  3. MYTHS AND FACTS ABOUT HIV/AIDS

  4. Video: Myths/Facts about HIV

  5. Myth/Fact? HIV is the same as AIDS

  6. HIV vsAIDS

  7. AIDS Criteria (CDC) HIV positive test AND a T-Cell count of <200 or 14% (healthy T-Cell count ranges from 800-1200) OR HIV positive test AND one or more opportunistic infections (OIs)/certain cancers If the T-Cell count goes up, or the opportunistic infection goes away, does the person still have AIDS? YES

  8. HIV & the Immune System HIV attacks the T cells (aka CD4 cells) weakening the immune system Over time HIV can lead to AIDS

  9. Special Characteristics of HIV • Weakens and compromises the immune system • HIV replicates in large quantities • Ability to mutate (change itself) very quickly

  10. Myth/Fact? HIV only affects gay men and drug users

  11. Estimate ~ 60,050 persons living with HIV (including AIDS) in LAC Estimated Number of Persons Living with HIV and AIDS in LAC at End of 2013 13,250 1,500 3,200 9,500 3,200 16,155 50,550 Estimate ~ 61,700 living with HIV & AIDS in LAC 25,895 (1) CDC estimates 15.8% of persons with HIV are unaware of their infection. (2) Reported cases includes half of 3,500 lab reports pending investigation and half of 3,300 cases reported to us only by code likely to result in unduplicated named cases. Source: LAC Division of HIV and STD Programs, reported as of 12/31/13.

  12. Impact on Los Angeles County • LA County is second only to NYC among US metropolitan areas in cumulative number of reported AIDS cases • Only 4 states (CA, TX, NY, FL) have reported more AIDS cases than LAC • 42% of all California AIDS cases are reported from LAC in 2010

  13. Persons living with HIV Infection from HIV/AIDS Annual Surveillance Summary *Reported as of 2011, CDC. HIV Surveillance Report, Volume 23(1), February 28, 2013 ** Reported as of 12/31/12, California Office of AIDS, HIV/AIDS Surveillance Section. *** Report as of 12/31/12, LAC Division of HIV/STD Programs

  14. Transmission Category for Persons Living with HIV/AIDS as of December 31, 2012 by Gender in Los Angeles County Male (n=40,315) Female (n=5,159) * Persons with an undetermined transmission category are assigned a risk factor using multiple imputation (MI) methods. Other risks include hemophilia or coagulation disorder, transfusion recipient, perinatal exposure and confirmed other risk. ** Data are provisional due to reporting delay Source: HIV/AIDS Surveillance Summary, data as of December 2012.

  15. Persons Living with HIV/AIDS in LAC per 100,000 population* by Race/Ethnicity *Sometimes called “Prevalence Rate”; it is really a proportion. Source: HIV/AIDS Surveillance Summary, data as of 12/31/2012.

  16. Myth/Fact? Once a person is diagnosed with HIV/AIDS, they will die soon

  17. HIV Spectrum of Disease Exposure No infection Asymptomatic Infection Window period* Asymptomatic • HIV Illness • Symptoms include: • Night sweats • Fevers • Fatigue • Diarrhea • Swollen lymph nodes • Oral and vaginal candidiasis • PID • Pap Smear positive for HPV • AIDS • T-Cells <200 • 1 or more OIs (PCP, KS, TB, CMV, Candidiasis, etc.) • Wasting syndrome • HIV-related dementia • Initial Symptoms • Lasts a few weeks • Mild flu-like symptoms: • Fever • Muscle aches • Swollen glands Asymptomatic Period 8 - 11 years (Average progression, may vary depending on the person) *Window Period: average time it takes the body to produce antibodies; usually 2 - 12 weeks, up to 6 months - 1 year (rare)

  18. Common Opportunistic Infections • Pneumocystis Carinii Pneumonia (PCP) • CMV Infection • HIV Wasting Syndrome • Candidiasis (oral, esophageal, vaginal) • Kaposi’s Sarcoma • Tuberculosis • HIV - Related Dementia • Cervical Cancer

  19. Myth/Fact? Casual contact CANNOT put you at risk for HIV

  20. You CANNOT get HIV from… • Breathing • Coughing • Sneezing • Kissing • Hugging • Shaking hands • Sharing food or drinks • Drinking fountains • Telephones • Toilet seats • Pools/Tubs • Mosquito bite • Giving/donating blood in US

  21. HIV Transmission Infected Body Fluids HIV is NOT transmitted by urine, feces, saliva, sweat, tears or giving/donating blood. 1 2 3 4 Vaginal Secretions Semen, Pre-cum Breast Milk Blood

  22. HIV Transmission Unprotected Sex 1 2 3 Anal Vaginal Oral

  23. HIV Transmission Exchanging Infected Blood : 1 2 3 4 Insulin, hormone, vitamin shots Injection Drug Use Piercing/ Tattooing Acu-puncture Sharing needles for any purpose

  24. HIV Transmission Mother To Child Transmission during pregnancy (in uterus) during birth process (delivery) breastfeeding (through breast milk/blood) *Perinatal transmission can be significantly reduced to less than 2% with proper care

  25. TIME FOR AN ACTIVITY  “The Spectrum of Risk”

  26. Myth/Fact? Having another STD puts a person at greater risk for contracting HIV

  27. STDs and HIV STDs increase the concentration of “infection fighting” CD4 cells in genital secretions, a favorite target of HIV STDs cause breaks in the skin on and surrounding the penis, vagina and anus, which provides a perfect entry way for HIV STD infection increases risk of contracting HIV (susceptibility) -

  28. STDs and HIV STD infection increases risk of passing HIV to a partner (infectiousness) HIV+ individuals who are also infected with an STD have more HIV in their genital secretions HIV+ men who are also infected with an STD have much more HIV in their semen than HIV+ men without an STD + ? ? ?

  29. Myth/Fact? HIV testing is unnecessary because I would know if my lover or I had it

  30. HIV TEST HIV Antibody test • Looks for antibodies Accuracy of the test • 99.9% Types of tests • Standard test – results will be known in 1 week • Rapid test – results will be known in 20-40mins

  31. HIV TEST Other Test - Uni-Gold Recombigen HIV- results will be known in 10 min. - Reveal G3 Rapid HIV-1 results will be known in 3 minutes - Multispot HIV 1/HIV-2- results will be known in 15 mi. - Clearview HIV 1/2 Stat-Pak - results will be known in 15 mi. - Clearview Complete HIV 1/2- results will be known in 15 mi. - Insti HIV-1- results in as little as 60 seconds • FDA has, for the first time, approved an over-the-counter HIV Rapid test (Oraquick) for home use. Test settings Anonymous Confidential

  32. HIV TEST Informed Consent 12 yrs of age or older Benefits of Testing…….. Where to test? Private medical doctor County clinic Community-based organizations www.hivla.org 1-800-367-AIDS (2437)

  33. Myth/Fact? A person who is HIV positive must tell partners their status

  34. What are the differences between ethical and legal aspects?

  35. California’s “Willful Exposure” Law (1998)aka “Recalcitrant Behavior”: Willfully exposing another to HIV through unprotected sex • 8 years of imprisonment • Intention to infect others with HIV through sex To be prosecuted under the law, one would have to do ALL of the following: • Have anal or vaginal sex • Know that they are HIV + • Fail to disclose their HIV status • Fail to use a condom • Have a specific intent to infect another person Actual knowledge of HIV infection without more evidence of “specific intent” is insufficient for prosecution.

  36. CONFIDENTIALITY LAWS • Disclosing a person’s HIV+ status to a third party without the individual’s specific signed consent, is illegal; • Penalties and damages for unauthorized disclosure of HIV status is a $5,000-$10,000 fine and/or jail sentence.

  37. FEDERAL ANTI-DISCRIMINATION LAWS Rehabilitation Act of 1973 and American with Disabilities Act (ADA) 1990 Prohibits discrimination against a person with a disability, including HIV disease or AIDS. infection. This prohibits discrimination with regards to employment, public services, public accommodations, and medical care. Housing Discrimination Care Discrimination A doctor or dentist cannot refuse to treat an HIV+ person California Anti-Discrimination Laws Fair Employment and Housing Act (FEHA) and Unruh Civil Rights Act

  38. PREVENTION It is not who we are but what we do that puts us at risk for HIV infection

  39. The Prevention “Toolbox” • Abstinence • Safer Sex Male Condom (Activity) Female Condom Dental Dams • Safer Needle Use Not Sharing Needles Cleaning Needles (3x3x3 Method) Needle Exchange • HarmReduction

  40. PREVENTION: Abstinence Abstinence:not having sex of any kind or sharing needles. Not exchanging any bodily fluids is the only 100% sure way to avoid becoming infected with HIV. If one is not going to abstain, what other options do they have?

  41. PREVENTION: Needle use Needle Exchange van in Berkley, CA

  42. PREVENTION: Standard Precautions Infection control measures that reduce the risk of transmission of blood-born germs from patients to health care workers • Wash hands thoroughly • Wear gloves • Use masks and eye protection • Wear a gown • Carefully handling and disposing of sharp instruments during and after use.

  43. TREATMENT

  44. TREATMENT • Goals of HIV/AIDS treatment: • Reduce HIV-related morbidity and prolong survival, • Improve quality of life, • Restore the immune system, • Suppress the viral load, and • Prevent vertical HIV transmission (mother to child).

  45. TREATMENT What are Anti-retrovirals (ARVs) ? • Anti-retrovirals are drugs that interrupt the HIV replication process and help preserve the health of the immune system • These drugs must be taken in combinations in order to have a lasting effect. The three drug combination is commonly known as a “triple cocktail” • Using a combination of anti-retrovirals creates multiple obstacles to HIV replication. This is designed to keep the virus from replicating freely and reduce the possibility of a mutation.

  46. When to start anti-HIV medications? 2 schools of thought: • Treatment should begin if there are severe symptoms of HIV infection or a diagnosis of AIDS with a CD4 count of 350 cells/mm3 or less • Starting treatment immediately following diagnosis Because of the complexity of selecting and following a regimen, the severity of the side-effects, and the importance of compliance to prevent resistance, it is extremely important to engage patients in treatment decisions.

  47. Current classes of Anti-HIV medications • Nucleoside Reverse Transcriptase Inhibitors (NRTIs) • Non-Nucleoside Reverse Transcriptase Inhibitors (NRTIs) • Protease Inhibitors • Entry inhibitors • Fusion inhibitors • Integrase inhibitors

  48. Who Pays For Treatment? • HMO insurance • Medi-Cal • Medicare Part D • ADAP • Shared cost

  49. Complementary Therapy • General Health Maintenance • Psychological Well-Being • Spiritual Well-Being • Social Well-Being

  50. Recent advancements • Immune based therapies • Maturation inhibitors • Multi-class Combination Products • Gene Therapy • Vaccine
