REDUCING YOUR RISK!!
STIs
• Sexually Transmitted Infections –
are infectious diseases spread from person to
person through sexual contact.
• A person can have an infection and pass it on to others
with out actually knowing they have the disease.
STIs are caused by pathogens (a disease causing
agent; bacteria or virus)
Spread of Pathogens
1. People (kissing,
shaking hands, sex
etc.)
2. Blood (transfusions,
open wound/ulcers)
3. Air (coughing,
sneezing)
4. Objects (needles,
combs, glasses)
5. Animals (bites,
petting)
6. Food & water

Immune System and Your Body
Interior Defense
Lymphocytes (type of white
blood cells)
2 Types –
1. Helper T Cells – signal
B cells
2. B Cells – makes infection
susceptible to
macrophages (killer
cells)
Check for Understanding
• Situation: You and your friends decide to go to a
tattoo parlor to get a tattoo.
• Explain how it is possible for you to contract a STI
pathogen.
STI Pathogens
1. Bacteria
- 1,000 types
- release toxins
2. Virus
- smallest pathogen
- invades cell
*As a general rule in regards to STI’s –
Bacteria = cure
Virus = no cure
Risky Behaviors are actions that can lead to
the contraction of STIs
• Sex with more than one person
• Unprotected sex
• Having high risk partners (partners that are sexually active
with multiple people)
• Using alcohol or other drugs – How might this
increase your chances of contracting an STI?
What are the two types of pathogens that
cause a STI?
Chlamydia
*#1 STD in America
Cause: bacteria affecting
reproductive organs of
both males and females
Symptoms: – asymptomatic:
no visible symptoms in
75% of cases
Discharge (white)burning
during urination
Complications: sterility and
PID in females
Treatment: antibiotic
Cure: Yes
Syphilis
Cause: bacteria
Symptoms: Stage 1: develop
small painless ulcerations
formed from infection called
a chancre sore
Stage 2: Skin Rash
Stage 3: Latent period,
symptoms disappear organ
damage begins
Stage 4: 10-30 years later major
complications
Complications: brain damage,
paralysis, death
Treatment: penicillin in early
stages
Cure: Yes
Genital Warts/HPV
*An estimated 75% of sexually
active people carry this
Cause: Human Papillomavirus
Symptoms: Warts appear;
asymptomatic, most don’t
develop any symptoms and it
goes unrecognized.
Complications: Can lead to
cancers, mainly cervical
cancer
Treatment: laser warts,
antibiotics to reduce
outbreaks
Cure: No
Herpes
Cause: simplex virus (Type 1 –
cold sores, Type 2 – genital
sores)
Symptoms: Sores may appear
after 2 weeks. May be
asymptomatic or have flu-like
symptoms
Complications: painful outbreaks,
possible transmission the baby,
and more susceptible to HIV
Treatment: antibiotics to reduce
outbreaks
Cure: NO
Gonorrhea
Cause: bacteria - attacks mucus membranes
Symptoms:
males- discharge yellow or white / burning during
testicle
Female- yellow discharge / burning during urination
Treatment: antibiotics
Complications:
PID
Males infertility
Late - Both spreads to bloodstream can hurt
joints, hrt valve, and brain
urination. Swollen
Pubic Lice
Cause: crab lice invade pubic hair
TOILET SEAT, SHEETS 24 hours
Symptoms: itching
PUBIC LICE
Treatment: OTC shampoo to get rid of lice HEAD
Complications: discomfort
LICE
HIV & AIDS
HIV- Human Immunodeficiency
Virus- virus destroys body’s T-Cells
(destroys immune system)
AIDS- Acquired Immune Deficiency
Syndrome-
HIV turns into AIDS when
• 200 or fewer T-cells
• Person gets opportunistic infection
Opportunistic infection- infection
that develops in a person w/ weak
immune system
HIV Infected T-Cells
How HIV Transmitted
•
•
•
•
Blood
Semen
Vaginal secretions
Breast milk
Risk Behavior
- Unprotected sex
- Sharing needles
- Blood transfusion (organs)
- Fluids in open wounds
- May pass from mother to baby

How HIV NOT transmitted
Any other casual contact
Hugging
Shaking hands
Insects
Coughing
Donating blood
World Aids Day
HIV tests
EIA- 1st test given screens for HIV
antibodies in blood
Two Positive Results
Western Blot – confirms
EIA test –
Get Western Blot Test
detects HIV antibodies
Positive Result – HIV Antibodies in blood
Negative result – no HIV antibodies
* Does not mean not infected can take up to 6 months for
antibodies to show up
3-2-1 Summarizer
• 3- Name 3 examples
of Risky behaviors
• 2- Give 2 differences
between viral and
bacterial STI’s
• 1- Write 1 STI and
give a fact or
symptom of that STI
