A Norovirus outbreak has impacted a primary school in Bad Laer, Lower Saxony, with 144 children confirmed to be infected as of February 20, 2026. Laboratory analyses have also detected the virus in six teachers, according to the Landkreis Osnabrück.
In addition to the students, three other school staff members are experiencing typical gastrointestinal symptoms. A total of 227 children at the school are currently absent—more than two-thirds of the student body. Fifty-three students at a secondary school in the same town are also affected, a Landkreis spokesperson stated on Friday. Authorities are currently investigating the source of the outbreak.
Origin of the Virus is Still Unclear
The Landkreis stated that determining how the virus entered the school may not be possible. The school cafeteria is considered an unlikely source, as the food provider also serves other facilities without reported outbreaks. Despite the high number of cases, school operations are continuing, but the health department has announced measures to prevent further spread.
Hygiene Measures Remain Important
The school will undergo intensive cleaning. Students who are ill should remain home for at least 48 hours after their symptoms subside. Proper hygiene, especially after using the restroom, remains crucial, as the Norovirus can be shed in stool for weeks after the acute infection ends. The “Neue Osnabrücker Zeitung” first reported on the situation.
