Comments from Expert Advisory Group
Antibiotic therapy is not indicated for infectious diarrhoea for patients who are systemically well. If patients are systemically unwell or post-antibiotic, suggesting Clostridioides difficile , antibiotics may be indicated, discuss with Consultant Microbiologist.
Consider seeking advice from a consultant microbiologist and send a faecal sample to microbiology for testing in the following circumstances:
- The patient is systemically unwell or has severe or bloody diarrhoea
- The patient has persistent diarrhoea > 5 days
- The patient is a returning traveller
- The patient is at high risk for severe disease
Consider shigellosis as a differential diagnosis in adult males who present with bloody diarrhoea.
