Question

Quizplus · Accepted Answer

Full-blown AIDS occurs when the concentration of Helper T-cells decreases to a critical level. This allows opportunistic infections to take hold, leading to the symptoms of AIDS. The decrease in Helper T-cells is caused by the destruction of these cells by the HIV virus. CD4 receptors and immunity to HIV do not directly correlate with the development of AIDS. The concentration of the HIV virus in the body may decrease temporarily with treatment, but this does not prevent the progression of the disease if Helper T-cell levels continue to decline.
