It is an infection or disease passed from person to person through sexual contact.

How do you get an STD?
You can get and pass STDs through vaginal, anal, or oral sex. Trichomoniasis can also picked up from contact with damp or moist objects such as towels, wet clothing, or a toilet seat, if the genital area gets in contact with these damp objects. Some STDs cause no symptoms. But STDs can still be passed from person to person even if there are no symptoms.

What are the symptoms of STDs?
Here are some STDs and their symptoms.

How do you get tested for STDs?
Talk with your doctor or nurse about getting tested for STDs. She or he can tell you how to test for each STD.

Can STDs cause health problems?
Yes. While each STD causes different health problems, overall, they can cause cervical cancer and other cancers, liver disease, pelvic inflammatory disease, infertility, pregnancy problems, and other complications. Some STDs increase your risk of getting HIV/AIDS. HIV/AIDS can cause a number of health problems and raise the risk of getting life-threatening diseases and certain forms of cancer.

How are STDs treated?
The treatment depends on the type of STD. For some STDs, treatment may involve taking medicine or getting a shot. For other STDs that can’t be cured, like herpes, there is treatment to relieve the symptoms.

How do STDs affect pregnant women and their babies?
STDs can have many of the same consequences for pregnant women as women who are not pregnant. An STD may also cause early labor, cause the water to break early, and cause infection in the uterus after the birth.

Some STDs can be passed from a pregnant woman to the baby before and during the baby’s birth. Some STDs, like syphilis, cross the placenta and infect the baby while it is in the uterus. Other STDs, like gonorrhea, chlamydia, hepatitis B, and genital herpes, can be passed from the mother to the baby during delivery as the baby passes through the birth canal. HIV can cross the placenta during pregnancy, and infect the baby during the birth process.

The harmful effects to babies may include low birth weight (less than five pounds), eye infection, pneumonia, infection in the baby’s blood, brain damage, lack of coordination in body movements, blindness, deafness, acute hepatitis, meningitis, chronic liver disease, cirrhosis, or stillbirth. Some of these problems can be prevented if the mother receives routine prenatal care, which includes screening tests for STDs starting early in pregnancy and repeated close to delivery, if necessary. Other problems can be treated if the infection is found at birth.

What can pregnant women do to prevent problems from STDs?
Pregnant women should be test for these STDs on their first prenatal visit:

Chlamydia
Gonorrhea
Hepatitis B and C
HIV
Syphilis
In addition, some experts recommend that women who have had a premature delivery in the past be screened and treated for bacterial vaginosis at the first prenatal visit. Even if a woman has been tested in the past, she should be tested again when she becomes pregnant.

Chlamydia, gonorrhea, syphilis, trichomoniasis, and bacterial vaginosis (BV) can be treated and cured with antibiotics during pregnancy. There is no cure for viral STDs, such as genital herpes and HIV, but antiviral medication for herpes and HIV may reduce symptoms in the pregnant woman. For women who have active genital herpes lesions at the time of delivery, a cesarean delivery (C-section) may be performed to protect the newborn against infection. C-section is also an option for some HIV-infected women. Women who test negative for hepatitis B may receive the hepatitis B vaccine during pregnancy.

Do STDs affect breastfeeding?
Talk with your doctor, nurse, or a lactation consultant about the risk of passing the STD to your baby while breastfeeding. If you have either chlamydia or gonorrhea, you can keep breastfeeding. If you have syphilis or herpes, you can keep breastfeeding as long as the sores are covered. Syphilis and herpes are spread through contact with sores and can be dangerous to your newborn. If you have sores on your nipple or areola (darker skin around the nipple), you should stop breastfeeding on that breast. Pump or hand express your milk from that breast until the sore clears. Pumping will help keep up your milk supply and prevent your breast from getting engorged or overly full. You can store your milk to give to your baby in a bottle for another feeding. But if parts of your breast pump that contact the milk also touch the sore(s) while pumping, you should throw the milk away.

If you are being treated for an STD, ask your doctor about the possible effects of the drug on your breastfeeding baby. Most treatments for STDs are safe to use while breastfeeding.

If you have HIV, do not breastfeed.
You can pass the virus to your baby.

What can I do to avoid getting an STD?
There are steps you can take to keep from getting an STD:

Don’t have sex. The best way to prevent any STD is to practice abstinence, or not having vaginal, oral, or anal sex.
Be faithful. Have a sexual relationship with one partner who has been tested for STDs and is not infected is another way to reduce your chances of getting infected. Be faithful to each other, meaning that you only have sex with each other and no one else.
Use condoms. Protect yourself with a condom EVERY time you have vaginal, anal, or oral sex. Condoms should be used for any type of sex with every partner. For vaginal sex, use a latex male condom or a female polyurethane condom. For anal sex, use a latex male condom. For oral sex, use a dental dam. A dental dam is a rubbery material that can be placed over the anus or the vagina before sexual contact.
Know that some methods of birth control, like birth control pills, shots, implants, or diaphragms, will not protect you from STDs. If you use one of these methods, be sure to also use a latex condom or dental dam (used for oral sex) correctly every time you have sex.
Talk with your sex partner(s) about STDs and using condoms. It’s up to you to make sure you are protected. Remember, it’s YOUR body!
Talk frankly with your doctor or nurse and your sex partner(s) about any STDs you or your partner have or had. Try not to be embarrassed.
Have regular pelvic exams. Talk with your doctor about how often you need them. Many tests for STDs can be done during an exam. Ask your doctor to test you for STDs. The sooner an STD is found, the easier it is to treat.
