The symptoms of E. coli infection of the digestive system include:
- Diarrhoea – This can be watery or bloody, and mild or severe.
- Belly pain
- Vomiting – This is more common in children infected with one specific type of E. coli.
E.coli that causes bloody diarrhoea sometimes also causes problems with the kidneys or blood. This is not common, but can be serious if it does happen.
