What is HIV? Human Immunodeficiency Virus
What is AIDS? 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. 30 in every 100,000
HIV Geographically
To survive the virus must: Be inside living cells HIV binds to receptors on CD4 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: 1. Blood 2. Semen 3. Vaginal fluids 4. Breast milk
HIV/AIDS transmitted in a variety of ways: 1. Sexual Contact 2. Blood to Blood 3. Incidental cases
Sexual contact: 1. Sexual intercourse 2. Oral Sex 3. Anal Sex
Blood-to-blood contact: 1. Sharing needles or syringes 2. Tattooing 3. Organ donation 4. Accidental needle sticks in medical settings
Incidental cases: 2. Mother's milk to baby 3. During dental procedures 1. Mother to baby during pregnancy or delivery 2. Mother's milk to baby 3. During dental procedures
HIV/AIDS is NOT spread by: A. Casual contact such as kissing, hugging, or sneezing B. Insect bites Saliva (Kissing - no reported cases) Air or Water
Stages & Symptoms: HIV positive asymptomatic stage Middle stage C. HIV symptomatic stage D. AIDS stage
A. HIV Positive Asymptomatic 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.
Still contagious with the virus B. Middle Stage 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
C. HIV symptomatic 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. Fever Night Sweats Fatigue Unexplained persistent diarrhea Loss of appetite and weight loss of 10 lbs. or more in 2 months Swollen lymph nodes Persistent unexplained dry cough or shortness of breath Skin rashes
D. AIDS stage Aids is said to be present when the person develops his/her first opportunistic infection or his/her CD4 level reaches a specific number. CD4 Cell Test: Another factor that determines when a person has AIDS is their CD4 cell count. These are the lymphocytes (WBC) HIV destroys. If the CD4 cell count is 200 or less, the person is said to have entered the stage called AIDS.
per milliliter of blood Normal T-Cell Count 800-1200 T-cell Helpers per milliliter of blood
Opportunistic Infections are: Kaposi’s Sarcoma – an unusual cancer affecting blood vessels (capillaries) causing purplish spots on skin. 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. EIA/ELISA B. Western Blot Test A blood test to locate antibodies for HIV If positive, it is repeated again. May produce a false negative or false positive. B. Western Blot Test An antibody test for HIV done to confirm the results of the ELISA test.
2. Avoiding IV drugs and sharing needles Prevention of AIDS NO-Risk Behaviors: 1. Abstinence 2. Avoiding IV drugs and sharing needles 3. Uninfected monogamous partners
1. Use protection: Latex condoms Decreased Risk: 1. Use protection: Latex condoms 2. Limit the # of partners 3. Have your partner tested for HIV 4. Clean/sterilize your needles
