Sexually transmitted infections: chlamydia, gonorrhoea and syphilis on the rise in France

Published 2026-11-06

Sexually transmitted infections (STIs) are becoming increasingly common in France. Among the most widespread are chlamydia, gonorrhoea and syphilis. These diseases affect all age groups, although young adults are particularly concerned. Specialists stress that many people do not know they are infected, because symptoms are sometimes discreet, or even absent.

Chlamydia, gonorrhoea and syphilis are caused by bacteria. They can be treated with antibiotics, provided they are diagnosed in time. Without treatment, they can lead to serious complications, including fertility problems or damage to the nervous system in the case of syphilis. Regular screening therefore makes it possible to detect an infection quickly and to avoid passing it on to other people.

To protect yourself, the most effective method remains using a condom during every sexual intercourse, whether vaginal, anal or oral. It is also advisable to get tested after a new partner or in case of doubt. In France, there are free and confidential centres, called CeGIDD, which offer tests and consultations without needing to present a health insurance card. Some STIs, such as hepatitis B or human papillomavirus, can also be prevented through vaccination.

In summary, the rise in STIs in France shows the importance of prevention. Condoms, regular screening and vaccination remain the best means of limiting the spread of these infections. Health authorities encourage those concerned to talk openly with their doctor or another health professional.
