Legionnaires’ Outbreak in Iowa: Your Legal Rights
A recent outbreak of Legionnaires’ disease in Marshall County, Iowa has left residents concerned and raises serious questions about when property owners will be held accountable. These cases require an experienced Legionnaires’ disease lawyer to investigate thoroughly and pursue justice against those responsible. Our firm has handled similar cases, including a landmark $3.8 million verdict against an international hotel chain, along with multiple other significant recoveries for clients who contracted the disease.
What’s Going on in Marshalltown
Marshall County has been managing an outbreak of Legionnaires’ disease that has already killed one person since it was first identified in August.
The Iowa Department of Health and Human Services confirmed that the outbreak began with 21 cases on Sept. 4. As of Sept. 16, 54 cases have now been reported.
State and county officials have identified 10 cooling towers in Marshalltown as potential sources of the outbreak. Testing is underway, and tower owners have been ordered to treat their systems to prevent further spread.
Public health experts note that Legionella testing takes weeks, since the bacteria grow slowly in lab cultures. Officials are being careful not to rush to assign blame until lab-confirmed matches link water samples to patient infections.
Cooling towers—large square units often seen on rooftops—cool hot water from industrial equipment or building HVAC systems. When not properly maintained, they provide the perfect environment for Legionella bacteria to grow.
Legionella thrives in water temperatures of 77 to 113°F, making improperly maintained towers and other water systems high-risk.
Understanding Legionnaires’ Disease
Legionnaires’ disease is a severe lung infection caused by the Legionella bacteria. It spreads when people inhale tiny water droplets containing the bacteria—often from:
Cooling towers
Hot tubs and spas
Decorative fountains
Large plumbing systems
It is not spread person-to-person. Symptoms include fever, cough, and shortness of breath. According to the CDC, about 1 in 10 people who get Legionnaires’ disease die, and survivors often face long-term health complications.
Why These Outbreaks Lead to Legal Claims
When people contract Legionnaires’ disease from a hotel, apartment, or commercial property, there are often grounds for legal claims. Liability typically turns on:
Duty of care — Owners/operators must maintain water systems safely.
Negligence — Failure to test, disinfect, or treat contaminated systems.
Causation — Linking exposure at a specific site to illness. Outbreaks with confirmed sources strengthen this.
Damages — Covering medical costs, long-term health problems, lost wages, and pain and suffering.
Our Case: $3.8 Million Verdict
In 2017, we represented a client who contracted Legionnaires’ disease while staying at a major international hotel chain during a business trip. Evidence showed the hotel failed to maintain its water systems properly.
We proved negligence, linked exposure to the hotel stay, and demonstrated the long-term harm our client suffered. The jury awarded a $3.8 million verdict, sending a strong message about the responsibility property owners bear to protect guests.
