Many Norovirus Infections at the Start of the Year in the North - Norovirus outbreaks spike in Schleswig-Holstein as cases surge in early 2026

Norovirus cases have surged in Schleswig-Holstein at the start of 2026. Health officials reported 482 infections in the first five weeks alone—a sharp rise compared to just 307 cases in the same period last year. The highly contagious virus continues to spread rapidly in group settings like schools and care homes.

The recent spike follows a broader trend of fluctuating norovirus activity. In 2025, Schleswig-Holstein recorded 2,285 cases, slightly fewer than the 2,367 infections in 2024. However, the virus remains a persistent threat, particularly in regions like Thüringen, where around 7,400 cases were logged for the entire year.

During the coronavirus pandemic, reported norovirus infections plummeted, dropping below 1,000 annually between 2020 and 2022. Health experts attribute this decline to stricter hygiene measures at the time. Now, with restrictions lifted, outbreaks have returned, especially in places where people gather closely.

Norovirus spreads easily through contaminated surfaces, food, or direct contact. Symptoms include severe vomiting, diarrhoea, and nausea, hitting young children and the elderly hardest. Since no vaccine exists, prevention relies on basic hygiene. The AOK health insurer stresses thorough handwashing with soap as the best defence. Infected individuals should also isolate for at least two days after symptoms fade to avoid passing on the virus.

The latest figures highlight norovirus as an ongoing public health challenge. With cases climbing in multiple states, hygiene remains the key tool for control. Officials urge vigilance, especially in high-risk settings like daycare centres and hospitals.
