Managers at the West Suffolk Hospital, Bury St Edmunds, have confirmed that NHS East of England had been alerted to a suspected death from swine flu.

Little is known about the case other than that it involves a man thought to be 40 years of age who was in good health prior to being taken into the Hardwick Lane hospital.
