JACKSONVILLE, Fla. – There have been eight cases of Legionnaires' disease this year in Duval County.
It's a form of pneumonia that's treatable but can be fatal.
A tip to News4Jax suggested Legionnaires’ disease is showing up in area health care facilities. After checking with area hospitals, that does not appear to be the case.
