They are young, mostly female and their number is constantly growing: with nearly 344 000 notified cases in 2009 chlamydia is the most frequently reported sexually transmitted infection (STI) across Europe.
With more than 32 000 cases, gonorrhoea was the second most commonly reported sexually transmitted infection (STI) in Europe in 2010. As data from the ECDC report Gonococcal antimicrobial susceptibility surveillance in Europe 2010 illustrates, gonococci have become more resistant to common agents for treatment and show reduced susceptibility to newer antibiotics. “This indicates the risk that gonorrhoea may become an untreatable disease in the near future”, stresses ECDC Director Marc Sprenger.
