Syphilis is a sexually transmitted infection (STI) caused by a type of bacteria. If it's not treated by a doctor, it can get worse over time and cause serious health problems.
The infection can be active at times and not active at other times. When the infection is active, you have symptoms. When it's not active, you don't have symptoms. But you still have syphilis.
You can get syphilis without having sexual intercourse. Just being in close contact with an infected person's genitals, mouth, or rectum is enough to expose you to the infection.
Syphilis is caused by a type of bacteria. The bacteria are usually spread through sexual contact. They most often enter the body through the tissues that line the throat, nose, rectum, penis, or vagina.
One of the first signs of syphilis is an open sore that appears wherever the bacteria entered the body. As syphilis spreads, a person may get a skin rash and have other symptoms like a fever, swollen lymph nodes, and weight loss. Without treatment, syphilis may cause blindness and nerve and heart problems.
Your doctor will do a physical examination and ask about your symptoms and sexual history. You'll probably have one or more blood tests, especially if you don't have sores. If you do have sores, your doctor may test the fluid from one of the sores to check for syphilis bacteria.
At any stage of infection, antibiotics work well to cure syphilis. They can't undo the damage already caused by late-stage syphilis. But they can help you avoid further problems from the infection. You and any sex partners that you may have exposed to the infection will need to be treated.
Here are some ways to help prevent STIs.
Vaccines are available for some STIs, such as HPV. Ask your doctor for more information.
An infected person who has a sore or a rash can pass syphilis to others. It's usually spread during vaginal, anal, and oral sex. But it can be spread by any close contact with the genitals, mouth, or rectum of an infected person. If you're infected while you're pregnant, you can pass syphilis to your baby.
Syphilis develops in four stages. Each stage has a different set of symptoms.
One of the first signs of syphilis is a painless open sore called a chancre. Chancres are often found in the mouth, the anus, or the genital area. As syphilis spreads throughout the body, a person may get a skin rash and have other symptoms like a fever, swollen lymph nodes, and weight loss.
You may not notice symptoms of syphilis. Sometimes they're the same as symptoms for other infections. This can cause someone with the infection to put off seeing a doctor. And it can make it harder for a doctor to tell if you have syphilis.
If syphilis isn't found and treated in the early stages, it can cause other serious health problems. These can include blindness, problems with the nervous system and the heart, and mental disorders. It can also cause death.
The main symptom of the first stage of syphilis is an open sore. A rash and other symptoms occur during the second stage. That's followed by a time without symptoms. Syphilis can move to the late (tertiary) stage, causing serious problems. Antibiotics can't undo damage, but they can cure syphilis at any stage.
Call to make an appointment if you:
Do not have sexual intercourse or other sexual contact until you have been treated by a doctor. If you are diagnosed with syphilis, your sex partner(s) will need to be treated also.
In most areas, public health units or sexual health clinics are able to diagnose and provide assessment and treatment of early syphilis and other STIs.
Watchful waiting is a wait-and-see approach. It's not a good choice if you think you were exposed to or have syphilis or another STI. Any symptoms or other changes that suggest syphilis or another STI should be checked by a doctor.
Your doctor will do a physical examination. You'll be asked about your symptoms and your sexual history.
The diagnosis of syphilis is usually confirmed with one of several blood tests. This is especially true if you don't have sores. If you have sores, a doctor may look at the fluid from one of the sores with a microscope to look for syphilis bacteria. (This is called a dark-field examination.)
To diagnose the primary and secondary stages of syphilis, the doctor may do a lumbar puncture (spinal tap) in some cases.
More testing should be done to look for other sexually transmitted infections, such as:
Syphilis can be cured with antibiotics. Penicillin is the preferred medicine. You will need to be treated, and so will any sex partners that you may have exposed to the infection.
At any stage of the infection, antibiotics work well to cure syphilis. They can't undo the damage already caused by late-stage syphilis. But they can help you avoid further problems from the infection.
You cannot treat syphilis on your own. It must be treated with medicine that only a doctor can give you. Treatment helps you avoid other serious health problems. And it keeps you from spreading syphilis to others.
Being treated during pregnancy can help you avoid miscarriage or stillbirth. It can also help keep your baby from being born with syphilis.
