More than 50 aged-care residents have fallen ill with a stomach bug at a Hove nursing home. At least five staff were also hit by a virulent strain of the contagious norovirus over the Christmas period at the Alwyndor Aged Care centre run by the City of Holdfast Bay. SA Health is providing advice on infection control and dealing with victims. Alwyndor Aged Care general manager Rick Kluge said the home was struck by the virus in the lead-up to Christmas and 52 of the 134 aged residents fell ill between December 18 and 26.
