Determining whether you're dealing with a stomach bug or food poisoning comes down to symptoms and timing. Food poisoning usually manifests within a few hours after consuming contaminated food, highlighted by nausea, vomiting, and diarrhea. On the other hand, a stomach bug, like norovirus, develops gradually over a day or two and might include fever, body aches, and additional cold-like symptoms. Both conditions share similar symptoms, but timing and the presence of fever can be key differentiators.
