Possible Treatment

There is not a cure YET for HIV. There are, however, treatments to supress the virus from growing. Sometimes, it is effective enough to allow the body time to reproduce a normal amount of T-Cells to strengthen the drepressed immune system.
One treatment is called Antiretroviral Therapy (ART). For this treatment, three or more drugs are taken daily. The drugs are different types so as not to allow the virus to get stronger and immune to the drugs. How well one does depends on their white blood cell count. Those with HIV tend to have a lower count (200 or less than per cubic mm).  Response to treatment also depends on a person's health. Dietary changes may be necessary.  http://www.mayoclinic.com/health/hiv-aids/ds00005/dsection=treatments-and-drugs
