Symptoms Of Norovirus

Norovirus, which is contagious, is an infection that brings about sudden diarrhea and vomiting. Often spread through contaminated food or water, norovirus can also be passed from person to person when in a confined area with an infected person. After being exposed to the virus, gastrointestinal symptoms will come on within twelve to forty-eight hours. It usually takes about three days for symptoms to go away. It may be a few more days after that before a person is feeling completely better. For the most part, norovirus isn’t a very dangerous illness, though it can cause complications in the very young and the very old.
