Warning over school illness.
As many as 30 pupils at Clifton Primary School, in Balsall Heath, are believed to have been affected by the infection, a parent claimed. It follows three confirmed cases at Moor Green Primary School, in Moseley, a month ago.
The condition, unrelated to foot and mouth disease in animals, is a mild illness with symptoms including blisters and ulcers and is common in children under the age of ten.
Chris Bentley, Health Protection Agency spokesman for the West Midlands, said: "We have been made aware of the Clifton Primary hand, foot and mouth cases, but it is not routine to notify us of this condition."
