  2. What Are HIV and AIDS? • Human immunodeficiency virus (HIV) is the virus that primarily affects cells of the immune system and that causes AIDS. • Acquired immune deficiency syndrome (AIDS) is the disease that is caused by the HIV virus, which weakens the immune system.

  3. AIDS Around the World • AIDS is a pandemic, a disease that spreads quickly through human populations all over the world. • Most scientists think HIV originally came from Africa, but this is not a fact.

  4. AIDS Around the World (cont.) • 850,000 to 900,000 people are currently living with HIV in the United States. • Over 300,000 people are currently living with AIDS in the United States. • Teens are one of the fastest-growing groups to become infected with HIV.

  5. How HIV Infects the Body • Helper T Cells (CD4+cells) are the white blood cells that activate the immune response ant that are the primary target cells of HIV infection. • HIV uses helper T cells to make copies of itself, killing the helper T cells in the process. • As helper T cell counts drop, the body loses its ability to fight off other infections and certain cancers. • An opportunistic infection (OI) is an illness due to an organism that causes disease in people with weakened immune systems.

  6. Understanding HIV and AIDS • There are three phases associated with HIV and AIDS. • Phase I: This is the asymptomatic stage, which means the infection is present but there are few or no symptoms. This phase can last 10 years or more. • Phase II: This phase is marked by the beginning or worsening of symptoms as the immune system fails. • Phase III: This phase marks the begging of AIDS. The helper T cell count is 200 or less and AIDS-defining conditions develop, such as opportunistic infections.

  7. Ways That HIV Is Spread • There are 3 main ways that HIV is spread: • Sexual activity • Sharing needles or intravenous equipment • Mother to infant

  8. Testing for HIV • An HIV-antibody test is used to detect HIV antibodies. • A person is considered to be HIV positive if they test positive for HIV twice. • A negative test result can be misleading because antibodies may not be found for 6 months after an infection. • You should get retested after 6 months following a negative test result.

  9. No cure exists for HIV and AIDS. (Treatment can only help an infected person survive longer.) Drug combination therapy is an AIDS treatment program in which patients take more than one drug. Drugs for treating HIV can have severe side effects, can lose their effectiveness over time, are expensive, and require diligence and commitment. Treating HIV and AIDS

  17. Living with HIV Infection • Maintaining good health through treatment, diet, exercise, and rest help delay the progression of HIV to AIDS. • Most HIV-infected people in the early phases can do almost everything they did before they got infected. • People infected with HIV must avoid participating in activities that could expose others to HIV.
