BBC News reports that two girls who attended a dance camp in Pembrokeshire have contracted E.coli, it has been confirmed.

An 11-year-old from the West Midlands is being treated in hospital and a seven-year-old from Denbighshire is recovering at home.

Both had attended Dance Camp Wales in Cresselly, which runs between 29 July and 9 August.

Social networking website Facebook is being used to try to contact about 650 people who attended a dance camp after two girls contracted E.coli.

Environmental health officials are also sending letters, e-mails and phoning, where they have contact details.
