It’s the leading cause of acute gastroenteritis, responsible for countless sick days, school absences, and disrupted travel plans. While norovirus is most common in colder months, outbreaks can occur year-round in homes, schools, restaurants, cruise ships, and nursing facilities.
If you’re suddenly dealing with nausea, vomiting, or diarrhea, here’s everything you need to know about norovirus symptoms, prevention tips, and how BASS Medical Group can help.
What Is Norovirus?
Norovirus spreads quickly and easily—through contaminated food, water, surfaces, or close contact with an infected person. It only takes a small amount of the virus to get sick, and symptoms can start within 12 to 48 hours of exposure.
Quick Facts:
- Norovirus is not treated with antibiotics (which only work on bacteria).
- It can survive on surfaces for days and resist many household disinfectants.
- People remain contagious for several days after symptoms stop.
Common Norovirus Symptoms
You may feel fine one moment and suddenly feel very ill the next. That’s typical of norovirus. Most symptoms last 1 to 3 days.
Main Symptoms Include:
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramps or bloating
Other Possible Symptoms:
- Headache
- Muscle aches
- Chills
- Low-grade fever
- Sudden fatigue
- Loss of appetite or taste
Warning: Dehydration is the biggest concern, especially for infants, older adults, and those with chronic conditions. Watch for signs like dry mouth, reduced urination, dizziness, or dark urine.
When to See a Doctor
Most people recover from norovirus at home. However, you should schedule a visit with a BASS primary care provider if:
- Symptoms last more than 3 days
- You can’t keep fluids down
- Vomit appears green/yellow (bile) or contains blood
- You experience severe abdominal pain or a high fever

Norovirus Treatment Tips
There is no specific antiviral medication for norovirus. Treatment focuses on managing symptoms and preventing dehydration.
Recommended Home Care:
- Drink fluids frequently (water, Pedialyte, or diluted juice)
- Try the BRAT diet: Bananas, Rice, Applesauce, Toast
- Get rest—your body needs time to recover
- Avoid sugary, caffeinated, or alcoholic drinks
- Use electrolyte tablets or oral rehydration solutions if needed
In severe cases, IV fluids may be necessary. Contact your provider if dehydration symptoms worsen.

How to Prevent Norovirus from Spreading
- Wash your hands often with soap and warm water for at least 20 seconds.
- Clean surfaces using a bleach-based cleaner (5–25 tablespoons bleach per gallon of water, per CDC).
- Don’t prepare food for others while sick and for 48–72 hours after recovering.
- Disinfect shared items and laundry (especially bedding and towels).
- Thoroughly cook shellfish, especially oysters.
- Avoid contaminated foods and rinse fruits/vegetables before eating.
Bonus Tip: Wash your hands to the tune of "Jingle Bells"—it’s 20 seconds long and perfect during holiday season outbreaks.
