The trust has a 'no stars' rating

It follows disinfection and testing at the Royal United Hospital in Bath.

The hospital has worked with the Health Protection Agency, the Health and Safety Executive and environmental experts to get the all clear.

Chief executive Mark Davies has offered his condolences to the family of the victim, who died in February, and has apologised for any distress.

The disease, which is caused by water-borne bacteria, is thought to have spread from a contaminated shower head at the hospital.

The hospital trust, which has a "no stars" rating in the NHS's league tables, said the case was an isolated one.

Legionnaires' disease, also known as legionellosis, is a rare form of pneumonia that contaminates water supplies and is fatal in 5-15% of cases.
