I spoke myself to a Zimbabwe AIDS specialist recently who says in one area 60% of all pregnant women are now infected with HIV. It is not enough just to look at seroprevalence rates however. Take a group of 100 college leavers in Uganda, aged 22. Their seroprevalence rate is falling because of behaviour change but may still be 20% in some groups. That means one in five will probably be dead in 5-10 years. However, the even bigger question is what the LIFETIME seroprevalence rate will be? 

AIDS - HIV Protease inhibitors promise new hope.

HIV protease inhibitors offer new hope of a combined approach to HIV infection. Results in some cases have been spectacular with undetectable levels of HIV achieved for long periods. This has raised talk of perhaps even being able to eradicate HIV altogether, based on the fact that many infected cells have a limited life-span. By preventing viral replication one could in theory reach a situation where all infected cells had died.

Most of the figures are from UNAIDS or other official sources including reliable in-country surveys. See also video.
