Advancing HIV/AIDS Prevention in Native Communities What Is HIV? H: Human, because this virus can only infect human beings I: Immuno-deficiency, because the effect of the virus is to create a deficiency within the body’s immune system V: Virus, because this organism is a virus, which means one of its characteristics is that it is incapable of reproducing by itself. It reproduces by taking over the human cell How Is HIV Spread? HIV must be present and in sufficient quantity (in blood very concentrated) and it must enter the bloodstream What Is AIDS? A: Acquired, because it’s a condition one must acquire, not something transmitted through genetics I: Immune, because it affects the body’s immune system, the part of the body which usually works to fight off germs such as bacteria and viruses D: Deficiency, because it makes the immune system deficient S: Syndrome, because someone with AIDS may experience a wide range of different diseases and opportunistic infections CDC Definition Of AIDS Has changed over the years and includes the following conditions: HIV positive, AND CDC (T-Cell) count below 200, OR presence of one or more opportunistic infections ~ Kaposi’s Sarcoma ~ AIDS Dementia ~ TB outside of the lung ~ Pulmonary TB ~ Recurring bacterial pneumonia ~ Invasive cervical cancer, etc. HIV Survival Outside The Body Length of time depends on: Amount of HIV present in the body fluid What conditions the fluid is subjected to HIV is very fragile, and many common substances like hot water, soap, bleach and alcohol will kill it HIV Survival Outside The Body Minimal chance of being infected by handling a body fluid w/HIV unless it enters the bloodstream through broken skin or touches mucous membranes (like around eyes) Air does not kill HIV, but dries the fluid that contains the virus thus destroying it HIV can survive for several days in small amounts of blood found in needles. Needles are very risky for transmission! Where Is HIV Found In The Body? Possibly infectious “bodily fluids” Pre-seminal fluid Pre-seminal fluid presents a much lower risk for HIV transmission than fluid from ejaculation, but there is some risk, depending on where this fluid is deposited Where Is HIV Found In The Body? Infectious “Bodily Fluids” ~ Blood (including menstrual blood) ~ Semen ~ Vaginal secretions ~ Breast Milk Blood contains the highest concentration of the virus, followed by semen, then vaginal fluids. Breast milk is a means of transmission for infants. Non-infectious “Bodily Fluids” Saliva Tears Sweat Feces Urine Activities That Promote HIV Transmission Unprotected sexual contact (body fluids) Direct blood contact Drug injection, blood transfusion, health accident Mother to Baby (before or during birth, or through breast milk) Sexual Routes Of Transmission Sexual intercourse (vaginal & anal) - HIV may infect the mucous membranes directly or enter through cuts/sores Oral sex - Some what lower risk due to enzymes, acids, air, which destroy the virus, etc Heterosexual transmission – From Males to Females is higher than from Females to Males Non-sexual Routes Of Transmission Sharing injection needles Needle sticks Blood transfusions Hemophilia treatments Other blood products, i.e. platelets-red blood cells Mother to child Donor insemination HIV is NOT Transmitted By.. Insect bites -mosquitoes, flies, ticks, fleas, bees, or wasps Casual contact/sharing dishes or food (not transmitted by saliva) Donating blood (sterile needles) Swimming pools/hot tubs (chemicals kill) House Pets (cats, dogs) Saliva/tears/sweat/feces/urine Transmission through tattooing, piercing, acupuncture, electrolysis and shaving When needles or razors are used on more than one person, there is a risk BUT the risk can be reduced by using sterilization procedures. No documentation in the U.S. of being infected through tattooing or piercing CDC Created Guidelines Any instruments designed to penetrate the skin such as tattoo or acupuncture needles should be used once and discarded or thoroughly cleaned and sterilized after each use Treatment : Three Primary Approaches Antiviral Therapy ~ Goal is to stop HIV replication with use of drugs such as AZT and Protease inhibitors Immune boosting therapy ~ Attempt to bolster the body’s ability to fight HIV and/or fortify immune system (vaccines) Treatment & prevention of specific infections ~ Many infections can be controlled, prevented or eliminated Monitoring The Immune System When to begin: if one is asymptomatic and before the T-cell count declines Contact a testing site for a physician referral Find a doctor who is familiar with treating HIV disease Tests That Monitor the Immune System HIV viral load – measures amount of HIV in blood plasma CD4 count – measures the number of CD 4 cells in blood sample. CD4 count is one indicator of how much damage HIV has caused the immune system. CD8 count- higher count indicates lower immune function Immune Monitoring Tests A doctor MUST order the monitoring tests and interpret the results Interpreting CD4 (T-Cell) Results Most Doctors Agree: ~ Greater than 500 T-cells normal ~ Between 200-500 indicate immunodeficiency ~ Less than 200 indicates severe immunodeficiency (and is the basis for an AIDS diagnosis) Single count does not count, should have 3 tests When To Begin Treatment Most recommend when— ~ CD4 count less than 500 ~ Viral load is greater than 10,000 copies/ml Natural Approaches Chinese herbal remedies Native Spiritual healers and herbalists Massage Acupuncture Healthy diet Ceremony Global Summary Of HIV/AIDS (as of the end of November 2007) Number of People living with HIV/AIDS Total………………………………….............33.2 million Adults………………………………………..…30.8 million Children under 15 years old……..2.5 million (women account for nearly 1/2 of all people worldwide living with HIV/AIDS) UNAIDS & World Health Organization. (2007). AIDS epidemic update: December 2007. HIV/AIDS In The US It is estimated that 1.2 million people are living with HIV and 25% of those are unaware of their status Of the new HIV infections each year: 74% are diagnosed among males 26% among females Cumulative estimated # of AIDS cases through December 2006 by race/ethnicity 409,982 42% White Black 161,505 17% Hispanic API 394,024 40% 7,951 1% AI/AN 3,345 <1% Centers for Disease Control and Prevention, Basic Statistics, http://www.cdc.gov/hiv/topics/surveillance/basic.htm#aidsrace, June 2007 20 20 20 20 20 20 20 19 19 19 19 19 19 19 19 19 19 19 19 19 19 06 05 04 03 02 01 00 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 8 44 2 32 19 3500 45 33 8 3 32 84 30 26 30 75 28 3000 37 25 37 23 2500 32 21 40 19 2000 83 17 69 15 33 13 1500 65 10 1000 8 81 500 3 23 7 15 89 56 31 13 6 19 Growth in Native AIDS cases 1984 - 2006 4000 0 Data Collection Concerns CDC surveillance reports are based on state data 7 states do not collect data on Natives! Tribes do no report to IHS Neither tribes or IHS report data to states Other Areas Of Concern Problems with collection of data Frequent misclassification of ethnicity Inclusion of community leaders in HIV/AIDS dialogues HIV diagnosis is often made late in the progression of the disease Native Risk Factors Biological Economic Social Behavioral Biological Risk Factors Sexually Transmitted Infections are: ~ a Strong indicator of high risk behavior ~ a Key factor in the transmission of HIV ~ Appear to intensify by economic hardship Economic Risk Factors POVERTY/ECONOMIC HARDSHIP Can PREVENT or INHIBIT Obtaining health education Accessing good health care Utilizing proper medical treatment If impoverished, results can be Poor health Poor diet Related diseases Diseases Associated With Poverty DIABETES Diabetes rates are high among Natives Diabetic death rates for Natives are 3.3 times the rate for other races Diseases Of Poverty TUBERCULOSIS High rates of tuberculosis are found among Native people (rates reflect 22 times higher among Natives than other races) From 1992-1994 Native death rate from tuberculosis was 475% greater than other races Social Risk Factors Homophobia Stigma Mistrust/distrust of provider system Denial Confidentiality Behavioral Risks Alcohol Abuse Plays a critical role in the AIDS epidemic Decreases inhibitions Alters perceptions Interferes with the body’s use of ~ vitamins and minerals that are ~ critical to maintain a healthy ~ immune system Behavioral Risks Injection Drug Use Reported as the source of 28% of all Native AIDS cases among women Drug use results in high-risk behaviors such as unprotected sex and sharing of needles High risk heterosexual contact Reported as the source of 44% of all Native AIDS cases among women Multiple sex partner increase risk among Native women Where Do We Begin?
