Former president Nelson Mandela released the report -
Mandela, who has become a stalwart in the fight against HIV and Aids, commissioned the Human Sciences Research Council (HSRC) to conduct the study under the auspices of the Nelson Mandela Children's Fund and the Nelson Mandela Foundation.
KwaZulu-Natal's HIV prevalence rate for women between the ages of 15 and 49 - the group used to compare prevalence rates - was 11,7 percent.
This was far lower than the estimated 33,5 percent given in the 2001 department of health survery.
The study ranked the
HSRC chief executive Mark Orkin said the survey provided "the most systematic and comprehensive view yet available of how HIV and Aids is affecting South Africans according to race, gender, age and geographical location".
Until recently, most of the country's HIV and Aids prevalence estimates were based on largely unrepresentative data derived from state antenatal clinics and modelled for the wider population.
This study was based on a sample of 9963 people drawn from households across the country, 8428 of whom consented to be tested for HIV and submitted saliva specimens.
Mandela said, overall, the information gained in the study marked a "watershed" in the fight against HIV and Aids.
"I am proud to say we now have the data to tackle the epidemic more vigorously," he said.
This data referred not only to the study's new prevalence data but also to the new data on risk-reducing factors for HIV infection.
These included condom use, the impact of media campaigns and people's perceptions of HIV and Aids.
The study found that HIV prevention messages appear to be having an impact. Among young people between the ages of 15 and 24, 57,1 percent of men and 46,1 percent of women reported condom use at their last sexual encounter - a significant increase from the results of the 1998 health department study.
The study also yielded important differential prevalence rate figures for people living in urban informal settlements compared with those living in urban formal settlement, farms and other rural areas.
People in urban informal settlements had an average infection rate of 28,4 percent while those in urban formal settlements had a 15,8 percent infection rate, those on farms an 11, 3 percent infection rate and those in other rural areas had a 12,4 percent rate.
According to the study's leader, Dr Olive Shisana, HSRC's executive director of social aspects of HIV and Aids, the high infection rate in large informal settlements in the Free State, Gauteng and Western Cape was an issue to be taken into account in future town planning.
Lastly, the study found that the prevalence rate among Africans was the highest - 12,9 percent - while whites and coloureds had a similar 6,2 percent and 6,1 percent prevalence respectively.
The white prevalence rate was high compared to countries such as
The prevalence figure for the South African Indian community was the lowest at 1,6 percent.
"The finding that Africans have a higher than estimated HIV prevalence reflects the historical development of the HIV epidemic in
Two hundred field workers collected the data for the study but people in institutions such as prisons, boarding schools and military barracks were not included in the sample.
The HSRC collaborated with the Medical Research Council, the Centre for Aids Development, Research and Evaluation and the Agence Nationale de Recherche sur le Sida in France during the study. - Sapa
