Viral Gastroenteritis and Gastrointestinal Infection

Gastrointestinal infections are infections caused by viruses, bacteria, or parasites that cause gastroenteritis, an irritation of the gastrointestinal tract that includes both the stomach and the small intestine. Diarrhea, vomiting, and abdominal pain are among the symptoms. Because dehydration is the most common cause of gastrointestinal infections, rehydration is critical; however, most gastrointestinal infections are self-limiting and resolve within a few days. Viral gastroenteritis is an infection of the intestine that causes watery diarrhea, abdominal cramps, nausea or vomiting, and, in some cases, fever. The most common way to contract viral gastroenteritis, also known as stomach flu, is through contact with an infected person or by consuming contaminated food or water.
