1. HIV/AIDS

2. HIV Human Immunodeficiency Virus: The virus that ends up as AIDS
HIV attacks the immune system, which makes it difficult for the immune system to defend the body against infections
Infections that would be harmless to a healthy person can be fatal to a person with HIV

3. AIDS Acquired Immunodeficiency Syndrome: Final phase of the HIV virus
Classified as a STD, but can be spread in other ways
sharing infected equipment for injecting drugs, tattooing, or ear piercing

4. HIV facts
1st cases were diagnosed in U.S. in 1981 in N.Y. & S.F. = 379 reported cases
10 years later = more than 200,000 cases
End of 1995 = over 500,000 cases
Many of the initial cases were in homosexual men, many people believed only homosexuals can get it = FALSE!!!!!
Anyone who engages in risky behaviors can become infected with HIV

5. How it enters the body (pg 670)
Virus must find away into the bloodstream
Can spread through contact with infected blood
Sharing drug needles, syringes & tattoo equipment that’s not properly maintained
Sexual contact with infected person
Enters through the lining of the vagina, penis, rectum or mouth during sex.
Can be transmitted during pregnancy, birth &/or breast milk

6. Ways You Can NOT Contract HIV
casual contact
simple kiss

Vaginal Fluids
Breast Milk
Will NOT transmit the virus:
Saliva/Spit
Urine/Pee
Sweat
Tears
Vomit
Feces/Poop
Mucus/Boogers/Snot

8. How does it work? (pg 671) HIV targets white blood cells (T4)
T4 cells are important because they coordinate the defense against infections
By targeting T4 cells it destroys the immune system
Once the immune system is destroyed the body become defenseless against other viruses, bacteria, fungi & cancer cells

9. HIV/AIDS: (3 Phases) Phase 1: Infection With No Signs/ Symptoms
Possible to live many years without any signs/symptoms
Once diagnosed you are “HIV-positive”

11. HIV/AIDS: (3 Phases) Phase 3: “AIDS”
Official criteria for diagnosing AIDS:
Have fewer than 200 T4 cells p/cubic millimeter of blood. (Healthy adults = 1,000 +)
AND
presence of an opportunistic infection(s)

12. HIV/AIDS: (3 Phases)
Opportunistic infections generally don’t affect healthy people in a sever manner
Symptoms of opportunistic infections: Fever, Vision loss, Coughing & shortness of breath, Seizures & lack of coordination, Difficult or painful swallowing, Pneumonia & coma
