Stomach flu (viral gastroenteritis): virtual care options
The stomach flu is an infection of the stomach and intestines, usually caused by a virus such as norovirus. Despite the name, it is not related to influenza. It spreads easily in households, schools, and cruise ships, and most people feel better within a few days.

Common questions
Stomach flu, answered.
General information, not medical advice. A provider can answer questions about your situation.
How long does the stomach flu last?
Most people start to feel better within one to three days, though tiredness can linger. If symptoms last longer or keep getting worse, check in with a provider.
Is the stomach flu contagious?
Yes. It spreads through contact with an infected person, contaminated food, or surfaces, and people can stay contagious for a few days after they feel better. Careful handwashing with soap and water helps limit spread.
Can I see a doctor online for the stomach flu?
Yes, a virtual visit can be a good fit when symptoms are mild to moderate and you can keep some fluids down. A provider can advise on hydration and may offer treatment if it is appropriate.
This is not for emergencies.
For life-threatening symptoms, severe chest pain, trouble breathing, or immediate danger, call 911 or go to the nearest emergency department.
