Syphilis is caused by the Treponema pallidum bacterium and is treated with antibiotics. If left untreated, syphilis causes severe health problems after a few months or several years which result in permanent damage or even death.

Who does Syphilis affect?

The number of syphilis infections reported in Switzerland is growing every year. The following groups are at particular risk:

  • Men who have sex with men
  • Sex workers and their clients

How are Syphilis transmitted?

Syphilis can be transmitted through almost any sexual practice, but especially oral, vaginal and anal sex. It is usually transmitted through direct contact with an infected patch of skin. Syphilis can also be transmitted via hands or sex toys.

It is unlikely to become infected via toilet seats, used towels or other materials.

Pregnant people can pass the bacteria on to their unborn child (Syphilis connata).

How can I protect myself against Syphilis?

Condoms only provide limited protection against contracting syphilis. It is possible to become infected during sex, and this is no reason to be ashamed. Anyone who has sex can become infected. It is important to take regular tests to ensure early detection of a potential infection.

What symptoms can appear with Syphilis?

Syphilis develops in three stages. At first, the symptoms are often imperceptible. They may include small rashes, swelling of the lymph nodes or an ulcer (primary lesion). After a few weeks, these primary-stage symptoms disappear, but the bacteria spread through the entire body.

How do they test for Syphilis?

A blood test is usually carried out (e.g. at a sexual health clinic) to detect syphilis bacteria.

Rapid tests, which deliver a result in just a few minutes, are also available. However, these are not recommended due to their inaccuracy.

How are Syphilis treated?

Syphilis is treated with penicillin. There is a good chance of curing syphilis in the early stages. It is essential to take a blood test after three months to check the efficacy of the treatment.

If you have syphilis, it is especially important to inform your sexual partners of your infection so that they can get tested. This will prevent them from reinfecting you or passing the infection on to others.
