Stage 3: Symptomatic Stage- the stage in which a person infected with HIV has symptoms as a result of immune deficiency. AIDS begins, include: swollen glands, weight loss, and yeast infections.

45. Detecting HIV
EIA- a test that screens of the HIV antibodies in the blood. A. Developing antibodies take 1 month to develop B. Certain health conditions mask antibodies. Western Blot- is the most common confirmation test for HIV. Treatments of HIV: $51,000 per month.
