Public Health England, Health Protection Report, Vol 9, Number 22 (23rd June 2015)

  • In 2014, over 1.6 million chlamydia tests were carried out in England among young people aged 15 to 24 years.
  • The most commonly diagnosed sexually transmitted infection in 2014 was chlamydia, with 206,774 (47%) diagnoses made. 
  • In 2014, almost 138,000 chlamydia diagnoses were made in England among young people aged 15 to 24 years old, the target population for the National Chlamydia Screening Programme (NCSP). 
  • In 2014, 29% of Upper Tier Local Authorities (UTLAs) achieved a chlamydia detection rate of at least 2,300 per 100,000 among 15 to 24 year olds, the recommended level for this Public Health Outcome Framework indicator. There was a strong relationship between chlamydia testing coverage and chlamydia detection rates in UTLAs. 
  • The NCSP recommends sexually active under-25 year-old men and women should be screened for chlamydia every year, and on change of sexual partner. 
  • The NCSP updated their recommendations for case management in August 2013, to include a routine offer of a re-test around three months after treatment completion, in patients already diagnosed with chlamydia.

Public Health England, National Chlamydia Screening Programme, Information to support the commissioning of chlamydia screening in general practice and community pharmacies (October 2014)

  • In 2013, integration of chlamydia screening as measured through the proportion of screens undertaken in core services reached 69.5%. There is scope to further increase this proportion, particularly in primary care including general practice and community pharmacies.


  • In 2013, both the Local Government Association and the NHS Confederation published documents that clearly outlined the increasing role of community pharmacies in delivering public health services, including chlamydia screening.  Including chlamydia screening in a pharmacy setting is an important way of ‘making every contact count’.


  • The Chief Medical Officer’s Annual Report 2012 ‘Our children deserve better: prevention pays’ states that ‘Commissioners may maximise value by commissioning appropriate sexually transmitted infection (STI) screening services through opportunistic health contacts such as general practice, sexual health services, abortion services, pharmacies and existing resources’.


  • The NCSP’s Standards 7th edition states that at least 70% of chlamydia screening should take place in core services. Core services consist of primary care (General Practitioner (GP) and community pharmacy), sexual reproductive health (SRH), GUM, and abortion services.
