A rotavirus infection usually starts with a fever and vomiting, followed by three to eight days of watery diarrhea. The infection can cause abdominal pain as well. In adults who are otherwise healthy, a rotavirus infection may cause only mild signs and symptoms — or none at all.

When to see a doctor

Call your child's doctor if your child:

  • Has severe or bloody diarrhea
  • Has frequent episodes of vomiting for more than three hours
  • Has a temperature of 103 F (39.4 C) or higher
  • Seems lethargic, irritable or in pain
  • Has signs or symptoms of dehydration — dry mouth, crying without tears, little or no urination, unusual sleepiness or unresponsiveness

If you're an adult, call your doctor if you:

  • Aren't able to keep liquids down for 24 hours
  • Have frequent episodes of vomiting for more than one or two days
  • Vomit blood
  • Have blood in your bowel movements
  • Have a temperature higher than 103 F (39.4 C)
  • Have signs or symptoms of dehydration — excessive thirst, dry mouth, little or no urination, severe weakness, dizziness on standing or lightheadedness
