ORLANDO (AP) -- Health officials have identified a fourth case of Legionnaire's disease in central Florida.

Orange County's health department says all four people diagnosed with the potentially fatal respiratory illness had stayed at a Quality Suites hotel in Orlando in late February or early March.

The medical status of the new patient identified Friday is not known. The health department says two other people are recovering after being released from the hospital, but a third is hospitalized.

The disease is caused by an organism that occurs naturally in water. Symptoms include headaches, loss of appetite, aches, pains, fever and coughing. It cannot be spread from person to person.

The department has cleared the hotel of any problems.
