Key facts

• In 2014, 396 128 cases of chlamydia infection were reported in 26 EU/EEA Member States.
• The overall notification rate was 187 per 100 000 persons.
• Notification rates of chlamydia infection vary considerably across Europe, with the highest country-specific rates more than 5 000 times the lowest rates. This is mainly a reflection of the differences in chlamydia testing and case finding rather than real differences in chlamydia prevalence.
• Notification rates continue to be highest among young adult women and heterosexuals.
• The overall trend appears stable over recent years, however varying trends are observed at the country level.

 

 

Methods

In 2014, the majority of countries reported data based on EU case definitions; five countries reported data based on national case definitions, and four countries did not report which case definition they were using. Surveillance systems for chlamydia in Europe vary: 20 countries have comprehensive surveillance systems, and six have sentinel systems which only capture chlamydia diagnoses from a selection of clinics (Annex 1). Reporting of chlamydia infection is compulsory in those 20 countries that maintain a comprehensive surveillances system, with the exception of the United Kingdom. Reporting is voluntary in those countries that maintain a sentinel systems.

In the analyses below, data from sentinel systems are not used in the calculation of rates as the coverage is not clear and denominators are therefore not available. In addition, cases are classified according to the date of diagnosis in all presented analyses. The use of incompatible age formats meant that data from the following countries were excluded from the analysis of age groups for the specified years: Austria (2007–2008), Hungary (2007–2008), and Poland (2006–2014). Lithuania did not report information on age between 2003 and 2007.
