Historical Headlines Related to Legionella

August 5, 2022

Marion County Health Department has been inspecting hundreds of pools this summer to prevent illness. These public pool illnesses includ Legionnaires' disease. The MCPHD inspects more than 900 private and public pools year-round. “We do close pools daily, unfortunately. It is not common, but it is about 10% of the time," said pool specialist Michael Furnas, who tests pH levels and disinfectant concentration, like chlorine and bromine. "So, every day, unfortunately, I have to close about one pool in the county or issue an emergency notice, a violation which is a warning where we allow them to self-close and fix the issues. Then, we recheck in the following days." (Source)

IDOC (Indiana Department of Correction) issued an update about the outbreak at the Pendleton Correctional Facility. IDOC stated that it properly responded to the outbreak: “IDOC also took immediate steps to limit further exposure to the bacteria for both staff and incarcerated individuals by installing point of use filters on shower heads within the facility, which provide a barrier against waterborne contaminants, including Legionella bacteria, allowing the incarcerated population to shower safely."
