Please see below for a final update on the Legionella Outbreak Response in Marshall County.

This was a difficult time for our community but especially for the individuals and families who were directly impacted by legionella. To those that lost loved ones we want to express our deepest condolences.

We want to extend a sincere thank you to our community for their understanding and cooperation during this outbreak response. From the swift action of the business centers to the vital support from local healthcare providers, community partners, Iowa HHS, the State Hygienic Laboratory, and the CDC—this response was truly a collective effort.

⚠️ Legionella Update ⚠️

Second Death Linked to Legionella

The Iowa Department of Health and Human Services (HHS) is reporting a second death associated with the Legionella outbreak in Marshalltown. The individual, an elderly adult with multiple underlying health conditions, passed away on September 18. To date, there have been 71 cases of legionellosis, including two deaths.

All available evidence continues to indicate cooling towers are the most likely source of the outbreak, although laboratory testing has not confirmed a direct source. Each business center with a cooling tower in the affected area has completed disinfection.

“We are encouraged to see fewer new cases reported recently,” said Dr. Robert Kruse, State Medical Director. “Our teams remain engaged with building owners on disinfection and it will take additional time to know if this decline reflects successful remediation.”

Individuals who live, work, or have spent time in north central Marshalltown with a cough, fever, or other symptoms of pneumonia should see their health care provider and ask about Legionella. The Marshall County Health Department, Iowa HHS, and the CDC continue to investigate all possible sources while working with business centers on remediation and prevention efforts.
