CHAPTER 25 STD’S
STD’S STI’S
Sexually transmitted disease or sexually
transmitted infections- are infectious diseases
spread from person to person through sexual
contact.
 Epidemic- occurrences
of diseases in which
many people in the same
place at the same time
are infected.

STATISTICS

65 million people in USA are infected with STD’s
Why do people go undiagnosed and untreated?
1. Many people with STD’s are without symptoms.
 Asymptomatic- without any symptoms of a
disease.
2. They fail to report STD’s to
the health department.
3. Embarrassment
HIGH RISK BEHAVIOR
10,000 teens are infected with a STD daily.
WHY?
1) Being sexually active with more than one
partner.
2) Engaging in either unprotected or
protected sex.
3) Selecting high risk partners.
4) Using alcohol and other drugs.

CONSEQUENCES OF STD’S
1. Some STD’s are incurable!!!
 Virus
 Bacteria
 Protozoan
 Lice
2. Some STD’s cause cancer.
 Hepatitis B causes cancer
of the liver.
 HPV causes cervical cancer.
CONSEQUENCES OF STD CONT:

Some STD’s can cause complications that affect
the ability to reproduce

Females can develop pelvic inflammatory
disease (PID) which damages reproductive
organs and can cause sterility.
4. Some STD’s can be passed from an infected
female to her child before, during, or after birth.
A. STD’s can damage the bones, nervous
system, and brain of a fetus
B. Premature births can result, and
infants infected with STD’s at delivery may
become blind or develop pneumonia and
some may die

WAYS TO AVOID STD’S
Abstinence- the deliberate decision to avoid
harmful behaviors, including sexual activity
before marriage and the use of tobacco, alcohol,
and other drugs.
1. Sexual activity is the
cause-----STD’s are the
effect/result.
2. Use refusal skills to
avoid situations in
which you may be at risk.

STD’S/ VIRUS

1.
2.
Human Papilloma Virus (HPV)- is a virus
that can cause gentile warts or be asymptomatic.
Most common STD in USA. 50-75% of sexually
active citizens acquire HPV at some time
throughout their lives. There are 30 different
types of HPV.
Pap test determines HPV infection.
HPV CONTINUED
3. HPV can cause Cervical Cancer, cancer of the
penis, and anus.
GENITAL WARTS
Genital Warts- are reddish or pink warts with
cauliflower tops that appear on the genitals,
vagina, or the cervix one to three months after
the infection from HPV.
 Genital Warts are highly infectious and is spread
from person to person through contact.

GENITAL WARTS
GENITAL WARTS
GENITAL WARTS
3 months for infection to appear.
 Infants born to families infected with HPV may
develop warts in their throats, obstructing the
breathing passage.
 Removal is possible, but Wart will reappear.

CHLAMYDIA
Chlamydia- is a bacterial infection that affects
the reproductive organs of both males and
females.
1. 40% of cases reported in teens 15-19 years
old.
2. Mostly asymptomatic
3. Males- might have discharge from penis
and pain during urination.

CHLAMYDIA MEN
CHLAMYDIA WOMEN
Females- signs and symptoms include:
1. vaginal discharge
2. painful urination
3. abdominal pain
A. When Chlamydia is left untreated it can
cause infertility in males and females, PID, and
premature births.
B. Antibiotics can cure Chlamydia

CHLAMYDIA WOMEN
GENITAL HERPES
Genital herpes- is an STD caused by the herpes
simplex virus.
There are two types of the herpes virus:
1. Herpes simplex 1- can cause cold sores, fever
blisters in, or around the mouth.
2. Herpes simplex 2- can cause blister like sores
on, in, or around the vagina, penis, and anus.

GENITAL HERPES
A. Genital herpes can be asymptomatic, but
blister like sores develop on genitals.
B. The virus can spread without symptoms.
C. Medication can relieve symptoms but not
cure the virus.
D.Valtrex helps dry up blister like sores.
HERPES SIMPLEX 1
HERPES SIMPLEX 2
GENITAL HERPES
GONORRHEA

1.
2.
Gonorrhea- is a bacterial STD that usually
affects the mucous membranes.
Symptoms for males, Gonorrhea have penile
discharge and pain during urination.
Symptoms for females, Gonorrhea causes
vaginal discharge, pain during urination, and
puss-like sores inside the vagina.
GONORRHEA
GONORRHEA FEMALE
GONORRHEA
3. The bacteria can spread to the bloodstream and
cause permanent damage to the joints.
4. In infants, Gonorrhea can cause blindness.
TRICHOMONIASIS
Trichomoniasis- is an STD caused by a
microscopic protozoan that results in infections of
the vagina, urethra, and bladder.
 Females signs and symptoms include, limited
symptoms with a development of vaginitis.
 Vaginitis- an inflammation of the vagina
characterized by greenish frothy discharge, odor,
irritation, and itching.

TRICHOMONIASIS
TRICHOMONOIASIS
Males signs and symptoms include- itching,
discharge, and painful urination.
 Use of Antibiotics to cure.

SYPHILIS
SYPHILIS
Syphilis- is an STD that attacks many parts of
the body and is caused by a small bacterium.
Napoleon, Caesar, Cleopatra, and Henry VIII.
1. Syphilis begins with the development of a
CHANCRE sore (Painless reddish sore at site
of infection).

SYPHILIS
SYPHILIS
1. Syphilis progresses into three different stages.
Stage 1 Chancre
Stage 2 asymptomatic symptomatic
Stage 3 latent stage.
2. If left untreated syphilis spreads throughout the
body damaging internal organs, causing paralysis,
convulsions, blindness, and heart disease.
3. Can be cured by Antibiotics
DID COLUMBUS BRING SYPHILIS TO
EUROPE?
Apparently, the New World isn't all that intrepid
explorer Christopher Columbus discovered; seems
we may also have him to thank for spreading the
pathogen that causes syphilis—along with news of
the Americas—to Europe.
 A new study provides what scientists say is the
most convincing evidence to date that the Italian
adventurer and some of his crew contracted the
disease during their voyage to the New World—
and unwittingly introduced it to the old one circa
1493.

HEPATITIS B/C
1. Hepatitis- B- is a viral infection spread
through bodily fluids. 90% of victims are
asymptomatic. S@S include nausea, vomiting,
jaundice, cancer of the liver (No CURE).
2. Hepatitis C- is a blood-borne infection that
damages the liver with no treatment and no
symptoms (Shorter life span).
PUBIC LICE

Pubic Lice- (often called "crabs" because of
their crab-like appearance under a
microscope) are six-legged creatures that
most commonly infest hair in the pubic
area. In most cases, pubic lice are
transmitted sexually from the pubic hair of
one person to another. But lice can be
contracted in other ways, too — from
infested clothing, towels, and bedding.
SEEKING TREATMENT
1. Health Department- free STD screening.
2. Any licensed Doctor
3. Your Responsibility- notify any sex partner.

HIV/AIDS
Acquired Immune Deficiency Syndrome- a
disease in which the immune system of the
patient is weakened.
 AIDS is the leading cause of death among the 2544 year age group.
 Human Immunodeficiency Virus- a virus that
attacks the immune system.

AIDS/HIV
1. HIV attacks the helper T-Cells
2. Helper T-Cells recognize any foreign
pathogen in the body and alert the whole
immune system.
 Destruction of T-Cells systematically destroys the
immune system.
 Opportunistic Disease- infections that occur in
individuals who do not have a healthy immune
system.
 HIV infection is progressive—1-12years.
TRANSMISSION
1. Sexual Intercourse/ Anal Sex
2. Sharing Needles
3. Mother to Baby
4. Infected blood product

STAGES OF HIV/AIDS
There are 3 Stages to HIV/AIDS
Stage 1:Infectious Stage- immediately after
contracting virus (3-6weeks): fever, rash headache,
body aches, and swollen glands.
Stage 2: Asymptomatic Stage- a period of time
during which a person infected with HIV has no
symptoms, 6-10 years.
Stage 3: Symptomatic Stage- the stage in which
a person infected with HIV has symptoms as a
result of immune deficiency. AIDS begins, S@S
include: swollen glands, weight loss, and yeast
infections.
DETECTING HIV
EIA- a test that screens of the HIV antibodies in
the blood.
A. Developing antibodies take 1 month to
develop
B. Certain health conditions mask
antibodies.
Western Blot- is the most common confirmation
test for HIV.
Treatments of HIV: $51,000 per month.

HIV/AIDS
HIV is resistance to the AIDS drug cocktail.
 Pandemic- a global outbreak of infectious
disease.
1. 2002- 30 million people worldwide were infected
with HIV

HIV/AIDS
1. Obtain current HIV/Aids info from state health
organization, CDC, and new media.
2. Abstinence only way to avoid contact with
HIV
3. Remember decisions today affect the rest of your
life.
A. Avoid certain situations
B. Refusal skills
C. Choose relationships carefully.
