Teen STI Card—Syphilis

Think you can’t get syphilis? Are you sure?

Every year, nearly 9 million people under the age of 25 get a new STI (sexually transmitted infection).1 One of these infections is syphilis. If you’ve had sex, you could have an STI. Some STIs cause symptoms. Others don’t. You could have one and not even know it. Some STIs make you sick today and others cause problems later in life. These include serious problems like cancer or infertility. Some can even kill you.

What is syphilis and how do you get it?

Syphilis is a bacterial STI. You get it from having sex with an infected person. You usually get it through contact with sores or infected patches. These can be on the genitals or sometimes even on the mouth. Babies can get it from their mothers during pregnancy. Most infected people don’t notice any symptoms, but they can still pass on syphilis.

Am I safe if I only have oral or anal sex?

Syphilis can also be passed during oral or anal sex.2,3

What happens if I’m infected?

Syphilis symptoms are often similar to those of other diseases. At first, you may get a painless sore for a few weeks. If you don’t get treatment, your syphilis will get worse. Next, you may feel like you have the flu. At this point, you may notice a rash. If you still don’t get treated, syphilis can cause blindness, brain damage, heart damage and death. If you are pregnant, you can have a miscarriage or a stillborn baby. A baby born with syphilis can have serious birth defects.2 Syphilis also increases your chance of getting HIV.

How do you treat syphilis?

Syphilis can be treated with antibiotics. However, they will not repair any damage already done. Delayed treatment can result in serious problems. Both you and your partner must be treated.

Am I safe if I always use a condom?

If you always use condoms for vaginal sex, you can cut your chance of getting syphilis by about half.4,5 So far, there is no evidence that condoms reduce your chance of getting syphilis during oral or anal sex.

What can I do to avoid getting infected?

Avoid sexual activity if you are single. Be faithful to one uninfected partner for the rest of your life. Already had sex? See a doctor and get checked.
