This isn't applicable to people with long standing HIV infections. The doctors here basically used HAART (highly active antiretroviral therapy) which calls for the use of 3 drugs--Usually like 2 nucleoside reverse transcriptase inhibitors (NRTIs) or 2 non-nucleoside reverse transcriptase inhibitors (NNRTIs) paired with a protease inhibitor.
The drugs the doctors used are the same drugs used in thousands of other patients. The difference here, is in the child HIV hadn't had a chance to establish a
latent infection yet. Most people are familiar with the fact that HIV infects CD4 cells, but it also infects various other types of white blood cells with CCR5 and other receptors--like macrophages. The virus is able to lie dormant in these cells for the remainder of the hosts life (as some of these cells will last the rest of the hosts life) and is unaffected by antiretrovirals because the virus is not actively replicating.
So someone like Magic Johnson, who's viral load has been below the level of detection for years, still needs to continue HAART because it is suppressing any latent virus's ability to hop from latent cells to CD4 cells and become active again.
Since in this child latency hadn't been established yet, high doses of HAART was able to knock down the virus enough that the immune system was able to "clean" the virus (or likely clean the virus). The child should probably be retested every so often to see if she is ELISA positive for whatever HIV group her mother had.
The problem with adult HIV infections is in the beginning there are normally no symptoms to make one think they are HIV+ or the symptoms are very mild and "cold" like. The virus can have an incredibly long incubation period, sometimes years in some individuals. So when people are found to be HIV+ the virus has normally run rampant through their body and established latency in areas and cells (like the brain, lymph nodes, macrophages etc).
