GUMCAD STI Surveillance System
Information about the collection and reporting of GUMCAD, the surveillance system for sexually transmitted infections (STIs) in England.
About
GUMCAD is the mandatory surveillance system for STIs and collects data from all publicly commissioned sexual health services (SHSs) in England. It is an electronic, pseudonymised and depersonalised data set. See further details on the development of the GUMCAD STI Surveillance System.
GUMCAD collects data on the services provided and diagnoses made at SHSs including:
- STI and HIV testing
- STI diagnoses
- vaccinations offered in these services
GUMCAD data is:
- reported quarterly to UKHSA by all SHSs
- published quarterly as provisional data, and annually as official statistics

Information on STI tests, diagnoses and the provision of SHSs in England is available in a variety of outputs.
Sexually transmitted infections (STIs) annual data tables
These official statistics present information on STI diagnoses and SHSs provided in England by demographic characteristics and geographical region.

These provide local authority data on STI and HIV diagnoses and services through interactive maps and charts.
These are restricted-access reports for monitoring local, regional and national STI trends. They are only accessible to registered NHS and local authority users only.
