STI – Chlamydia

Sexually Transmitted Infections (STIs) are diseases caused by harmful bacteria or viruses. These infections are transmitted through unsafe sexual contact.

The chlamydia bacterium causes an infection in the urethra, cervix, rectum, or throat. The infection can spread to the epididymis, uterus, or fallopian tubes. A concerning aspect of this infection is that there are often no clear symptoms. However, an infection with this bacterium can lead to infertility in women.

Chlamydia can be effectively treated with medication. It is important to consult a doctor or a sexual health clinic if you experience symptoms or suspect a possible infection. There is currently no vaccine for chlamydia.

Where does chlamydia occur?

You can get chlamydia anywhere in the world. The risk of infection is often higher when you are far from home and out of your usual routine. Therefore, good education and preventive measures are essential, especially when travelling. In the Netherlands, chlamydia is one of the most common STIs, particularly among young people under the age of 25.

How to prevent chlamydia?

Unsafe sex always carries the risk of contracting an STI. If you have sex with individuals from other countries, the risk of getting other STIs may be greater than in the Netherlands. It is important to protect yourself and your sexual partners from STIs. You can do this by practising safe sexual contact, for example, by using condoms and avoiding risky sexual techniques. Be honest with your sexual partners and inform them if you have been diagnosed with an STI.
