Because there are so many types of noroviruses, you can become infected and show symptoms many times. Symptoms of gastroenteritis caused by noroviruses can include:

  • Nausea
  • Abdominal cramps
  • Vomiting
  • Diarrhea
  • Headache
  • Fatigue
  • Fever
  • Muscle aches

Symptoms usually develop within hours or a few days after you are infected with a norovirus. It usually takes a couple of days before you are better.
