Key Insights
You are most contagious when you have symptoms of norovirus illness or during the few days after you feel better. You can continue to shed virus in your stool for several weeks after recovery. This shedding can last weeks to months if you have another medical condition. Some people with norovirus infection may show no signs or symptoms. However, they're still contagious and can spread the virus to others.

Norovirus, also known as the stomach flu, can be contagious for longer than you have symptoms. Find out how long you need to stay home when you have a stomach bug. There is a short lag or incubation period (up to two days) between the time that people acquire the virus and the time they get symptoms. People may be contagious during this period. Understanding how long you remain contagious with norovirus is crucial for preventing its spread. Typically, individuals infected with norovirus are most contagious during the first few days of illness and can remain so for up to 48 hours after symptoms subside.
People who have norovirus are most contagious when they have symptoms, like vomiting and diarrhea. But people are still very contagious up to 3 days after their symptoms go away. After that, people are less likely to spread the virus. But that doesnโt mean they're in the clear.
