Norovirus is a contagious virus that’s transmitted through:
- close contact with infected people
It causes unpleasant symptoms, such as:

Usually, norovirus passes within a couple of days, but in some cases, it can linger for a while.
Read on to find out how long this virus typically lasts, and when you should see a healthcare provider for your symptoms
Usually, norovirus isn’t life threatening, and you won’t need any type of treatment to recover.
However, some older adults, babies, or people with other health conditions can develop complications, such as severe dehydration, that require medical attention and can even lead to death.
Norovirus is highly contagious.
To help lower your chances of transmitting the virus to others:
- Wash your hands frequently, especially after using the bathroom.
- Avoid preparing food for others.
- Stay home from work while you’re sick.
- Don’t travel until you recover.
- Clean and disinfect surfaces.
- Wash laundry thoroughly in hot water.
- Wear rubber or disposable gloves when handling soiled items.
- Dispose of vomit and fecal matter in plastic bags.
- Avoid using public swimming pools.

You should see a healthcare provider if your symptoms are severe or don’t go away within a few days.
Also, signs of dehydration require a visit to your healthcare provider.
Signs may include:
- fatigue or lethargy
- dry mouth or throat
- decreased amounts of urine
Kids who are dehydrated might cry with few or no tears, or be unusually sleepy or cranky.
Antibiotics only work for bacterial infections, they’re not an effective treatment for norovirus.
Your healthcare provider will probably recommend rest and lots of fluids to prevent dehydration.
If you’re unable to drink enough liquids, you might need to receive them intravenously, or through an IV. Sometimes, healthcare providers will suggest an over-the-counter (OTC) anti-diarrheal medication.
If you get the norovirus, you can expect to feel bad for about 1 to 3 days. Some people may take longer to recover.
There’s no treatment for this virus. However, it’s important to see a healthcare provider immediately if your symptoms are severe or persistent. They can help to create a plan for managing your symptoms.
