To distinguish between food poisoning and a stomach virus, focus on symptom onset and duration. Food poisoning typically begins 1-6 hours after eating contaminated food and can be severe but short-lived. Symptoms include vomiting, diarrhea, and abdominal cramps. Stomach viruses, like norovirus, have a longer incubation period, usually 12-48 hours after exposure, with symptoms that can last longer, up to 1-3 days. Both may share symptoms, but the timing and context (recent meal versus community outbreak) are key indicators.
