 Viral gastroenteritis The stomach, small intestine and large intestine (colon) are part of your digestive tract, which processes the foods you eat. Viral gastroenteritis is an inflammation of these organs caused by a virus. The stomach, small intestine and large intestine (colon) are part of your digestive tract, which processes the foods you eat. Viral gastroenteritis is an inflammation of these organs caused by a virus. Although it's commonly called stomach flu, gastroenteritis isn't the same as influenza. The flu (influenza) affects only your respiratory system — your nose, throat and lungs. Gastroenteritis, on the other hand, attacks your intestines, causing signs and symptoms such as: 
Watery, usually nonbloody diarrhea — bloody diarrhea usually means you have a different, more severe infection
Nausea, vomiting or both
Stomach cramps and pain
Occasional muscle aches or headache
Low-grade fever
 Depending on the cause, viral gastroenteritis symptoms may appear within 1-3 days after you're infected and can range from mild to severe. Symptoms usually last just a day or two, but occasionally they may last up to 14 days. Because the symptoms are similar, it's easy to confuse viral diarrhea with diarrhea caused by bacteria, such as Clostridioides difficile, salmonella and Escherichia coli, or parasites, such as giardia.
