Suspected vomiting virus sickens 4,000 German kids

BERLIN (AP) - German health authorities say at least 4,000 children have fallen ill with vomiting and diarrhoea after eating food from school canteens and daycare centers.

The Robert Koch-Institut says it was alerted to a sudden surge in gastroenteritis cases that began on Tuesday in Berlin and surrounding regions.

The institute said in a statement on Thursday that laboratory investigations are under way to determine the exact cause of the outbreak.

But it says all facilities where the illness occurred likely received food from a single supplier, indicating it was a food-borne illness such as norovirus, a common cause of food poisoning.
