Chlamydia infection - Annual Epidemiological Report for 2019

For 2019, 26 EU/EEA Member States reported 434 184 confirmed cases of chlamydia infection. The crude notification rate was 157 cases per 100 000 population. National notification rates of chlamydia infection varied considerably across the EU/EEA. This is probably due to the differences in chlamydia testing, case finding strategies and reporting rather than being indicative of actual differences in chlamydia distribution. Notification rates continue to be highest among young adult heterosexual women. Over the last five years the number of chlamydia diagnoses reported among men increased by 19% and among women by 9%. During the same period, the number of chlamydia diagnoses among HIV-negative men who have sex with men (MSM) doubled in those countries consistently reporting information on transmission and HIV status.
