For most people, norovirus infection clears up within a few days and isn't life-threatening. But in some people — especially children and older immunocompromised adults in hospitals or nursing homes — norovirus infection can cause severe dehydration, malnutrition and even death.

Warning signs of dehydration include:

  • Fatigue
  • Dry mouth and throat
  • Listlessness
  • Dizziness
  • Decreased urine output
