Leaflet on noroviruses
Infections with noroviruses can occur year-round, with a seasonal peak occurring in the months of October through March.

Route of infection

Direct transmission from person to person is primarily the cause of the high number of norovirus infections. Infections can also come from contaminated food (salads, crabs, mussels, etc.) or drinks (contaminated water!). Transmission through contaminated objects or items is also possible.

Preventive and control measures

1. Preventive measures
A vaccination is not available. Consistent compliance with general hygiene rules in communal facilities and kitchens is important. To avoid transmission through contaminated food, seafood dishes in particular should be well cooked.

2. Measures for patients and contact persons
To avoid transmission through a faecal-oral route or when vomiting (contact with stool, vomit, contaminated surfaces), the following hygiene measures should be expanded, especially in the symptomatic phase: Isolation of sick people, if necessary cohort isolation / care, wearing gloves, protective gowns, if necessary suitable respiratory protection, consistent hand hygiene, hand disinfection, disinfection of surfaces near the patient, toilets, sinks, door handles.

Protection against infection
Not with every mask.
