Syphilis

Syphilis is a very serious STI caused by a bacteria called Treponema pallidum. It can affect your brain and other organs.

How do I get syphilis?

Syphilis can be passed on through unprotected vaginal, anal and oral sex with an infected person. It can also been spread through intimate or skin-to-skin contact with someone who has syphilis sores or a syphilis rash. An infected mother can pass syphilis onto her baby during pregnancy via the placenta. 

How do I know if I have syphilis?

There are three stages of syphilis, and you may not notice the first two stages as the first signs don’t last long.

first (primary) stage: 3-12 weeks after exposure: Some people get an ulcer or sore around the genital area or mouth. It can be any size or shape is painless, doesn’t bleed and feels like a hard button. If untreated it will heal and disappear after a few weeks. This however does not mean you do not have the infection. The bacteria are in the blood stream and are spreading around the body.

second (secondary) stage: About 2-6 months after exposure, you can develop a skin rash. This can present on the face, palms and soles of the feet and you can get swollen glands, some lumps in the moist areas of the body, and hair loss. You can also get headaches, pains in your bones, muscles and joints. This can last for 6 months or more and then you can go into a ‘latent stage’ where you still have the disease and are infectious but have no symptoms. This can last up to 2 years.

third (tertiary) stage: The disease can now affect the brain, heart, large blood vessels, spinal cord, skin and bones. This can cause disability and death.

During an STI check, the doctor at Marie Stopes United Kingdom can do a simple blood test for syphilis. Please see your GP if you have any symptoms immediately so that you can be tested and treated. 

How do I get treated for syphilis?

Syphilis is treated with antibiotics and you will need to take a full course. After your course, you will need another blood test to make sure you are cured. 

What would happen if I did not get treatment for syphilis?

Syphilis can be a serious and life-threatening condition if not treated. It can affect the brain and spinal cord and can lead to disability and death. 

How can I protect myself from getting syphilis?

  • Always use condoms or dams and a water-based lubricant when having sex — even oral sex.
  • If in a long-term relationship, ensure each partner has been tested before stopping condom use, and that neither of you has other partners.
  • Have regular STI checks.
  • Discuss STIs with your partner, even when it is difficult to talk about. Your partner will appreciate your honesty and that you don’t want to infect him/her. You have the right to know if they are infected too.
