Guidance on the collection and reporting of data for GUMCAD, the surveillance system for sexually transmitted infections (STIs) in England.
GUMCAD is the mandatory surveillance system for STIs and collects data on STI tests, diagnoses and services from all commissioned sexual health services in England. It is an electronic, pseudonymised patient-level dataset reported by approximately 400 services.
Public Health England (PHE) co-ordinates and manages the quarterly data collection, processing, storage, analysis, and reporting of GUMCAD data on behalf of the Department of Health and Social Care (DHSC).
- reported quarterly to service providers and local authority sexual health commissioners
- published annually as official statistics
- used for the chlamydia detection rate on DHSC’s Public Health Outcomes Framework
All commissioned specialist (level 3) and non-specialist (level 2) sexual health services are required to complete and return GUMCAD data to PHE.
Further details on the development of GUMCAD are available in this article in Eurosurveillance. Details on the levels of sexual health service provision are available in the Standards for the management of STIs provided by the British Association for Sexual Health and HIV.

How to access GUMCAD data
GUMCAD data are subject to strict data sharing principles which are given in the PHE HIV and STI data sharing policy.
Information on STI tests, diagnoses and sexual health services provided in England are available in a variety of formats.
These official statistics present information on STI diagnoses and sexual health services provided in England by demographic characteristics and geographical region.
These provide local area data on sexual health, reproductive health and HIV diagnoses and services through interactive maps and charts.
These are restricted-access reports for monitoring local, regional, and national sexual health trends. They are accessible to registered NHS and local authority users only. Reports available include:
- local authority STI and HIV epidemiology reports (LASERs)
- GUMCAD STI diagnoses and services reports
- CTAD data quality reports
- NCSP quarterly data tables
- chlamydia re-testing following a positive diagnosis report
The principles for accessing and sharing GUMCAD data are given in the PHE HIV and STI data sharing policy.
A wide array of information on sexual health, reproductive health, and HIV is available from Public Health England and other organisations.
A guide to local and national data helps professionals including local government, service providers and commissioners understand the sexual health, reproductive health and HIV data available across England and how the data can be accessed.
Data request form
