There are drugs that inhibit the HIV virus, making it less active.
They are known as anti-retroviral drugs (ARV's).
You can take these drugs to delay or prevent developing AIDS.
But there are no drugs that can rid your body of the virus completely. Nor is there a vaccination against HIV.
Once you are HIV infected you need to take anti-retroviral drugs for the rest of your life, and do this as the doctor prescribes.
ARV's are sometimes known as Highly Active Anti-Retroviral Therapy (HAART) or Anti-Retroviral Therapies (ART's). ARV's, HAART and ART's refer to the same thing.
