Dispute over HIV rates in South Africa

>> PlusNews Global | Southern Africa | South Africa | SOUTH AFRICA: Questions about new prevalence survey

Just an excerpt here (from the beginning of the article):

Several prominent demographers and scientists have vigorously refuted Health Minister Manto Tshabalala-Msimang’s claim that South Africa’s HIV epidemic is declining and that the country “may be making some real progress in its response to the HIV epidemic”.

Tshabalala-Msimang’s statement was based on a national survey of HIV prevalence among pregnant women, which researchers are describing as deeply flawed.

The report, posted on the health department’s website on 29 August, states that prevalence among pregnant women fell from 29.1 percent in 2006 to 28 percent in 2007.

Prof Rob Dorrington, a demographer at the University of Cape Town, and his colleague, Prof David Bourne, point out in a letter published in the South African Medical Journal (SAMJ) this week that the 2007 survey employed a methodology not only radically different from that used in 2006, but also “manifestly wrong”.
