Health authorities in Findlay, IL, are grappling with a difficult situation as they investigate an outbreak of Legionnaires' disease that affected three individuals. The Illinois Department of Public Health (IDPH) and the Shelby County Health Department, in collaboration with the Illinois Environmental Protection Agency (Illinois EPA), are at the forefront of this investigation.

Initiated on August 16, the investigation revolves around three cases of the severe lung infection, Legionnaires' disease. The affected individuals, all residents of Findlay, reported symptoms between July 30 and August 4. Despite rigorous testing on water and swab samples taken from potential sources of exposure, the elusive Legionella pneumophila responsible for the illnesses was not detected.

Steve Melega, Administrator for the Shelby County Health Department says no new cases have been reported since the first three. Also noting that the water in Findlay is safe to drink. Melega says Legionella is known for spreading through water vapor.

Authorities noted that determining a definitive source of Legionella through environmental assessment is a rarity. The Illinois EPA's evaluation of the public water supply on August 11 found chlorine levels, crucial for Legionella disinfection, to be within safe limits. Ongoing sampling for chlorine residuals has been requested to ensure water safety.

Legionnaires' disease spreads through inhaling Legionella-contaminated water vapor, typically associated with complex water systems in places like hotels and hospitals. While healthy individuals are less susceptible, those aged 50 or above, smokers, people with chronic illnesses, and those with weakened immune systems face greater risk.

In 2022, Illinois reported 381 cases of Legionnaires' disease, with 237 confirmed cases in 2023 so far.
