 AIDS- acquired immunodeficiency
syndrome
 Acquired means you get it from someone
 final stage of HIV infection
 May take years for a person even without

have AIDS
 Know you are HIV positive?
 knowingly spread it to your partner

Risk Factors
 increase your risk for infection if:
 injected IV drugs/steroids into veins with
equipment that was shared with others
 unprotected vaginal/anal/oral sex
 multiple/anonymous partners
 exchanged sex for drugs/money
 been diagnosed or treated for
Hepatitis/STD
 blood transfusion between 1978-1985
 unprotected sex with anyone who has the
above listed risk factors
 Tattoos/piercings with unsterilized
equipment
Prevention
 abstinence until you are in a relationship
with only one person and are having sex
with only each other
 talk about HIV/STD’s with your partner
before you have sex
 use a latex condom every time you have
sex
 get tested if you have another STD
 do not inject illegal drugs
 A- Abstinence
 B- Be Faithful
 C- Condoms
Diagnosis
 only way to know if you have been infected
is to be tested
 have to be tested when applying for a
marriage license-only way to keep track
 can not rely on symptoms because some
people do not have symptoms for many
years
 takes 3 weeks to 2 months before your
body shows antibodies for HIV-some people
can take even longer

3 Stages (Early/Middle/Late)
Early Stage
fever
Headache
Flu-like symptoms

lack of energy
weight loss
frequent fever and sweats
frequent yeast infections
skin rashes
flaky skin
PID in females
short term memory loss
Testing
 Home test kits
 EIA/ELISA tests are blood tests99.5% accurate
 positive test is followed with a second
test called the Western Blot Test to
confirm
 When all test are done there is a 99.9
% accuracy
 Most HIV tests look for antibodies in
the blood
Why hasn’t a vaccine been
developed?
 An HIV vaccine continues to elude
researchers
Opportunistic Diseases
 most common ones:
 PCP (Pneumocystis) Pneumonia- a severe lung
infection
 KS (Kaposi’s Sarcoma)- a skin cancer
 CMV- an infection of the eyes
 Candida- a fungal infection that can cause
thrush (a white film in the mouth)
 throat and vaginal infections
 serious weight loss “Wasting Syndrome”
 brain tumors
Treatment
 no cure for AIDS
 antiretroviral drugs such as AZT slow
down the virus/slow down the
damage HIV does to your immune
system
 side effects such as nausea and vomiting
 VERY EXPENSIVE
 health insurance does not want to pay
the costs
