Stomach Flu Symptoms & Diagnosis

Symptoms

If you have any of these do not assume it is due to norovirus. These may be caused by other, less serious health conditions. If you have any one these symptoms, see your doctor:

• Nausea
• Vomiting
  • An infected person may vomit often (sometimes violently and without warning) during one day.
• Diarrhea
• Abdominal pain
• Headache
• Low-grade fever
• Chills
• Muscle aches
• Tiredness
• Dehydration
  • This may require medical attention, especially in children, the elderly, and those with compromised immune systems
  • Prevent dehydration by drinking a lot of fluids, including water and juice

After exposure to the virus, symptoms often appear within 24-48 hours. You may feel ill as early as 12 hours. Symptoms often last about 24-60 hours.

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.

Diagnosis can be made based on a stool specimen. Often, your doctor can determine this illness without ordering any lab tests.
