Currently data are only collected nationally on diagnoses in genito-urinary medicine (GUM) clinics and at primary care trust (PCT) level in the National Chlamydia Screening Programme (NCSP).
Information on the diagnoses of sexually transmitted infections (STIs) in GUM clinics is only available at strategic health authority (SHA) level. The London SHA includes Romford and the Greater London areas. The East of England SHA includes Essex.
The number of selected sexually transmitted infections diagnosed in those under the age of 25 in the London SHA and the East of England SHA represented by gender in 2006, the latest date for which information is available, is shown in table 1.
The total number of chlamydia screens and chlamydia positive screens done by the NCSP, by PCT of residence in 2006 for the London SHA and East of England SHA is given in tables 2 and 3.
SHA Male diagnoses Female diagnoses Total diagnoses 2006 London 8,872 12,534 21,406 2006 East of England 4,192 6,230 10,422 Notes: 1. Data by age group are only available for the five main STIs, primary and secondary syphilis, uncomplicated gonorrhoea, uncomplicated chlamydia, anogenital herpes (first attack) and anogenital warts (first attack). As such the figures provided in table 1 are for these five STIs only. Data on the treatment of STIs are not available. 2. Data by age group are only available in the following age groups: <20, 20-24, 25-34, 35-44 and 45+. 3. 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. 4. 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. 5. The information provided has been adjusted for missing clinic data. 6. Data are unavailable for 2007.
