Data are collected by calendar year and not financial year. 2. The data available from the KC60 statutory returns are for diagnoses made in GUM clinics only. Diagnoses made in other clinical settings, such as general practice, are not recorded in the KC60 dataset. 3. The data available from the KC60 statutory returns are the number of diagnoses made, not the number of patients diagnosed. For example, individuals may be diagnosed with chlamydia several times in one year and each diagnosis will be counted separately. 4. The information provided has been adjusted for missing clinic data. 5. Data are unavailable for 2007. 6. The total population was used for the calculation of overall rates.

In addition, data from the National Chlamydia Screening Programme (NCSP) shows that between 1 April 2003 and 31 December 2007, among those aged 13-24, there were 565,424 tests for chlamydia, 496,594 confirmed negatives and 54,017 confirmed positive diagnoses.

Notes: 1. The data are from NCSP registered screening venues and includes the Boots pathfinder project. Data as of 29 January 2008 2. The NCSP screens those aged under 25 years. 3. The NCSP began screening on 1 April 2003 and so data are only available from that date onwards. 4. The NCSP collects number of tests and not number of people tested. We assume that number of tests is a close proxy for number of people tested as re-testing is rare. 5. The data available from the NCSP are the number of diagnoses made and not the number of patients diagnosed. Source: NCSP.
