Medical management
An extensive review of tropical disease is outside the scope of these ID guidelines but the following may help in logical diagnosis and management based on main symptoms.
Diarrhoea
- Most commonly caused by E.coli as traveller’s diarrhoea. Most cases resolve spontaneously. However, if:
- Frequent bowel action, vomiting, fever or blood in stool, may benefit from antibiotic treatment
- Use ciprofloxacin 500mg bd or norfloxacin 400mg bd for 3-5 days
- Frequent bowel action, vomiting, fever or blood in stool, may benefit from antibiotic treatment
- If persistent investigate with:
- Stool microscopy and culture and PCR
- If diarrhoea is chronic, consider stool for lactose intolerance testing
- Consider abdomen U/S and or endoscopy (upper and/or lower)

Commonly caused by:
- Influenza
- Bacterial pneumonia
