Norovirus

Norovirus

Noroviruses are a group of viruses that cause the “stomach flu,” or gastroenteritis (GAS-tro-en-ter-I-tis), in people. Norovirus is also commonly known as Norwalk or the “cruise ship disease.” Viruses are very different from bacteria and parasites. They are not affected by treatment with antibiotics, and they cannot grow outside of a person’s body. This illness is not the same as influenza, which is a respiratory illness.
