Rhode Island Hospital is taking precautionary measures to stop the spread of the water-borne bacterial disease legionella after two patients came down with it.
The hospital is investigating the source of the disease, and is using bottled water for drinking, instead of tap water, for hospitalized patients in potentially-affected areas. The hospital will also "superheat" and flush the water supply in those areas.
Legionella is a bacterial disease found in the natural environment, usually in warm water, and is a risk mainly to patients with compromised immune systems. It can cause a type of pneumonia commonly known as Legionnaires disease.
It is not transmitted person-to-person.
