Gastrointestinal infections: guidance, data and analysis

The characteristics, diagnosis, management and epidemiology of gastrointestinal infections.

Infectious intestinal diseases affect 1 in 5 people in the UK each year and symptoms are not confined to diarrhoea and vomiting.

Public Health England (PHE) monitors trends in infection and outbreaks, drawing on data from:

  • PHE reference laboratories
  • the national laboratory reporting scheme
  • consultants in communicable disease control (CCDCs)
  • environmental health officers (EHOs)
  • microbiologists

For trends in zoonotic infection in humans and animals, see Zoonoses in the UK.


Gastrointestinal bacteria reference unit (GBRU) is the reference laboratory for a range of gastrointestinal pathogens. Details about GBRU services and request forms are available from the detailed guide below.
