Chapter Fifteen
Sexually Transmitted Infections and
HIV/AIDS
Agenda
 Discuss Attitudes and STIs
 Review Information about Sexually
Transmitted Infections
 Discuss Human Immunodeficiency Virus
(HIV) and Acquired Immune Deficiency
Syndrome (AIDS)
 Review Cross-Cultural Aspects of AIDS
 Discuss Preventing STIs and AIDS
Introduction
 Over 65 million people in the U.S. are living
with an incurable STI
 19 million STI infections occur each year, half
to those to people 15-24 years old
 There are more than 25 infections that spread
mainly through sexual activity
Design a Campaign
 You have been chosen to develop a
campaign aimed at developing healthy
sexuality for high school students.
 In this particular city the rate of STIs is the
highest in the country.
 Develop the components of your ad
campaign.
 Present your campaign plan to class.
Self Reflection Exercise
Do NOT discuss. Write down your thoughts
privately.
If I found out I was infected with herpes or
genital warts, I would …
If my partner were infected with chlamydia,
I would …
If I found out I had AIDS, I would …
Attitudes about Sexually
Transmitted Infections
Attitudes and the STI Epidemic
 STIs have been viewed as a sign of corrupt
sexuality
 Punishment concept of disease – that a
person got what they deserved
 Negative beliefs and stigma about STIs
currently exist
These negative attitudes can interfere with
getting tested for an STI
Attitudes and the STI Epidemic
 College students believe they are immune to
STIs and engage in high-risk sexual
behaviors
e.g. multiple partners, unprotected
intercourse
 2/3 of STIs occur in people under 25
Sexually Transmitted
Infections: Trends
Reporting
Pregnancy Complications
Protection
Reporting Issues
 All states must report syphilis, gonorrhea,
chancroid, chlamydia, HIV, & AIDS cases
 Many states require that genital warts and
herpes be reported
 Women are more susceptible to gonorrhea,
chlamydia, HIV
 Women have more risk of complications from
STIs because vaginal tissue is fragile
 Women are more likely to be asymptomatic
Pregnancy Complications
 STIs can affect pregnancies
 30-40% of preterm births and infant deaths
are due to STIs
 Some can cross the placenta (syphilis, HIV)
 Some can infect the newborn during delivery
(chlamydia, gonorrhea, herpes, HIV)
 HIV can be transmitted through breastfeeding
 Antibiotics and c-sections can minimize harm
Protection
 Barrier methods can decrease the risk of STIs
 Non-oxynol 9 may increase the risk of
infection by irritating the skin
 Condoms are the most effective contraceptive
that reduces the STI risk
 Condoms cannot cover all of the penis, vulva,
or scrotum
Protection: Partner Issues
 Most effective way of avoiding STIs is to
abstain from oral, vaginal, and anal sex or be
in a long-term, mutually monogamous
relationship with someone free from STIs
 If a person does have an STI, treatment
should include treatment of their sexual
partner(s)
Class Exercise: Condom Line Up

Sexually Transmitted
Infections
Ectoparasitic Infections
Bacterial Infections
Viral Infections
Ectoparasitic Infections
 Parasites that live on the skin’s surface
 Two sexually transmitted varieties:
Pubic Lice
Scabies
Pubic Lice
 Also called “crabs”
 Small, wingless insects that are difficult to
detect on light-skinned people
 Attach to pubic hair (preferred) by their claws
& drink from tiny blood vessels under the skin
 Cannot survive more than 24 hours off of the
body, however, they reproduce rapidly and
eggs are cemented to the hair
 Highly contagious
Pubic Lice: Prevalence, Symptoms,
Treatment
 Incidence: common
 Symptoms: mild to severe itching (particularly
at night) thought to be due to allergic reaction
from their saliva
 Diagnosis: lice and eggs are visible
 Treatment: kill eggs & lice with Kwell ointment
(shampoo, cream); clothing & sheets dry
cleaned, boiled, or washed in hot water
Scabies
 Mite Sarcoptes scabiei
 Spread via any skin-to-skin contact
 Mites can live up to 48 hours off of the body
 Not visible to naked eye
Scabies: Prevalence, Symptoms, Treatment
 Incidence: millions worldwide
 Symptoms: rash and severe itching
 Diagnosis: examination of the rash and a skin
scraping can confirm diagnosis
 Typically less than 10 mites on the body
during an infection
 Treatment: topical creams; clothing and
sheets washed in hot water
Bacterial Infections
 Gonorrhea
 Syphilis
 Chlamydia and Nongonococcal Urethritis
 Chancroid
 Vaginal Infections
 Pelvic Inflammatory Disease
Gonorrhea
 Also called the “clap” or “drip”
 Survives only in mucous membranes, such as
the cervix, mouth, urethra, rectum, throat,
eyes
 Transmitted when mucous membranes
contact each other
 Incidence: second most commonly reported
infectious disease in the U.S.; 600,000 to 1
million new cases each year
Gonorrhea: Symptoms
 Women: most are asymptomatic, cervix is
most common infection site; urinary
frequency, abnormal bleeding
 Men: 25% are asymptomatic; epididymitis,
urethral discharge, painful, frequent, & urgent
urination
 Swelling, pain, & pus in the joints
 Rectal gonorrhea: bloody stools & pus
Gonorrhea: Diagnosis & Treatment
 Diagnosis: examine for bacteria in a sample
of the discharge; can also run DNA testing of
urine
 Treatment: antibiotics (oral, injection)
Note: there are rare cases when they have
become drug-resistant
Syphilis
 Live in the mucous membranes
 Typically first infects the cervix, anus, penis,
lips, or nipples
 Incidence: 7,177 cases reported in 2003
 Symptoms: 3 stages
Primary/Early
Secondary (after chancres disappear)
Tertiary (remission, but still infectious; can
lead to long term health risks)
Syphilis: Stage 1
1: primary/early syphilis 10-90 days after
infection
Chancres (small, round, red-brown,
painless sores with a hard raised edge &
sunken center) may appear on the
vulva, penis, vagina, cervix, anus,
mouth, lips
Syphilis: Stage 2
2: secondary syphilis after chancres
disappear
Syphilis invades the central nervous
system
Reddish patches on the skin, possible
wart-like growths in area of infection
Lymph glands enlarge
Headaches, fever, anorexia, flu-like
symptoms, fatigue
Syphilis: Stage 3
3: tertiary/late syphilis
Stage of remission and a person feels
fine, though able to transmit the disease
for 1 year
If not treated, this stage can cause
neurological, muscular, sensory, &
psychological difficulties and is
eventually fatal
Syphilis: Diagnosis & Treatment
 Diagnosis: culture taken from a lesion; blood
tests
 Treatment: Penicillin; antibiotics can
temporarily increase the symptoms for a few
hours
Chlamydia and Nongonococcal
Urethritis
 May also cause epididymitis and
nongonococcal urethritis in men
 Incidence: most commonly reported
infectious disease in the U.S.; estimated 2.8
million new cases per year
Highest among African Americans
Higher in young women
Underdiagnosed in men
Chlamydia and Nongonococcal
Urethritis: Symptoms
 Chlamydia is highly contagious
 Symptoms: asymptomatic in 75% of women
and 50% of men
Female symptoms: burning while urinating,
painful intercourse, pain in lower abdomen,
bleeding/spotting, rare for discharge
40% will get PID, 20% will become infertile
Male symptoms: discharge from penis,
burning while urinating, burning & itching at
penile opening, pain or swelling of testicles
Chlamydia and Nongonococcal
Urethritis: Diagnosis & Treatment
 Diagnosis: culture cervical discharge for
women, blood test, urine test for men
 Treatment: antibiotics for 7-10 days; some
cases have become drug-resistant
Vaginal Infections
 There are many common vaginal infections
related to sexual intercourse
Trichomoniasis
Bacterial vaginosis
Candiasis
Trichomoniasis
 Trichomonas vaginalis
 Female symptoms 3-28 days after infection:
increase in yellowish, frothy, & foul-smelling
vaginal discharge; burning/itching in vagina;
asymptomatic
 Male symptoms: asymptomatic, discharge at
tip of penis, burning while urinating or
ejaculating
 Treatment: metronidazole (Flagyl™)
Bacterial Vaginosis
 Most common vaginal infection in women of
childbearing age, though half are
asymptomatic
 Increased susceptibility with: multiple
partners, douching, low concentrations of
beneficial vaginal bacteria
 Treatment: metronidazole or clindamycin
Candidiasis
 Vulvovaginal candiasis; yeast infection
 Caused by a variety of fungi, most commonly
Candida albicans
 Fungi normally common in vagina, but will
multiply when the pH balance is disturbed
 pH changes due to: pregnancy, oral
contraceptives, douching, antibiotics,
diabetes, fecal material contacting the vagina
Candidiasis
 Symptoms: burning, itching, and increase in
vaginal discharge that may be thin, white, and
including white chunks
 75% of women will have at least one yeast
infection
 Recurrences are common
 Treatment: antifungal prescription or over-thecounter drugs (cream is topical or inserted
into the vagina); plain yogurt
Pelvic Inflammatory Disease
 Infection of the female genital tract
 Most often caused by chlamydia and
gonorrhea
 PID can cause long-term complications such
as ectopic pregnancies, chronic pelvic pain,
infertility
 Estimated to affect 1 out of 7 women by age
35 at least once
Pelvic Inflammatory Disease:
Symptoms & Tratment
 Characteristics of a typical PID sufferer:
young, unmarried, multiple partners, had an
STI, early age at first intercourse, minority,
use douches
 Symptoms: acute pelvic pain, high fever,
abnormal vaginal discharge
Often asymptomatic
 Treatment: antibiotics for 14 days
Viral Infections
 Once a virus enters a body, it can reproduce
and the person will have it for the rest of their
life
Although they may not experience
symptoms while the virus lies dormant,
they are still infected
 Common Viral STIs
Herpes
Human Papillomavirus
Viral Hepatitis
Herpes
 Infection with herpes simplex virus (HSV)
 The virus prefers the mouth and face (herpes
simplex I) or the genitals (herpes simplex II)
 The symptoms may be less severe if the virus
infects a less preferred site
 The virus exists in the sores, as well as from
the infected skin without the sores present
(viral shedding)
 HSV can be spread without active symptoms
 A person can reinfect themselves on another
body part
Herpes: Incidence & Symptoms
 Incidence: one of the most common STIs in
the U.S.; 1 million infected each year
 Symptoms: sores that last 8-10 days,
tingling/burning feeling, itching & red swollen
genitals, painful urination, blisters with pus,
fever, headaches, pain, itching, discharge,
fatigue
Over time, outbreak frequency diminishes
Psychological reactions: guilt, anger,
anxiety, helplessness, frustration,
depression, lowered self-esteem
Herpes: Diagnosis & Tratment
 Diagnosis: presence of blisters, sometimes a
scraping will be taken
 Treatment: no cure; therapy with antiviral
drugs (topical, oral, injected) to decrease
outbreaks, prevent complications, & reduce
viral shedding; ice pack; cooling or drying
agent; L-lysine; decrease sugar & nuts
Vaccines are undergoing trials
Human Papillomavirus
 Over 30 types of HPV
 Almost all cervical cancers can be attributed
to HPV and HPV can also cause genital warts
 Transmitted through intercourse, oral sex,
vulva-to-vulva sex, anal sex
 Incidence: estimated 50% of sexually active
people will get HPV
Related factors: intercourse before 16, 2+
sexual partners in a year, Hispanic women
Human Papillomavirus: Symptoms &
Treatment
 Symptoms: asymptomatic; genital warts in
10% of HPV cases (highly contagious); foulsmelling discharge; itching & pain
 Diagnosis: visual inspection of warts,
biopsies, Pap test
 Treatment: chemical topical solutions,
cryotherapy, electrosurgical interventions,
laser surgery
May resolve itself or need many treatments
Viral Hepatitis
 3 types & their transmission routes:
Hepatitis A (HAV) – fecal-oral contact;
vaccine-preventable
Hepatitis B (HBV) – high-risk sexual
behaviors
Hepatitis C (HCV) – sexual behavior, drug
use, unscreened blood transfusion
 Incidence:
HAV: 1/3 in the U.S.
HBV: 1.25 million in the U.S.
HCV: 3.9 million in the U.S.
Viral Hepatitis: Symptoms
 HAV: fatigue, abdominal pain, loss of
appetite, diarrhea
 HBV: asymptomatic, nausea, vomiting,
headaches, jaundice, fever, fatigue, darkened
urine, liver enlargement, chronic liver disease
 HCV: asymptomatic, mild illness, chronic liver
infection
Viral Hepatitis: Diagnosis & Treatment
 Diagnosis: blood test
 Treatment: 3 drugs that interfere with the life
cycle of the virus and induces an immune
response
Vaccines are available for HAV and HBV
Recommended for high risk individuals

Overview of HIV and AIDS
 AIDS is caused by HIV
 HIV is transmitted through bodily fluids
(semen, vaginal fluid, blood) during vaginal &
anal intercourse or by sharing needles
 The virus may remain dormant, however, it is
often fatal if untreated
 Origin of HIV is unknown
HIV and AIDS: Progression
 HIV attacks T-lymphocytes (T-helper cells) in
the blood, lowering the body’s ability to fight
infections
 Immune system releases antibodies & many
white blood cells to fight the HIV infection
 The lowered immune system response
means many opportunistic diseases infect
people with AIDS that a healthy person can
easily fight
Incidence of HIV/AIDS
 Since 1981, 1.5 million Americans have
become infected; 35-42 million worldwide
 Women are the fastest growing group in the
U.S. because vaginal tissue is more easily
damaged during intercourse, although men
drive the spread of HIV
 Can be transmitted to a baby during
pregnancy, labor & delivery, & breastfeeding
 71% of new AIDS cases are in minorities
Video: “One + One”
 Discuss your response to this video.
 What did you learn about HIV/AIDS?
Knowledge and Attitudes about AIDS
 More knowledge about AIDS in the U.S. has
not been correlated with practice of safer sex
or behavior changes
 3 unique aspects of AIDS:
Fear of transmission
Social worth of those with the disease
Incomprehensible magnitude of the
disease
 AIDS remains stigmatized in the U.S.
Symptoms
 Decline in T-helper cells takes 3 years if
depressed, and 5+ years if not depressed
 AIDS develops within 8-10 years without
treatment
 Early symptoms are flu like (fever, headaches,
fatigue, sore throat, swollen lymph nodes)
 Later symptoms: weight loss, severe diarrhea,
night sweats, oral candidiasis, gingivitis, oral
ulcers, fever, dizziness, confusion
 Opportunistic diseases: pneumonia,
toxoplasmosis, cryptococcosis, cytomegalovirus,
Kaposi’s sarcoma
Diagnosis
 Tests typically look for antibodies that fight
HIV, though some may look for HIV in blood
 Antibody tests can require 2 weeks for the
result
 Rapid tests are less effective
 False negative and false positive results are
possible with all tests
CNN Video: New HIV Testing Procedure
Treatment
 Before treatment, a viral load test and CD4+ T cell
count are taken to determine how much HIV is in the
system and to provide a baseline to assess the
effectiveness of treatment
 HAART – highly active antiretroviral therapy
Blend of 3+ HIV drugs (drug cocktails)
Can involve taking 25+ pills a day at different
times on a strict schedule
Expensive: $10,000 to $15,000 per year
Side effects: fatigue, fever, rashes, nightmares,
headaches, nausea, diarrhea, increased
cholesterol, diabetes, lowered bone density, liver
problems
Prevention
 Requires behavior change
 Many schools now include AIDS education
 HAART has been related to an increase in
high risk sexual practices in homosexual
men, but not among heterosexuals
 If infected, inform past partners that they
should be tested
 Research into high risk behaviors is needed
 First AIDS vaccine was found ineffective
Families and AIDS
 Due to the social stigma, caretakers often
have no one to turn to
 Adolescents that were told their parents had
AIDS had more emotional distress and
engaged in more high risk sexual practices
Cross-Cultural Aspects of AIDS
 95% of HIV cases lack access to treatment
 AIDS has largely affected children
 Areas throughout the world:
Asia and the Pacific
Europe and Central Asia
Sub-Saharan Africa
Latin America and the Caribbean
The Middle East and North Africa
Other Issues
Asia and the Pacific
 Over 7 million with HIV, many are young
 Rising number of infections in India & China
 China lacks an adequate supply of condoms
 3% of Cambodia is infected
 Indonesia’s rise in IV drug use adds to the
HIV epidemic
 Thailand has shown a decrease due to the
copy of antiretroviral drugs for patients and a
100% condom use program for prostitutes
Europe and Central Asia
 2 million people
 Large increase of HIV infections in the
Russian Federation, mainly because of IV
drug use
Sub-Saharan Africa
 Most of the people with HIV live in Africa
 70% of HIV-positive people live in subSaharan Africa
 Most people are not receiving HAART
therapy due to costs, and they are also not
being treated for opportunistic diseases
 Male-female power disparity is problematic
 HIV-positive men believe sex with a virgin will
cure them
Latin America and the Caribbean
 2 million adults and children
 Many countries offer free or low cost
antiretroviral therapy to those with HIV/AIDS
 They are able to reproduce the drugs that are
not patented outside of the U.S.
The Middle East and North Africa
 480,000 people
 Due to IV drug use, men having sex with
men, prostitution, low condom usage
Prevention
Preventing STIs and AIDS
 If sexually active, you should get tested
 Have partner tested if in a sexual relationship
 Carefully choose partners
 Use barrier methods, such as condoms
 Avoid high-risk sexual behaviors if not in a
monogamous relationship
 Early detection & treatment is important
 Notify your sexual partners
 Talking about STIs – honesty & trust
