Via ECDC: Chlamydia infections highest among young women: new ECDC report. Click through for links and to download the full report. Excerpt from the summary:
No end to the trend: with more than 385 000 notified cases in 2012, chlamydia is the most commonly reported sexually transmitted infection across Europe. Data from the report "Sexually transmitted infections in Europe 2012" show that two thirds of all chlamydia infections are diagnosed in young people between 15 and 24 years of age, with 65% of all diagnoses amongst young women. Rates for gonorrhoea and syphilis are also on the rise in many European countries.
The new report covers EU-wide data and trends on the five sexually transmitted infections (STI) under surveillance in the countries of the European Union and European Economic Area (EU/EEA): chlamydia, gonorrhoea, syphilis, congenital syphilis and lymphogranuloma venereum (LGV) infection.
The available data suggest that there are ongoing epidemics of chlamydia, gonorrhoea and syphilis which affect different groups across Europe as far as age, gender and sexual orientation are concerned.
Overall, young adults and men having sex with men (MSM) are the key populations involved in the transmission of STI in Europe. Chlamydia is the only STI which is reported more frequently in women than men, with a rate of 211 per 100 000 population in women and 153 in men. This ratio is, however, influenced by the fact that women are generally tested and screened more often than men.
