Changes in the Trend of Sexually Acquired Chlamydia Infections in Sweden and the Role of Testing: A Time Series Analysis

Abstract

A study on notified sexually acquired chlamydia cases and testing in Sweden found that recently decreasing chlamydia notification rates are not affected by testing volumes and most likely reflect decreasing incidence rates. Supplemental digital content is available in the text.

Prevention strategies for sexually transmitted infections, HIV, and viral hepatitis in Europe

“…40 The strategy included a universal surveillance system for chlamydia, with free testing, counselling, treatment, and partner notification as well as raising awareness on condom use and improving access to testing among young people, and improving sexual education in schools, which targeted to reduce the prevalence of C. trachomatis infection by 2014. 41 A new mutant variant generating false negative test results caused a sharp increase in chlamydia in 2007, 42 leading to the development of a chlamydia action plan for 2009–2014. This resulted in a decline in reported chlamydia infections and reduced the frequency of the new variant 43 being an excellent example of an effective response.…”

Knowledge about and prevalence of Chlamydia trachomatis in a population-based sample of emerging Croatian adults

“…ECDC recommends that widespread opportunistic testing or screening of sexually active men and women under 25 years in case of sufficient resources and existence of a monitoring and evaluation system, none of which is in place in Croatia [21]. However, effectiveness of chlamydia screening on lowering chlamydia prevalence, preventing pelvic inflammatory disease, ectopic pregnancy or female infertility has been questioned and is a subject of ongoing debates [22,23]. Targeted testing combined with effective case management strategies, which includes partner notification, and the emphasis on primary prevention of STIs might be a reasonable way forward for chlamydia control in Croatia [20,24,25].…”
