About this release

This release by Public Health Scotland (PHS) provides information on reported laboratory-confirmed gastrointestinal and zoonotic (GIZ) pathogen trends in Scotland for the calendar year 2024. Gastrointestinal infections (GI) are infections that affect the digestive system, leading to symptoms like diarrhoea, vomiting, and abdominal pain.  Zoonotic infections are diseases that can be transmitted between animals and humans. Some GI infections fall into both categories when they originate in animals.

Data presented include temporal trends in laboratory reports spanning 2015-2024 and national level or UK-wide GIZ pathogen outbreaks investigated during the year. In addition, seasonality, demographics, and reporting rates by Scottish NHS Boards of residence are provided for GIZ pathogens where 100 or more reported cases were recorded during 2024.
