Seven more people have been diagnosed with E coli following an outbreak at a primary school – while staff prepare to re-open for classes next week.

Eleven people from Feltham Hill Infant and Nursery School, in Bedfont Road, Feltham, have been confirmed with the bug – along with one pupil from the nearby Feltham Hill Junior School.

Parents criticised the Health Protection Agency (HPA) for not closing the junior school – which is on the same site – after it shut the infant school on February 3.

A spokeswoman for the HPA said: “This junior school pupil was excluded from school on February 3 when a sibling had symptoms. There is no case of onward transmission at the school.”

Parents were asked to destroy any exercise books that have been at home since January, and throw away all water bottles and book bags.
