Symptoms
By Mayo Clinic staffA rotavirus infection usually starts with a fever, followed by three to eight days of watery diarrhea and vomiting. 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 or lightheadedness
