Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Sexually Transmitted Diseases • Have reached epidemic proportions in the U.S. • 25% of all Americans will acquire at least one sexually transmitted disease (STD) in their lifetime • Each year, more than 19 million people in the U.S. are newly infected with STDs • Each year more than 19 million Americans are newly infected with an STD • The highest rate of STD infections are seen in young people between the ages of 15 and 24 • Worldwide, 1 million people are infected daily with STDs not including HIV
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Chlamydia • Caused by a bacterial infection that spreads • During vaginal, anal, or oral sex • From the vagina to a newborn baby during childbirth • Can cause serious damage to the reproductive system • Is a major factor in male and female infertility • May not produce symptoms, thus 75% of infected individuals don’t know they’re infected until the infection has become quite serious • 2.8 million new cases are reported each year in the U.S. • 15- to 19-year-old girls represent 46% of infections • 20- to 24-year-old women represent another 33%
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Chlamydia • When symptoms are present, they include abdominal pain, fever, nausea, vaginal bleeding, and arthritis • Treatment requires oral antibiotics • Damage to the reproductive system is irreversible
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Gonorrhea • Caused by a bacterial infection • Transmitted through vaginal, anal, and oral sex • Symptoms in men • Typical symptoms include a pus-like secretion from the penis and painful urination • Symptoms in women • Women also may have discharge and painful urination • Up to 80% of infected women don’t experience symptoms until the infection has become fairly serious • At this stage, women develop fever, severe abdominal pain, and pelvic inflammatory disease
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Gonorrhea • Untreated gonorrhea can produce • Infertility, widespread bacterial infection, heart damage, arthritis • Blindness in children born to infected women • Treated successfully with penicillin and other antibiotics
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Pelvic InflammatoryDisease (PID) • Not a true STD, but rather a condition resulting from complications of chlamydia or gonorrhea • Often develops when the STD spreads to the fallopian tubes, uterus, and ovaries • Each year more than 1 million women in the U.S. develop PID • Complications include scarring and obstruction of the fallopian tubes, infertility, ectopic pregnancies, and chronic pelvic pain

Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Genital Warts • Treatment requires complete removal of all warts by • Freezing them with liquid nitrogen, dissolving them with chemicals, or removing them through electrosurgery or laser surgery • Patients may have to be treated more than once, because genital warts can recur
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Genital Herpes • A common STD caused by the herpes simplex virus (HSV) • Several types of HSV produce different ailments, including • Genital herpes, oral (lip) herpes, shingles, and chicken pox • The two most common forms of HSV are Types I and II • Type I is most commonly known to cause oral herpes • Cold sores or fever blisters appear on the lips and mouth • About 135 million people over the age of 12 carry HSV Type I • HSV Type II is better known as the virus that causes genital herpes • About 45 million people over 12 are infected with HSV Type II • More than 1 million new cases are diagnosed each year
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Genital Herpes • HSV is a highly contagious virus • Victims are most contagious during an outbreak • HSV spreads by contact with an active sore • HSV can also be spread through virus-containing secretions from the vagina or penis
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Genital Herpes • A few days following infection, sores may appear on the infected areas (mouth, genitals, rectum) but may also surface on other parts of the body • Victims usually have mild fever, swollen glands, and headaches • Symptoms usually disappear within a few weeks, causing some people to believe they are cured • Herpes is presently incurable; its victims do remain infected • The virus can remain dormant for extended periods, but repeated outbreaks are common
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Herpes Virus • Both HSV Type I and II can cause oral and genital sores • People who have an outbreak of oral herpes should not touch their genitals or someone else’s after touching the oral cold sores (doing so can lead to herpes infection of the genitals) • Oral sex can also cause transmission of the HSV from the lips to the genitals and vice versa • People with cold sores on the lips or mouth should exercise care not to touch these sores • Hands should be carefully washed with soap following contact with cold or herpes sores
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Syphilis • Caused by a bacterial infection • 3 weeks after infection, a painless sore appears where the bacteria entered the body • The sore disappears on its own in a few weeks • If untreated, additional sores may appear within 6 months of initial outbreak but will also disappear by themselves • A latent stage during which victim is not contagious may last up to 30 years (victims think they are healed)
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Syphilis • During the final stage • People may develop paralysis, crippling, blindness, heart disease, brain damage, insanity • Some infected people die from the disease • Penicillin and other antibiotics are used in its treatment
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Critical Thinking • Many individuals who have sexually transmitted diseases withhold this information from potential sexual partners. Do you think that it should be considered a criminal action if such an individual knowingly transmits a STD to someone else?
Acquired immunodeficiency syndrome (AIDS): Any of a number of diseases that arise when the body’s immune system is compromised by HIV Human immunodeficiency virus (HIV): Virus that leads to acquired immunodeficiency syndrome (AIDS) Opportunistic diseases: Diseases that arise in the absence of a healthy immune system, which would fight them off in healthy people Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV Key Terms
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV HIV & AIDS • Upon infection, the HIV virus multiplies, attacks, and destroys white blood cells • White blood cells are part of the immune system that fights infections and diseases • As the number of white blood cells killed increases, the body’s immune system gradually breaks down or may be completely destroyed • Without the immune system, a person becomes susceptible to various opportunistic diseases and cancers • HIV infection is determined through an HIV antibody test
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV HIV & AIDS • HIV is a progressive disease • At first, people who become infected with HIV might not know they are infected • An incubation period of weeks, months, or years may pass during which no symptoms appear • The virus may live in the body 10 years or longer before symptoms emerge
Chlamydia Gonorrhea Pelvic Inflammatory Disease Human Papillomavirus and Genital Warts Genital Herpes Syphilis HIV and AIDS Reducing the Risks for STDs Reducing the Risks for HIV HIV & AIDS • As the infection progresses to the point at which certain diseases develop, the person is said to have AIDS • HIV itself doesn’t kill, nor do people die of AIDS • AIDS is the term designating the final stage of HIV infection • Death is caused by a weakened immune system that is unable to fight off opportunistic diseases
