Noroviruses

Noroviruses are a group of viruses that cause stomach illness. This illness is also called gastroenteritis or the "stomach flu." Noroviruses are not related to the flu (influenza).

You can get noroviruses through contact with infected people.

Prevention

You can prevent the spread of noroviruses by handwashing, cleaning, and avoiding contact with infected people. Contact can be through sharing eating utensils, changing diapers, consuming contaminated food or drinks, or touching infected surfaces or objects.

Always wash your hands with soap and water before eating or preparing food, and after using the bathroom or changing a diaper. Immediately clean up vomit and stool and anything they touch. If you are sick with a norovirus, stay home to avoid infecting others.

Symptoms

Symptoms start one to two days after infection with the virus. The most common are vomiting and diarrhea. Other symptoms include:

  • Nausea
  • Stomach cramps
  • Fever
  • Chills
  • Chills
  • Aches

Treatment

There is no specific treatment for norovirus and most people get better on their own. You can take medicine to reduce diarrhea and vomiting. You should also drink plenty of fluids to prevent dehydration. If you get dry skin, dry mouth, or dry eyes, go to a doctor or hospital immediately.
