CHICAGO (Chicago Sun-Times) — Health officials say two new cases of Legionnaires’ disease have been reported at a suburban Chicago senior living center, bringing the outbreak’s total cases to five, including one previous fatal case.

The Lake County Health Department said Tuesday that it’s working with the Illinois Department of Public Health to investigate the five cases of the disease at Brookdale Senior Living in Vernon Hills.

The health department had said Feb. 5 that one person who was over the age of 80 had died and that two other residents at the senior living center had been sickened by the disease.
