What is syphilis?
Syphilis is a bacterial infection. The infection has 4 stages: primary, secondary, early latent and late latent.
How can I get syphilis?
You can get syphilis from close contact or sexual contact with another person who is infected. Syphilis is spread through:
- Skin-to-skin contact with a syphilis sore (lesion) or rash.This can happen through external or internal contact with a person's mouth, genitals, or rectum when a sore or rash is present
- Exchange of bodily fluids, such as blood, semen, or vaginal fluid
- Sharing sex toys
If you are pregnant and have syphilis, you can spread the infection to your baby during pregnancy or birth.
While anyone can acquire syphilis, most people diagnosed with syphilis in B.C. are men who identify as gay, bisexual, or men who have sex with men (gbMSM). Syphilis rates have increased greatly for gbMSM.
Syphilis can be transmitted during any of the 4 stages of infection. Your risk of having syphilis is greater if you already have another sexually transmitted infection (STI).
What are the symptoms?
Each stage of syphilis has a different set of symptoms. The symptoms can vary or be so mild that you may not know you have a syphilis infection.
During the primary stage, a painless sore can develop anywhere on your body that came into contact with a person who has a syphilis infection. The sore usually appears between 3 and 90 days after getting the infection. Often, the sore will not be noticeable on your body. The sore will go away on its own within a few weeks, but the disease will continue to progress.
The secondary stage usually starts about 14 to 90 days after getting a syphilis infection. During this stage a non-itchy rash may develop. The rash can appear anywhere on your body, but it is most often found on your chest, belly, genitals, palms of your hands, and soles of your feet. You may not notice the rash, but you can still transmit the disease to other people. The rash usually disappears but it can come back months later. Other symptoms may include headache, fever, hair loss, swollen lymph nodes and bumps or mucous patches inside the mouth, anus, penis or vagina.
After the rash goes away, and if you do not receive treatment, the disease will progress to the latent, or hidden, stages. The latent period can last up to 30 years or longer. During this time, you may not have any symptoms.
There are two latent stages of syphilis:
- Early latent stage is when a person has acquired a syphilis infection within the past year. People who have 'early' syphilis can transmit the infection more easily
- Late latent stage is when a person has a syphilis infection for more than 1 year
How to get tested for syphilis
Visit your health care provider to get any syphilis symptoms, like sore(s) or rashes, tested. Your health care provider may give you a referral for lab work to get your blood tested.
It is recommended that gbMSM and anyone who has multiple sexual partners be tested for syphilis every 3 to 6 months or immediately if they have symptoms.
Screening for syphilis is recommended as part of prenatal screening for anyone who is pregnant. If you are pregnant, speak to your health care provider to learn about your risk of getting STIs, including syphilis. They can help determine if you need STI screening.
You can access testing directly at certain lab locations in B.C. To locate the nearest testing clinic or get tested online, visit Smart Sex Resource at https://smartsexresource.com/sex-talk/talk-about-it and/or Get Checked Online at www.getcheckedonline.com.
What are the complications?
If you are not treated for syphilis, complications may occur early on in the infection or several years later. Complications may be neurologic (hearing or vision loss, dizziness) or cause damage to your brain, heart and other organs in your body, which can lead to death.
Untreated syphilis in a pregnant person can cause complications such as a miscarriage, premature birth or stillbirth, low birth weight, or cause the baby to be born with syphilis (called congenital syphilis).
What is the treatment?
During any stage, syphilis can be treated with antibiotics. Antibiotic treatment cannot undo the damage already caused by syphilis in the late latent stage, but it can prevent further damage. After treatment, you must have blood tests to make sure the treatment worked.
Your sexual partners within the last 3 to 12 months should be tested and treated for syphilis. This will depend on what stage of syphilis you are diagnosed with. Do not have sex until 2 weeks after you and your partner(s) have finished the treatment and you have confirmed that the treatment was effective.
Will my birth control pills work if I am taking antibiotics?
There is very little evidence to show that antibiotics reduce how well hormonal forms of birth control work. Examples of hormonal birth control include the pill, the patch, the ring, or the shot. If you are being treated with antibiotics, it is important to keep using your birth control as you normally would. If you have concerns, also use condoms until your next period comes after completing the antibiotics, or speak to your health care provider for more information.
