HIV / AIDS Jorge, Maria, Karina, Haidy, and Jennifer
What is HIV? ● Microscopic virus ● Early 1980s: San Francisco, New York, and Los Angeles
Immune System Breakdown ● Leukocytes o White blood cells that defend body ● Antigens o Large molecules that are capable of stimulating the immune system ( Red Flag ) ● Helper T Cells o “read” antigen and begin directing the immune system’s response
AIDS ● CDC established definition of AIDS o must have positive blood count indicating presence of HIV antibodies o T-cell count lower than 200 o cervical cancer/cervical intraepithelial neoplasia (CIN) o Pulmonary Tuberculosis o Recurrent bacterial pneumonia
C onditions Associated with AIDS ● Opportunistic infections ● Cancers ● Clinical Conditions ● Other Infections
Opportunistic Infections ● Certain types of Tuberculosis ● A parasitic disease of the brain or nervous system ● Certain types of Pneumonia o Pneumocytis carinii pneumonia
Cancers ● Cancer of the lymphatic System ● Invasive Cervical Cancer ● Kaposi’s Sarcoma
Clinical Conditions ● Wasting Syndrome ● AIDS Dementia
Other Infections ● Candidiasis (thrush) ● Fungal Infection o respitory system and Vagina ● Colds ● Flu ● intestinal Infection
Transmission “HIV is spread by sexual contact with an infected person, sharing drug injection needles and / or syringes with someone infected…” (CDC, 2007).
Modes of Transmission 1.injection drug use 2.sexual intercourse 3.kissing 4.sex toys 5.mother to child Fluid Exchange: blood, semen, pre-seminal fluid, vaginal fluid, rectal fluid, breast milk Mucous membrane contact Open sores, abrasions, cuts
Modes of Transmission 1.Injection drug use blood-contaminated syringe reuse 2. Sexual intercourse Mucous membrane absorption Anal: rectal lining tear, damage, urethra entry Vaginal: vaginal lining tear, menstrual blood Oral: open sores, cut lips, in mouth ejaculation
Modes of Transmission 3. Kissing bleeding gums, mouth sores, tissue damage, cuts 4. Sex toys vaginal secretions on toys 5. Perinatal HIV transmission ¼ to ⅓ untreated mothers will infect baby child birth breast Milk placenta? NO!
Modes of Transmission Behavioral Factors: Unprotected sexual activities Numerous sexual partners Presence of other STIs
Symptoms Advanced HIV Infection: Oral anomalies Fevers Diarrhea / Weight loss Respiratory problems Vision impairment Skin rashes / itchiness Newly Infected: Asymptomatic period Flu like symptoms
Diagnosis AIDS is a medical diagnosis determined by a physician using the specific CDC criteria (CDC, 2007).
Stages of HIV Infection
Testing ●Who needs to get tested? ●risky behaviors Types of Testing 1.EIA (enzyme immunoassay) 2.Western Blot 3.Rapid Test 4.Home Testing Kits
EIA (enzyme immunoassay) Most common screening test HIV-antibody test If infected with HIV, the body produces antibodies to fight off the virus. The presence of these antibodies concludes a positive test. blood, saliva, urine Results within a couple of days-weeks Reliable If positive, followed up by a Western Blot test
Rapid Test Results in 20 mins Detects HIV antibodies through either blood or saliva Easy to use Accuracy similar to EIA tests Pricing ranges from $14-$26 FDA approved OraQuick Oral swab If positive, follow up with healthcare provider Western Blot → confirmation
Home Testing Kits Home Access HIV-1 Test System Licensed by the FDA in 1997 Procedure Prick finger Place blood on sample card Mail blood sample to designated lab Identification number
Antiretroviral Therapy ● Lowers amount of HIV in body ● Medications used to treat HIV ● Does not cure ● Taken everyday for the rest of the infected person’s life o Slows down the progress of HIV in the body → allows the immune system to repair what has been weaken
Antiretroviral Therapy ● Combination Therapy o Used to decrease the chance of drug resistance
Women and HIV They are vulnerable due to: ● vaginal lining which can tear easily ● mucous membranes that absorb the virus ● age influences likelihood of contracting HIV o younger females have immature cervixes ● urethra can lead virus to blood stream
Possibility of Creating a Family ● Women can still get pregnant if infected with HIV ● About 120, ,000 women in the U.S. have HIV ● 6,000-7,000 of them give birth annually
True or False? An HIV positive mother has greater than 25% chance of infecting her baby with HIV. FALSE
Expecting Mothers & HIV ● 25% chance IF HIV-positive mother is not being treated during pregnancy, labor, or delivery. ● BUT less than 2% IF mother takes preventative measures. ● Early detection and ART → transmission to infant is about 1%
Risk Factors: Perinatal Transmission (Cont.) STD infections Viral load of HIV Factors related to labor and childbirth breastfeeding
Preventing Perinatal Transmission Receiving treatment during and throughout pregnancy Cesarean sections reduce the risk Avoid breastfeeding Refrain from pre-chewing infant food Getting tested!!
A Mother’s Story
Mothers & Children Living With HIV Talk to your children Administer your child’s medication Support!
Living with HIV/AIDS Stay Healthy Do Tell Get Tested! Maintain Positive :)
