Gastroenteritis

Gastroenteritis (also known as gastric flu, stomach flu, and stomach virus, although unrelated to influenza) is marked by severe inflammation of the gastrointestinal tract involving both the stomach and small intestine resulting in acute diarrhea and vomiting. It can be transferred by contact with contaminated food and water. The inflammation is caused most often[citation needed] by an infection from certain viruses or less often[citation needed] by bacteria, their toxins (e.g. SEB), parasites, or an adverse reaction to something in the diet or medication.

At least 50% of cases of gastroenteritis resulting from foodborne illness are caused by norovirus. Another 20% of cases, and the majority of severe cases in children, are due to rotavirus. Other significant viral agents include adenovirus and astrovirus.

Risk factors include consumption of improperly prepared foods or contaminated water and travel or residence in areas of poor sanitation. It is also common for river swimmers to become infected during times of rain as a result of contaminated runoff water.
