Acquired Immunodeficiency Syndrome
HIV/AIDS by the #’s 12 million people who have HIV/AIDS are in the 15 -24 age group 1/5 all new HIV infections are among young people aged 13 -24. Every day about 6, 000 people become infected with HIV. 17% of all new HIV diagnosis in the United States occur in the South Georgia highest rate of diagnosis in U. S. 1 in every 51 persons
HIV Geographically
Be inside living cells HIV binds to receptors on CD 4 cells (Helper T Cells) and uses its DNA to assemble long chains of noninfectious HIV proteins which later become infections HIV.
4 body fluids can carry the virus:
HIV/AIDS transmitted in a variety of ways:
Sexual contact:
Blood-to-blood contact:
Incidental cases:
A. HIV positive asymptomatic stage B. Middle stage C. HIV symptomatic stage D. AIDS stage
The person can have HIV in his/her body for 10 years or more, but feels healthy with NO Symptoms. Low levels of virus in blood. Still contagious with the virus Incubation period for HIV is 6 weeks to 6 months. This is the amount of time it takes for your body to begin making antibodies for HIV.
Patients experience acute infections such as fever, headache, sore throat, rash, diarrhea, and enlarged lymph nodes. Sometimes called acute HIV Infection stage. Still contagious with the virus
Immune system is badly damaged by the virus. Lymph nodes damaged, increased t cell destruction which the body fails to keep up with. Sometimes called chronic HIV stage. 1. Fever 2. Night Sweats 3. Fatigue 4. Unexplained persistent diarrhea 5. Loss of appetite and weight loss of 10 lbs. or more in 2 months 6. Swollen lymph nodes 7. Persistent unexplained dry cough or shortness of breath 8. Skin rashes
Aids is said to be present when the person develops his/her first opportunistic infection or his/her CD 4 level reaches a specific number. CD 4 Cell Test: Another factor that determines when a person has AIDS is their CD 4 cell count. These are the lymphocytes (WBC) HIV destroys. If the CD 4 cell count is 200 or less, the person is said to have entered the stage called AIDS.
Normal T-Cell Count 800 -1200 T-cell Helpers per milliliter of blood
1. Kaposi’s Sarcoma – an unusual cancer affecting blood vessels (capillaries) causing purplish spots on skin. 2. Pneumocystis Pneumonia (PCP) – caused by a fungus that infects the lungs. 3. Lymphomas – cancer of the lymph nodes. 4. AIDS-related dementia (ARD) – damage to the brain and spinal cord causing memory loss, depression and loss of judgment. 5. SLIM disease (Wasting Syndrome) – severe weight loss (10% of body weight)
A blood test to locate antibodies for HIV If positive, it is repeated again. May produce a false negative or false positive. A test to detect HIV specific antibodies done to confirm the results of the ELISA test (99. 9% accurate).
NO-Risk Behaviors:
Decreased Risk:
Being infected with HIV is the same as having the disease AIDS.
People infected with HIV usually die within 6 months.
After AIDS symptoms develop, most victims die within 2 years.
The HIV virus can be spread by coughing or sneezing.
AIDS is a unique infectious disease because the immune system cannot fight it off.
Name 2 ways AIDS can be transmitted.
List one opportunistic infection.
Name one way you cannot spread the disease of AIDS.
