Stomach flu (gastroenteritis) and food poisoning share similar symptoms, but a key difference lies in their onset time. Food poisoning typically manifests within hours after eating contaminated food, showcasing severe symptoms like nausea, vomiting, and diarrhea abruptly. Stomach flu symptoms develop more gradually over a few days and are often accompanied by fever, body aches, and headache, indicating a viral cause. Also, multiple people getting sick after eating the same food strongly suggests food poisoning.
