  2. What is AIDS? • The disease caused when the human immunodeficiency virus (HIV) enters the human white blood cells, destroys the cells and cripples the immune system Normal white blood cell White blood cell attacked by the HIV virus http://es.houstonisd.org/riveroakses/Exhibition/AIDS%202/AIDS%20Awareness/Web_files/image048.jpg http://images.encarta.msn.com/xrefmedia/sharemed/targets/images/pho/35a5c/35A5C297.jpg

  3. Causes • When the HIV virus reproduces in the white blood cells in the human body, AIDS is then produced when the virus has reduced the T4 or CD4 cell count to less than 200 • Which means your immune system is destroyed • This can be transmitted when the following contains HIV…. • Blood to blood transmission • Sexual fluids are transmitted • Breast milk • Any instrument that punctures the skin (eg. needles)

  4. History • In 1981 AIDS was first reported and was mostly common in homosexual men • Scientists in San Francisco and in New York found that people who were affected had rare skin cancers and rare type of pneumonia and tests seemed to indicate that the immune system was being destroyed • It is believed that in the 1600’s the HIV virus was transmitted from chimpanzees to humans most likely from blood transmission from hunting • The first actual confirmed death of AIDS was found in 1959 by a man in Congo, Africa

  5. Signs and Symptoms • Night Sweats • Unexplained weight loss • Nausea • Great Fatigue • Swollen Lymph nodes • Fever http://www.articles-weightloss.com/img/weight-loss-scale.gif http://tell.fll.purdue.edu/JapanProj/FLClipart/Adjectives/sleepy.gif http://tell.fll.purdue.edu/JapanProj/FLClipart/Verbs/fever.gif

  6. Diagnosis • A physician would take blood tests to tell whether the person’s immune system is making antibodies (a protein that used by the immune system to identify and neutralize foreign objects like bacteria and viruses) • If the HIV antibodies are present then the patient is HIV positive • The physician will then take more blood tests to find the patient’s CD4 count (tells how many T4 cells declines the white blood cells in which the virus produces) if they are less than 200 then the patient has AIDS • As the HIV virus progresses the number of T4 cells declines • Physician will also test blood to determine how fast the infection is progressing T4 Cell http://www.biologyreference.com/images/biol_01_img0042.jpg

  7. Treatment/Prevention • Anti-HIV medications are used to control the reproduction of the HIV virus and to slow down the progression • Highly Active Antiretroviral Therapy (HAART) combines three or more anti-HIV medications daily • These anti-HIV medications do not cure HIV and they do not cure the spread of HIV • A drug called Nevirapine was approved by the FDA in 1996, Nevirapine was proven to significantly reduce mother-to-child transmission of the HIV virus when given to pregnant mothers and children shortly after birth • Do not have sexual contact with anyone who has AIDS or the signs of AIDS avoid having sex with anyone who has multiple and/or anonymous sexual partners, avoid anal sex • Do not share needles or syringes • Exercise caution regarding procedures, such as acupuncture, tattooing, ear piercing, etc., in which needles or other non sterile instruments may be used repeatedly to pierce the skin

  8. Now Open your Envelopes… • USE THESE IF YOU ARE SEXUALLY ACTIVE!!!

  9. Future Outlook • Number of drugs like Nevirapine are being researched • The National AIDS Program of Brazil has successfully offered universal access to treatment • Top scientists from around the world are committed to vaccine development • There are also many fundraisers or AIDS awareness programs that help support AIDS victims and help to raise money to find a cure for AIDS http://direland.typepad.com/direland/images/aids_ribbon_blwh_hands.jpg http://z.about.com/d/webclipart/1/0/B/Z/aids7.gif

  10. Other Interesting Facts • When a person is tested positive for HIV they may not have AIDS for a couple of months to a couple of years • In 2000 36.1 million people were living with HIV or AIDS • 34.7 million adults had HIV or AIDS • 1.4 million people under the age of 15 had HIV or AIDS • 21.8 million people died of AIDS • HIV is not transmitted through saliva, urine, tears, mosquito, flea or tick bites • The HIV virus dies very quickly once exposed to light, heat or air http://z.about.com/d/webclipart/1/0/B/Z/aids7.gif
