1 The HIV/AIDS Epidemic © 2005 John B. Pryor Illinois State University

2 AIDS -  Acquired  Immune  Deficiency  Syndrome HIV -  Human  Immunodeficiency  Virus

3 Ways HIV is Transmitted: 1) through unprotected sexual intercourse 2) through sharing needles 3) through exposure to contaminated blood 4) perinatal exposure 5) mother’s milk

4 Ways you cannot transmit HIV: 1) mosquito bites 2) casual contact 3) toilet seats 4) sharing food

5 Can I get HIV from oral sex?  CDC says “yes.”  Not as dangerous as vaginal sex or anal sex  Actual risk level is unknown  Oral sex is more dangerous if the person performing it has bleeding gums or cuts/abrasions in the mouth.  Oral sex is more dangerous if the person who receives it has cuts, abrasions, or sores in the genital area.

6 Natural History of HIV/AIDS HIVInfection 3-6 Weeks AcuteHIVSyndrome 6 Months Positive HIV Test 9.8 Years 14.8 Years ClinicalAIDS Death May be extended by new drug therapies

7 Advances in HIV-Testing  OraQuick Rapid HIV Test  A swab of the outer gums, upper and lower - collects oral fluid  Test takes 20 minutes  Accuracy - Correctly identified 99.3% of people who were infected with HIV (sensitivity) and 99.8 % of people who were not infected with HIV (specificity)

8 HIV/AIDS Trends in the USA

9 History of the Epidemic 1981 – 121 deaths – A disease was identified among men who have sex with men. It was first called “gay cancer” and later named Gay Related Immuno Deficiency (GRID) 1982 – 447 deaths – Institut Pasteur in France discovered Human Immunodeficiency Virus (HIV) the virus that causes Acquired Immunodeficiency Syndrome (AIDS). CDC in US announced that HIV can be spread through sexual contact or exposure to contaminated blood. 1983 – 1,476 deaths – CDC documented transmission of HIV from heterosexual contact. American Red Cross warned `high risk donors not to donate blood

21 Why is the prevalence of HIV/AIDS higher in African Americans?  POVERTY – Almost 1 in 4 African Americans live in poverty. Research by CDC shows that poverty is a strong predictor of HIV infection.  IMPRISONMENT OF BLACK MALES – Black men are more than 6 times more likely than White men to have served in prison. 1 out of every 7 Black men 25-29 is in prison. Prison is a place where there are high risks for HIV infection: male- to-male unprotected sex, IV drug use, & prison tattoos. Black men are no more likely to perform risky behaviors than White men while in prison. They are just more likely to be there. When they get out they spread HIV to their communities.  POVERTY also predicts IMPRISONMENT.
