damage caused by HIV/AIDS remains substantial as older age groups continue to develop new infections, with a high percentage of deaths.


Although the education of people about the disease continues to increase, only 30 per cent of South Africans over 50 years of age are aware of the true causes of the disease. Between the ages 25–49, a little over half take protective measures (e.g. use of barrier contraceptives/condoms), with this figure rising to over 90 per cent for those under 25. While this shows a move in the right direction for South Africa, it will take many decades before HIV/AIDS becomes a less prevalent issue.


In 2006 the then South African Minister of Health suggested that eating foods such as olive oil, lemon and garlic would cure people of HIV and AIDS.


In 1996 South Africa’s soccer team showed their support for the campaign raising AIDS awareness at the African Nations Cup by wearing red ribbons.
