AIDS: Case Study Acquired Immune Deficiency Syndrome
Disease • In 2009, the WHO estimated 33.4 million people with AIDS worldwide • 2.7 million new HIV infections each year
Disease • Final stage of HIV • Considered a Pandemic • Interferes with the immune system
Disease Causing Agent • Lysogenic virus
Infectious Mechanism • Transmitted through body fluids
Transmission • Mucous membranes and blood stream: • Blood • Hypodermic needles • Vaginal, oral, or anal sex • Pregnancy, childbirth, or breastfeeding
Symptoms • Immunosuppressant • Opportunistic infections • Tumors • Flu-like illness upon contraction (sometimes)
Diagnosis • Blood Testing
Treatment • Drug ‘cocktails’ • HAART • Highly active anti retroviral therapy • Expensive • Multiple side effects • Not available in all countries
Cures? • There is currently no cure for HIV or AIDS
Major Misconceptions • HIV is the same as AIDS • Sex with a virgin cures AIDS • HIV antibody testing is unreliable • HIV can be transmitted by: • Hugging • Touching • Kissing • Coughing • Sneezing • HIV positive people can be detected by their appearance
Major Misconceptions • HIV cannot be transmitted through oral sex • HIV is transmitted by mosquitoes • HIV cannot live for very long outside the body • HIV only infects homosexual men and drug users • A woman with HIV cannot have children • AIDS came from human-monkey intercourse
Historical • 60 million people infected worldwide • 25 million deaths • First reported on June 5th, 1981 • By CDC due to 5 homosexual men contracting pneumocystis pneumonia
Historical • Originally called GRID • Gay Related Immune Deficiency • 4 H Disease • Homosexual, Heroin user, Haitians, Hemophiliacs
Historical • First positive case from the Congo in 1959 • Genetic studies show it jumped from chimpanzees around 50 years earlier
Historical • Most likely entered the U.S. from Haiti
Historical • Rock Hudson • Freddie Mercury • Arthur Ashe • Magic Johnson • Isaac Asimov
Political Impact • Truly and international disease • If a country acts quickly spread can be slowed • Used to be a death sentence
Africa • Worst affected continent • 9 countries have more than 10% of adult population infected • Botswana = 24.8% • South Africa = 17.8% • ~5.6 million people have HIV • Most of any country
political • Spending • Education • Medicine and Health • Health workers • Diagnostic tests
Discussion Questions • Why is HIV considered an international disease? • Is AIDS a pandemic? Why or why not? • How does scientific education affect the spread of AIDS? • How has HIV changed with regard to lifespan over the last 60 years? • Why is Africa called a continent of orphans?
Assessment • 1. What were the major populations initially at risk of contracting HIV in the U.S.? • 2. What population is the fastest rising group that is contracting HIV? • 3. What are 3 ways that HIV can be transmitted? • 4. What region of the world is currently the most affected by HIV and AIDS? • 5. Describe one of the major symptoms of HIV or AIDS.
Assessment • 6. What do you think is the best way for the CDC and WHO to handle the current AIDS pandemic? What do you think is the best preventative technique?
