Chlamydia - Annual Epidemiological Report for 2024
Surveillance and monitoring
For 2024, 27 EU/EEA countries reported 213 443 confirmed cases of chlamydia infection, with a crude notification rate of 63.4 cases per 100 000 population in the 24 countries with comprehensive surveillance systems. This represents a 10% decrease in the crude notification rate compared to 2023, and a 6% decrease compared to 2015, when analysing the rate over time among countries reporting consistently.
Key facts
- Notification rates continued to be highest among women aged 20−24 years in 2024.
- In 2024, transmission between men who have sex with men accounted for 22% of chlamydia cases.
- National notification rates for cases of chlamydia infection ranged between 0.1 and 502 cases per 100 000 population. Differences in chlamydia testing policies, case finding strategies and reporting are considered to have a greater influence on reported chlamydia numbers than actual differences in epidemiology.
