Symptoms: Diarrhea, vomiting, abdominal pain, fever [1] [2] Complications: Dehydration [2] [3] Causes: Viruses, bacteria, parasites, fungi [2] [4] Diagnostic method: Based on symptoms, occasionally stool culture [2] Differential diagnosis: Inflammatory bowel disease, malabsorption syndrome, lactose intolerance [5] Prevention
Symptoms can manifest in a variety of ways and features might give a clue to the underlying condition.
