1. Decoding Stomach Flu (Viral Gastroenteritis)
Stomach flu, or viral gastroenteritis, occurs when the stomach and intestines become inflamed, triggered by a viral infection. According to Dr. Gabriela Delgado, a primary care physician at Northwestern Medicine, rotavirus and norovirus are among the most common culprits. These viruses spread through contaminated surfaces and close contact. FOODS.EDU.VN emphasizes the importance of understanding how these viruses spread, empowering you to take proactive steps to protect yourself and your loved ones.
Symptoms:
- Nausea
- Vomiting
- Diarrhea
- Stomach pain and cramps
- Low-grade fever
Duration: Typically, stomach flu lasts about 48 hours, but severe cases can linger for over two weeks.
Treatment: Hydration and rest are key. Over-the-counter anti-nausea or anti-diarrhea medications may provide relief.
Prevention: Frequent hand washing, especially after using the bathroom and before meals, is essential. For infants, consult your pediatrician about the rotavirus vaccine. FOODS.EDU.VN provides in-depth articles on maintaining excellent hygiene practices.
2. Unraveling Food Poisoning
Food poisoning arises from consuming food contaminated with harmful bacteria, viruses, or parasites. Unlike stomach flu, which stems from contact with infected bodily fluids, food poisoning is directly linked to contaminated food sources.

Duration: Symptoms usually improve within 48 hours, depending on the specific contaminant.
Treatment: Rest, fluids, and over-the-counter medications can ease symptoms. Severe cases might require hospitalization.
Prevention: Proper food handling, cooking, and storage are critical. Avoid raw or undercooked foods, and always wash hands thoroughly before preparing meals. Report any suspected foodborne illness incidents to your local health department. At FOODS.EDU.VN, discover comprehensive guides on safe food storage temperatures and cooking guidelines for various foods.
3. Dissecting Flu (Influenza)
Influenza, commonly known as the flu, is a contagious respiratory illness caused by the influenza virus.
