Norovirus is one of the most common causes of viral gastroenteritis, often called the stomach flu. Despite the name, it’s unrelated to influenza. This highly contagious virus spreads easily through contaminated foods, surfaces, or direct contact with an infected person, and it can quickly lead to outbreaks in schools, workplaces, and healthcare settings. Adults infected with norovirus usually experience sudden vomiting, diarrhea, and stomach cramps, which can come on quickly and feel severe. While most people recover without medical treatment, understanding how long norovirus lasts and how to manage it safely is key to prevent the spread to others.

How Long Does Norovirus Last in Adults?
The typical duration of norovirus in adults is about 1 to 3 days. Symptoms usually start 12 to 48 hours after exposure and can include:
- Nausea and vomiting
- Diarrhea
- Abdominal cramps
- Mild fever and body aches
- Headache
- Fatigue and weakness
Although the illness is short-lived, the fatigue and loss of appetite can linger for several days afterward as your body recovers. However, adults can remain contagious even after symptoms stop. The virus can continue to shed in stool for up to 2 weeks after recovery, so maintaining good hygiene, especially handwashing, is essential during that time.
Factors That Can Affect Norovirus Recovery Time
While most healthy adults recover in a few days, some factors can influence how long norovirus lasts or how severe it can become:
- Age: Older adults may experience more prolonged or intense symptoms
- Immune System Health: Those with weakened immune systems may take longer to recover
- Hydration: Dehydration can delay recovery and make symptoms worse
- Rest & Nutrition: Getting adequate fluids and eating light, bland foods once vomiting subsides can help the body bounce back faster
If your symptoms persist beyond 3 days or worsen, it may indicate complications such as dehydration or another infection requiring medical evaluation.
How Long is Norovirus Contagious?
Norovirus is extremely contagious. You can spread it from the moment you start feeling sick and while you have symptoms. You can also spread this illness for up to 48 hours after symptoms end, and even potentially up to 2 weeks in your stool. That means even if you feel better, you could still infect others if proper hygiene isn’t followed. To reduce transmission, be sure to wash your hands thoroughly with soap and water. Clean and disinfect contaminated surfaces and wash laundry and bedding that may have come into contact with vomit or stool. Additionally, be sure to avoid preparing food for others for at least 2 days after symptoms end.
When To Visit Urgent Care
While norovirus typically clears on its own, urgent care can help if symptoms are severe or dehydration is a concern. Seek medical attention if you experience:
- Persistent vomiting or diarrhea for more than 2-3 days
- Signs of dehydration (dry mouth, dizziness, infrequent urination)
- Blood in stool or vomit
- High fever
- Inability to keep fluids down
At an urgent care center, medical providers can assess your condition and recommend treatment to help you recover quickly.
