  16. Chlamydia • The CDC estimates that more than 2.8 million new cases of chlamydia infection occur each year. • Chlamydia is a common cause of Nongonococcal Urethritis and, if untreated, can lead to PID (Pelvic Inflammatory Disease) in females.

  17. Symptoms of Chlamydia • Males: • 1.) Pain and burning during urination • 2.) Unusual discharge • Females (not always obvious) • 1.) Pain in the pelvic region • 2.) Painful urination • 3.) Unusual discharge • *** Can lead to Pelvic Inflammatory Disease (PID)

  18. Treatment of Chlamydia • Certain antibiotics can cure chlamydia.

Abdominal pain or tenderness

  20. Treatment of Gonorrhea • Can be treated by antibiotics.

  21. Trichomoniasis • Trichomoniasis is caused by the single-celled protozoan parasite, Trichomonas vaginalis. The vagina is the most common site of infection in women, and the urethra (urine canal) is the most common site of infection in men.The parasite is sexually transmitted through penis-to-vagina intercourse or vulva-to-vulva (the genital area outside the vagina) contact with an infected partner. Women can acquire the disease from infected men or women, but men usually contract it only from infected women.

  22. Trichomoniasis, cont. • Symptoms • Males • 1.) Itching of the penis • 2.) A clear discharge • 3.) Pain during urination • Females • 1.) Burning and itching in the vagina • 2.) Pain during urination • 3.) Yellowish-green discharge

  23. Treatment of Trichomoniasis • Can be cured with medicine prescribed by a physician. • **Trichomoniasis can cause a secondary infection in females called vaginitis.

  24. Genital Warts • Caused by a virus called Human Papilloma Virus (HPV) • Once infected, a person has the virus for the rest of her or his life. • Warts appear on the genitals one to three months after infection.

  25. Treatment of Genital Warts • Doctor may remove warts, but they may reappear. • Prescription skin medication • ** This STD may cause cervical cancer in women.

  26. Genital Herpes • Caused by Herpes Simplex Type 2 • Cannot be cured • Sores usually appear two to twenty days after contact with an infected person and may last as long as three weeks. • Other symptoms include fever and burning during urination

  27. Treatment of Genital Herpes • Breakouts may be caused by stress • Medications are used to treat the symptoms. • To avoid spreading herpes, infected persons should avoid sexual contact when blisters are present and right after they disappear.

  28. Syphilis • When left untreated, can damage vital organs, such as the heart, liver, kidneys, central nervous system including the brain. • Syphilis develops in stages. • Symptoms appear and then go away on their own. • If treated early, the disease can be cured.

  29. Stages of Syphilis • 1.) Primary Stage • Chancre • Painless, reddish sore • Appears 10 to 90 days after contact • Lasts one to five weeks and will then go away • 2.) Secondary Stage • If not treated, appears one to six months after contact • Highly contagious at this stage

  30. Stages, cont. • Non-itching rash on the chest, backs of the arms, and legs • Fever • Sore throat • General sick feeling • Without treatment, these symptoms will disappear, but the disease continues to develop.

  31. Stages, cont. • 3.) Latent Stage • Begins two or more years after infection • All signs disappear, leading the individual to believe that he or she is cured. • In this stage, the disease begins to attack the heart , blood vessels, and central nervous system. • May relapse to the second stage and develop sores again.

  32. Stages, cont. • 4.) Neurosyphilis Stage • If left untreated, the disease moves into this stage within 10 to 30 years, and the heart, skin, brain, and spinal cord are affected. • Syphilis in this stage can be treated, but not cured.

  33. Treatment of Syphilis • Blood tests determine if a person has syphilis • Penicillin is the main drug used in the treatment of syphilis • Early treatment is crucial
