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.
Update during coronavirus (COVID-19) pandemic:
Gastrointestinal infections cause an estimated 17 million cases in the UK each year. Bacterial gastroenteritis is particularly common in summer months and outbreaks of zoonotic infections, such as campylobacteriosis, salmonellosis and Shiga toxin-producing E. coli (STEC) occur every year.
Although a vast majority of cases of gastroenteritis cause self- limiting diarrhoea, symptoms such as fever and diarrhoea can be mistaken for COVID-19. Certain gastrointestinal infections like STEC can cause serious complications such as haemolytic uraemic syndrome (HUS), and Listeria monocytogenes infections can be fatal in severely immunocompromised patients.
During the coronavirus (COVID-19) pandemic, the UK Government advice to stay at home and social distancing strategies have changed patterns of shopping, cooking and food consumption in the population. It is therefore important to be highly vigilant of complicated cases of gastroenteritis in the coming months.
Diagnosis
Gastrointestinal bacteria reference unit (GBRU) is the reference laboratory for a range of gastrointestinal pathogens.
COVID-19 update:
All routine services have been resumed.
Clinicians and laboratories are advised to continue submitting isolates and appropriate clinical samples to the GBRU for detection, identification and typing of bacterial pathogens.
