NCSP: programme overview

An overview of the National Chlamydia Screening Programme (NCSP).



Chlamydia is a common bacterial sexually transmitted infection which is frequently asymptomatic. This overview of the National Chlamydia Screening Programme (NCSP) details the aims of the NCSP and the evidence base for it.

The programme overview includes information on the following objectives:

  • prevent and control chlamydia through early detection and treatment of asymptomatic infection
  • reduce onward transmission to sexual partners
  • prevent the consequences of untreated infection
  • ensure all sexually active under 25 year olds are informed about chlamydia, and have access to sexual health services that can reduce risk of infection or transmission
  • normalise the idea of regular chlamydia screening among young adults so they expect to be screened annually or when they change partner
