Again, it's going to depend on the country. The last maternal mortality audit figures for South Africa made it clear that HIV/AIDS was the most common cause of death, except that it's an indirect cause of death. What that really means is that it's not a primary cause. Women might die of something else, but they were HIV positive and had AIDS. Therefore that contributed significantly to why they died. In South Africa, it's huge. In other sub-Saharan African countries, it's also very significant. But you do have to have the data for your country specifically.
What we know is that as few as 15% of pregnant women are tested for HIV, and that this is significant both for them and their newborns. At the same time, we need to be extremely careful that if we are going to introduce screening of women during pregnancy for HIV, it is done in a way that is sensitive to their needs as women in the community and not in a way that will aggravate stigma and discrimination and leave them isolated.
