Prevalence of sexually transmitted infections in Europe

Currently there is a systematic review conducted on the prevalence of 4 sexually transmitted infections in Europe: chlamydia, gonorrhoea, syphilis and trichomoniasis. We are conducting extensive literature searches in bibliographic databases but are also interested in grey literature. We would be very grateful if you could:

• indicate to us any reports on the prevalence of any of the 4 STIs in your country, published/conducted within the last 10 years, that has not been published in a peer-reviewed journal
• and/or forward our request to experts in the field in your country!

(The focus of this request is on grey literature, but please don’t hesitate to also indicate relevant peer-reviewed literature, especially recent publications.)

Please note that for this review we are not interested in incidence estimates derived from routine surveillance (i.e., number of case notifications per national/regional population), but only in prevalence estimates derived from a study where the total population of tested individuals is known and described.
