A patient comes into the clinic and after testing, you discover that she has a normal T-cell count in combination with a high HIV viral load. What part of the natural history of HIV infection is she in? Describe the progression of an HIV infection over time with regard to the number of circulating viruses, host antibodies, and CD4 T cells.

Step 1
The patient has a normal T-cell count, which means her CD4 T cells are not significantly depleted yet. Show more…

A patient at a clinic has tested positive for HIV. Her blood contained $700 / \mu \mathrm{L}$ CD4 $\mathrm{T}$ cells and she does not have any apparent illness. Her infection is in which stage? a. 1 b. 2 c. 3
A typical person has 500 to $1500 \mathrm{~T}$ cells per drop of blood in the body. HIV destroys the $\mathrm{T}$ cell count at a rate of $50-100$ cells per drop of blood per year, depending on how aggressive it is in the body. Generally, the onset of AIDS occurs once the body's $\mathrm{T}$ cell count drops below 200 . Write a sequence that represents the total number of $\mathrm{T}$ cells in a person infected with HIV. Assume that before infection the person has a $1000 \mathrm{~T}$ cell count $\left(a_{0}=1000\right)$ and the rate at which the infection spreads corresponds to a loss of 75 T cells per drop of blood per year. How much time will elapse until this person has full-blown AIDS?
