Norovirus Outbreaks Surge in Louisiana: Key Facts and Tips
LAFAYETTE, La. (KPEL News) - As winter settles in across Louisiana, health officials are sounding the alarm about a rise in norovirus cases. This highly contagious stomach virus is making its presence felt nationwide, and Louisiana residents are no exception.
Here’s what you need to know to keep yourself and your loved ones safe this season.

Understanding Norovirus: A Local Threat
Norovirus is the leading cause of foodborne illness in the United States, responsible for an estimated 19 to 21 million cases annually. The virus spreads easily, requiring as few as 10 particles to infect a person. Symptoms include sudden vomiting, diarrhea, nausea, and stomach pain, often accompanied by headache, body aches, and fever.
Louisiana’s communal lifestyle—from family gatherings to school events and crowded celebrations like Mardi Gras—provides an environment where the virus can quickly spread. This makes awareness and prevention particularly crucial for residents.
Norovirus Cases Rising in Louisiana
The U.S. Centers for Disease Control and Prevention (CDC) reports a sharp increase in outbreaks this season, with December figures far surpassing those of previous years. In the first week of December, 91 outbreaks were reported nationwide, up from 69 the week before. Louisiana’s community settings, including nursing homes, schools, and daycare centers, are especially vulnerable.
How Does Norovirus Spread?
The virus is primarily transmitted through:
- Direct contact with an infected person.
- Consuming contaminated food or water.
- Touching contaminated surfaces and then touching your mouth.
Confined spaces, such as cruise ships and dormitories, amplify the risk of outbreaks. With Louisiana’s many shared spaces and events, taking precautions is vital.
Protect Your Family from Norovirus
Here are some practical steps to reduce your risk:
Wash Your Hands: Use soap and warm water for at least 20 seconds, especially before eating or preparing food.
Disinfect Surfaces: Clean high-touch areas regularly with household disinfectants.
Avoid Contaminated Food: Ensure seafood and other foods are cooked thoroughly.
Stay Home When Sick: If you experience symptoms, avoid close contact with others until 48 hours after they subside.
Who Is Most at Risk?
While norovirus can affect anyone, certain groups are more vulnerable:
Young Children: Daycare environments often see rapid virus spread.
Older Adults: Residents of nursing homes are particularly susceptible.
People with Weakened Immune Systems: This group faces a higher risk of complications.
Dehydration, caused by vomiting and diarrhea, is the top concern. Watch for symptoms such as dry mouth, reduced urination, and dizziness. Seek medical attention if dehydration becomes severe.
What to Do If You Get Sick
Most cases of norovirus resolve within one to three days. To recover:
- Drink plenty of fluids to combat dehydration. Avoid coffee, tea, and alcohol.
- Rest and stay isolated to prevent spreading the virus.
- Monitor symptoms and seek medical care if they worsen.
Looking Ahead: Stay Vigilant This Winter
With Louisiana’s active social scene and family-focused culture, preventing norovirus requires community-wide effort. Stay informed, practice good hygiene, and encourage those around you to do the same.
