What is Norovirus?
- Norovirus is a very contagious virus that causes vomiting and diarrhea.
- It is sometimes called the “stomach flu” or the “stomach bug.” However, norovirus illness is not related to the flu. The flu is caused by the influenza virus. Norovirus causes acute gastroenteritis, an inflammation of the stomach or intestines.
- Most people with norovirus illness get better within 1 to 3 days; but they can still spread the virus for a few days after.
How to prevent Norovirus:
- Norovirus is very contagious, but you can take steps to stop it from spreading.
- Wash hands well with soap and water; hand sanitizer alone does not work well against norovirus.
- Clean and disinfect contaminated surfaces.
- Do not prepare, handle food, or care for others when you are sick.
- Stay home when sick for 48 hours after symptoms stop.
How does Norovirus spread?
Norovirus spreads very easily and quickly in different ways. You can get norovirus by:
- Having direct contact with someone with norovirus, like caring for them, sharing food or eating utensils with them, or eating food handled by them.
- Eating food or drinking liquids that are contaminated with norovirus.
- Touching contaminated objects or surfaces and then putting your unwashed fingers in your mouth.
You can still spread norovirus for 2 weeks or more after you feel better.
Signs and Symptoms:
A person usually develops symptoms 12 to 48 hours after being exposed to norovirus.
- Most common symptoms: Diarrhea, vomiting, nausea, stomach pain
- Other symptoms: Fever, headache, and body aches
Treatment and recovery
Most people with norovirus illness get better within 1 to 3 days. There is no specific medicine to treat people with norovirus illness. Antibiotic drugs will not help treat norovirus infections because they fight bacteria, not viruses.
- Drink plenty of liquids
- Seek medical care for severe dehydration
