Norovirus Cases on the Rise: Key Facts and Prevention Tips
The US Centers for Disease Control and Prevention (CDC) has reported a surge in norovirus cases, with 91 outbreaks recorded during the week of December 5, compared to 69 the previous week. This increase highlights the need for public awareness about this highly contagious virus, which is a leading cause of foodborne illness in the US.
What Is Norovirus?
Norovirus, also known as the winter vomiting bug, causes gastroenteritis with symptoms such as nausea, vomiting, diarrhea, and stomach cramps. It is responsible for 19-21 million cases annually in the US, leading to over 465,000 emergency visits and 109,000 hospitalizations. It spreads easily through direct contact with infected individuals, contaminated surfaces, or shared food and utensils.

Symptoms and When to Seek Medical Attention
Symptoms typically appear suddenly and last 1-2 days. While most people recover without complications, dehydration is a significant risk, especially for vulnerable groups like young children, the elderly, and those with underlying health conditions. Seek medical advice if symptoms persist, dehydration becomes severe, or unusual signs like blood in stool or high fever occur.
Prevention and Food Safety Tips
- Hand Hygiene: Wash hands with soap and water frequently, especially before eating or after using the bathroom.
- Avoid Preparing Food: Those experiencing symptoms should not handle food or utensils for at least 48 hours after symptoms subside.
- Clean Surfaces: Use bleach-based solutions to disinfect surfaces that may be contaminated.
- Proper Cooking: Avoid raw or undercooked meats, use a food thermometer to ensure proper cooking temperatures, and wash fruits and vegetables thoroughly.
- Separate Foods: Keep raw meats separate from ready-to-eat items to prevent cross-contamination.
Key Takeaways
Norovirus is highly transmissible but preventable with good hygiene and food safety practices. If you or someone in your household shows symptoms, take precautions to prevent spreading the virus to others. With increased vigilance, we can minimize the impact of norovirus and other foodborne illnesses.
