Flipped Ratio: The CD4:CD8 ratio is usually approximately 2:1 but in HIV-infected people, the ratio flips and is approximately 1:2.
Set Point: The point around which viral load levels off without anti-HIV treatment. This point is different for different individuals (i.e., rapid progressors generally have higher set points). The idea of treatment is to lower the set point, lowering the viral load in the patient's body.
