Norovirus is one of the most contagious stomach viruses, known for causing sudden and severe vomiting, diarrhea, stomach cramps, and nausea. Often referred to as the “stomach flu” (though it is not related to influenza), norovirus spreads quickly and easily, making it a major cause of outbreaks in public spaces. In this blog, we’ll break down the timeline of norovirus contagiousness, how it spreads, and what you can do to prevent infecting others.

How Long Are You Contagious After Norovirus?
On average a person with norovirus can spread the virus from the moment symptoms begin until at least 48 hours after recovery. However, some individuals may still shed the virus for up to 2 weeks, making extra precautions necessary.
1. During Symptoms (Most Contagious Period)
The most contagious period is when you have symptoms, which usually last one to three days. Everything you touch during that time might have the virus on it — so wash your hands often, and keep away from other people.
2. Up To 48 Hours After Symptoms Stop
Even after you feel better, the virus doesn’t go away immediately. Most confer immunity only for about two months and norovirus can still be spread by most people for at least two days after symptoms resolve. Even without symptoms, some people continue shedding the virus for up to two weeks.
3. Up To 2 Weeks or More in Stool
In some cases, norovirus can continue to be shed in stool for up to 2 weeks (or longer) after symptoms stop. While the risk of spreading the virus decreases significantly after the first few days, it’s still possible to pass the virus to others during this extended period.
How to Prevent Norovirus Transmission
1. Wash Your Hands the Right Way: Soap and water are your best defense. Scrub for at least 20 seconds; especially after using the bathroom, or before handling food.
2. Disinfect Surfaces: Wipe down counters, toilets and doorknobs with a bleach-based cleaner. Wash towels, clothing and bedding in hot water if someone in your household is sick.
3. Avoid Cooking for Others: Even if you’re feeling better, you should remain out of the kitchen for at least 48 hours after symptoms resolve. Food contamination is one of the primary ways norovirus is transmitted — so let someone else cook.
4. Stay at Home Until You’re in the Clear: If possible, stay away from work, school and public places for at least 48 hours after your last symptoms. For others who work in restaurants, hospitals or childcare, staying home longer may be required to avert an outbreak.
When To Seek Medical Attention
Most cases of norovirus are self-limiting, though dehydration and complications can occur. Seek medical attention if you have:
- Severe dehydration (dark urine, dizziness, dry mouth)
- Vomiting or diarrhea that lasts more than 3 days
- A fever higher than 102°F
- Difficulty keeping fluids down
- Severe fatigue or confusion
