In addition to STTs diagnosed in a GUM clinic, the National Chlamydia Screening programme (NCSP) provides chlamydia screening to asymptomatic people under the age of 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 diagnoses of chlamydia in patients between the ages of 13-24 years between April 2003 and December 2008 in Mid Essex primary care trust (PCT), Essex (which includes Mid Essex PCT, North East Essex PCT, South East Essex PCT and West Essex PCT) and The East of England SHA.
