Every year in the United States, more than 15 million people will catch a sexually transmitted disease (STD). People under age 25 are most likely to get an STD. Untreated STDs put women at risk of infertility (not being able to have children), continuing pain, and serious pregnancy problems.

Three Major STDs

The three most common sexually transmitted diseases in the United States are…

  1. chlamydia (cla-mid-ee-a),
  2. human papillomavirus (pap-ill-o-ma-vie-russ), and
  3. trichomoniasis (trick-o-mo-nigh-uh-sis).

Chlamydia is the most common STD caused by bacteria. About 3 million cases are diagnosed each year, mainly among teens and young adults. In women, untreated chlamydia can lead to other serious health problems, including pelvic inflammatory disease (an infection of the fallopian tubes). Most women with chlamydia have few or no symptoms. Without testing and treatment, the disease can continue for months or years. Symptoms of chlamydia, if they occur, can include unexpected discharge or bleeding from the vagina, a burning feeling when you urinate (pee), and pain in the lower abdomen. Chlamydia rates are rising fast in the U.S., especially among women, partly because of better testing. Chlamydia can be treated with antibiotics.


Human papillomavirus (HPV) is probably the most common STD among young, sexually active people. HPV is caused by a virus. About 5.5 million Americans become infected with HPV each year. HPV sometimes causes genital warts, but in many cases, people with HPV have no symptoms they can see or feel. HPV is the most common cause of an abnormal Pap smear (a test to check the health of a woman's cervix). Concern about HPV has grown in recent years because infection with certain types of HPV can lead to cancer of the cervix. Cervical cancer causes 4,500 deaths among women each year. HPV cannot be cured, but a number of different treatments can remove the warts. Changes in the cervix that may lead to cancer can be detected with a Pap smear and treated. Occasionally HPV may disappear on its own.


Trichomoniasis, often call Trich (pronounced "trick") for short, is a common infection. It is caused by a tiny, one-celled organism, called a protozoan. As many as 5 million cases occur each year in the United States. In women, trich can cause vaginal itching, redness, and a frothy, yellow-green discharge. The infection may also cause pain or discomfort during sexual intercourse or urination. Trichomoniasis may increase the risk of infection with human immunodeficiency virus (HIV), the virus that causes AIDS. Trich usually can be cured with an antibiotic.


Testing

Screening tests can help determine if you have an STD. If you are young and have had or are having sex, have a new or multiple sex partners, and don't use condoms EVERY time or properly - you are at risk. If you think you could have an STD, tell your doctor or call your local health department. STD testing usually is not done as part of a regular exam or visit to the gynecologist. Be sure to discuss any concerns with your healthcare provider. He or she can help decide which STD tests are right for you.


Prevention

If you are sexually active, stay with one partner who you know does not have any STDs and is not having sex with anyone else. Having more than one sexual partner, or having sex with someone who has other partners, greatly increases your risk of getting infected.

When used correctly with every act of intercourse, male latex condoms are good for preventing many STDs. If you are sexually active or plan to be, ask your doctor for instructions about correct condom use, or call or visit the websites of the organizations listed below.
