Norovirus Cases Surge Across the U.S. This Winter
Outbreaks have reached the highest levels in over a decade, with health officials emphasizing prevention and hydration as key strategies.
- The CDC reported 91 norovirus outbreaks in early December 2024, the highest number for that week since 2012, with cases expected to peak in mid-January 2025.
- Norovirus symptoms include sudden onset of vomiting, diarrhea, nausea, and stomach pain, with most cases resolving within 1 to 3 days.
- The virus spreads easily through contaminated food, water, surfaces, and direct contact, remaining contagious for up to two weeks after symptoms subside.
- Health experts stress thorough handwashing with soap and water, as alcohol-based sanitizers are ineffective against norovirus, and recommend disinfecting surfaces with bleach-based cleaners.
- Severe dehydration poses risks for vulnerable groups like young children, the elderly, and immunocompromised individuals, with hydration being the primary treatment focus.
