Lesson 2 Common STIs Why is it necessary for you to be informed about sexually transmitted diseases or infections? Learning about STDs can help you avoid the behaviors that lead to infection. Lesson 2 Lesson Objectives In this lesson, you’ll learn to: Identify symptoms and treatments for some common STDs. Identify community health services for getting help with prevention and treatment of STDs. Analyze the influence of public health policies and practices on the prevention and treatment of STDs. Analyze the harmful effects of STDs on the developing fetus. Lesson 2 Common STIs Some STDs Prevalent in the United States Human Papillomavirus (HPV) Chlamydia Genital Herpes Gonorrhea Trichomoniasis Syphilis Lesson 2 Human Papillomavirus An Epidemic of STDs in the United States The human papillomavirus (HPV), is considered the most common STD in the United States. About 30 different types of HPV can infect the genital area. Most types of HPV infections are asymptomatic. A Pap test and other medical examinations may detect changes associated with HPV. Almost all cases of cervical cancer are caused by certain types of HPV. Lesson 2 Human Papillomavirus Genital Warts Genital warts are pink or reddish warts with cauliflowerlike tops that appear on the genitals, the vagina, or the cervix one to three months after infection from HPV. Diagnosis is determined by a health care worker by examination of the warts. Treatments can rid the body of the warts but not the virus. Infants born to females infected with HPV may develop warts in their throats, obstructing the breathing passages, which can be life-threatening. Lesson 2 Chlamydia What Is Chlamydia? Chlamydia is asymptomatic in 75 percent of infected females and 50 percent of infected males. Chlamydia is diagnosed by laboratory examination of secretions from the cervix and the urethra. It can be treated with antibiotics, but no immunity develops, so a person can become infected again. Chlamydia can cause premature birth, and infants born to infected females may develop eye disease or pneumonia. Lesson 2 Genital Herpes What Is Genital Herpes? Most individuals who have genital herpes are asymptomatic. Those who do show symptoms typically have blisterlike sores in the genital area that occur periodically. Diagnosis is made through laboratory tests on the fluid from the blisters. Medication can relieve the symptoms but cannot cure herpes infection. The herpes virus is potentially fatal for infants who contract the virus from their mothers at the time of delivery. Lesson 2 Gonorrhea What Is Gonorrhea? Symptoms of gonorrhea include a discharge and pain or burning on urination. Diagnosis in males is made by staining and examining the discharge under a microscope. Diagnosis in females is made by swabbing the cervix and growing the organisms in a laboratory. Infants born to mothers with gonorrhea can contract eye infections that cause blindness. Lesson 2 Trichomoniasis What Is Trichomoniasis? Trichomoniasis may result in vaginitis, an inflammation of the vagina characterized by discharge, odor, irritation, and itching. When symptoms do occur in males, they include mild urethral itching or discharge and burning after urination. In females, trichomoniasis is diagnosed by microscopic examination of the discharge, while males are usually treated without laboratory testing if their partners are infected. Lesson 2 Syphilis What Is Syphilis? The first sign of syphilis is a painless reddish sore called a chancre. The sore will heal on its own, but if the infection is not treated, it spreads through the blood to other parts of the body. Eventually, the disease can damage internal organs, including the heart, liver, nervous system, and kidneys. An infant infected with syphilis may have a damaged nervous system and can die from the effects. Lesson 2 Other Common STDs Lesson 2 Seeking Treatment Treating STDs Being embarrassed should not stop a person who thinks that he or she may have been exposed to an STD from visiting a private physician or a public health clinic. Only a health care professional can prescribe the correct treatment, including antibiotics, for some STDs. Lesson 2 Seeking Treatment Preventing the Spread of Infection Public health clinics sometimes help with contacting current and past partners to make sure they get any needed treatment. Ultimately, however, it is the responsibility of any person infected with an STD to notify everyone with whom he or she has had sexual contact. Informing someone else about the possibility of having an STD could save the person’s life. Lesson 2 Quick Review Provide a short answer to the question given below. Q.

Lesson 2 Quick Review Provide a suitable analysis. Public policies enable health officials to locate and contact sexual partners of people who have been diagnosed with an STD. How do these policies help with the prevention and treatment of STDs?
