At least 300 people have fallen ill in a large outbreak of stomach flu that has hit students and staff in Sollentuna. Food preparation kitchens are suspected.

There is a likely connection to the cooking kitchen in Häggvik School, says Elisabeth Thelin, Director of Administration in the environmental and planning office in the municipality of Sollentuna.

The municipality cooperates with the Infectious Diseases Stockholm to stop the spread of infection and find out what has caused stomach illness outbreak. Among other things, the kitchen cleaned and samples taken.

An investigation is underway. Yet we do not know what is the cause and it is important not to speculate, says Elisabeth Thelin.
