Sexually Transmitted Infections

Volume 485: debated on Wednesday 17 December 2008

To ask the Secretary of State for Health how many cases of each sexually transmitted infection were confirmed in each month of the last four years. (243629)

Data for sexually transmitted infections (STIs) diagnosed in a genitourinary medicine (GUM) clinic are not currently available on a monthly basis. The latest annual data are published in “All new STI episodes seen at GUM clinics in the UK: 1998 to 2007”, a copy of which has been placed in the Library.

In addition to STIs diagnosed in a GUM clinic, the National Chlamydia Screening Programme (NCSP) provides screening to asymptomatic people aged under 25 years of age in England. The NCSP was launched in 2003 when a phased implementation programme started. The following table shows the number of young people between the ages of 13 to 24 screened and diagnosed with Chlamydia each month between 1 April 2004 and 30 September 2008.

Notes:

1. Total number of screens includes all screens done through the NCSP irrespective of result. Therefore please note positivity cannot be calculated using these data presented since the denominator when calculating positivity is based on positive and negative screens only.

2. The data from the NCSP Core Dataset are for Chlamydia screens conducted within the NCSP outside of GUM clinics only.

3. The data presented include all screening tests done through the NCSP, and excludes diagnostic tests and tests of sexual contacts.

4. The data available from the NCSP are the number of screens and not the number of patients screened.
