Gasteroenteritis: Viral gastroenteritis is an intestinal infection caused by several viruses

Gasteroenteritis:

Viral gastroenteritis is an intestinal infection caused by several viruses. Viral gastroenteritis is highly contagious and causes millions of cases of diarrhea each year.

Anyone can get viral gastroenteritis. Most people recover from gastroenteritis without any complications. However, viral gastroenteritis can be serious for people who cannot drink enough fluids to replace what is lost through vomiting and diarrhea, especially infants, young children, the elderly, and people with weak immune systems. Complications from vomiting also can occur, even in healthy people.

Symptoms of Gastroenteritis
The main symptoms of viral gastroenteritis are watery diarrhea and vomiting. Other symptoms of gastroenteritis include headache, fever, chills, and abdominal pain. The symptoms may appear within hours or a few days of infection. They usually last for 1 to 2 days, but may last as long as 10 days.

Causes of Gastroenteritis
The viruses that cause viral gastroenteritis damage the cells in the lining of the small intestine. As a result, fluids leak from the cells into the intestine and produce watery diarrhea. Four types of viruses cause most viral gastroenteritis.

Rotavirus

Adenovirus

Caliciviruses

Astrovirus.

Viral gastroenteritis is often mistakenly called "stomach flu," but it is not caused by the influenza virus and it does not infect the stomach.
