High-risk groups

The use of a condom is essential to protect yourself and your partners against STDs. If you have any concerns, you should have an STD screening test. In the event of an infection, follow the treatment correctly and inform your sexual partners.

Types of behaviour that favour the transmission of syphilis

The transmission of STDs can generally be linked to certain types of behaviour:

  • having sexual intercourse without using a condom
  • having sexual intercourse with an infected partner.

Syphilis mostly affects men, in particular men who have sex with men (MSM) aged between 30 and 50.

Sciensano compiles two reports each year documenting the evolution of STDs in Belgium. The reports are based on data-collection networks.
