AIDS/HIV 1. HIV attacks the helper T-Cells 2. Helper T-Cells recognize any foreign pathogen in the body and alert the whole immune system. Destruction of T-Cells systematically destroys the immune system. Opportunistic Disease- infections that occur in individuals who do not have a healthy immune system. HIV infection is progressive—1-12years.

Transmission 1. Sexual Intercourse/ Anal Sex 2. Sharing Needles 3. Mother to Baby 4. Infected blood product

Stages of HIV/AIDS There are 3 Stages to HIV/AIDS Stage 1:Infectious Stage- immediately after contracting virus (3-6weeks): fever, rash headache, body aches, and swollen glands. Stage 2: Asymptomatic Stage- a period of time during which a person infected with HIV has no symptoms, 6-10 years. Stage 3: Symptomatic Stage- the stage in which a person infected with HIV has symptoms as a result of immune deficiency. AIDS begins, S@S include: swollen glands, weight loss, and yeast infections.

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.
