My daughter “suddenly turned white and projectile vomited all over her bedroom” after being struck with norovirus this week.

She was one of more than 200 pupils and 15 staff members sickened at a Primrose Hill school.

The London Evening Standard reports health types concluded norovirus was present at North Bridge House Preparatory School. The building in Gloucester Avenue was being cleansed today amid fears the virus could spread to the school’s other buildings.

In a letter sent to parents, headteacher Brodie Bibby said the school was “afflicted by a particularly unpleasant virus.”
