the black majority has played a large part in South Africa's history and politics, culminating in apartheid, which was instituted in 1948 by the National Party (although segregation existed before that time). The laws that defined apartheid began to be repealed or abolished by the National Party in 1990, after a long and sometimes violent struggle (including economic sanctions from the international community) by the Black majority as well as many White, Coloured, and Indian South Africans^{[citation needed]}.

HIV/AIDS
The spread of AIDS (acquired immuno-deficiency syndrome) is an alarming problem in South Africa with up to 31% of pregnant women found to be HIV infected in 2005 and the infection rate among adults estimated at 20%.^[42] The link between HIV, a virus spread primarily by sexual contact, and AIDS has long been denied by the president and the health minister, who have insisted that the many deaths in the country are due to malnutrition, and hence poverty, and not HIV.^[43] Recently, in 2007, the government made efforts to fight AIDS.^[44].

AIDS affects mainly those who are sexually active and is far more prevalent in the black population. Most deaths are people who are also economically active, resulting in many families losing their primary wage earners. This has resulted in many 'AIDS orphans' who in many cases depend on the state for care and financial support.^[45] It is estimated that there are 1,200,000 orphans in South Africa.^[45] Many elderly people also lose the support from lost younger members of their family. Roughly 5 million people are infected with the disease.^[46]

Malaria
According to Statistics South Africa, malaria death rates increased between 1997 and 1999, and decreased between 1999 and 2004. That said, deaths from malaria among males increased 45% between 1997 and 2004, and among females it increased 93% during the same period.^[47]
