Noroviruses or Norwalk virus causes inflammation of the large intestine lining and the stomach, and considered as the main culprit of gastroenteritis in the U.S. Norwalk virus is named after the town of Norwalk, Ohio where the virus originated in 1972.
Norwalk virus or noroviruses are often called food poisoning as they can be transmitted though foods that have been contaminated with the virus. But, they are not always the result of food contamination. These viruses are also called stomach flu, but they are not influenza virus.
What Causes Norwalk Virus Infection?
Individuals can get infected with the virus if they drink fluids or eat foods that have been contaminated particularly raw fruits and vegetables, and raw or undercooked oysters. Individuals can also get infected with Norwalk virus if they touch their nose, eyes, and mouth after touching surfaces or objects that have been contaminated with the virus.

Vomiting and high fever are also significant to young children infected with the virus. The most common symptoms of Norwalk virus infection include:
