In April of 2023, something alarming began to unfold in the quiet city of Grand Rapids, Minnesota, a Legionnaires’ disease outbreak that would stretch across 14 months.

By June 2024, 34 people had been diagnosed with this dangerous form of pneumonia caused by Legionella bacteria. The impact was serious—30 were hospitalized, and sadly, two individuals lost their lives.

Source Identified and Response Efforts

After months of rigorous investigation, the Minnesota Department of Health (MDH) pinpointed the culprit: the municipal water system.

Tests revealed Legionella bacteria in water samples from buildings in the affected zone, and DNA results confirmed the match to infected patients.

In response, chlorine disinfection began in June 2024, and since then, no new cases have been reported. According to MDH, the outbreak will be considered officially over if a full year passes with no additional linked infections.

Geographic Area of Concern

The outbreak was highly localized within a 1.6-square-mile zone. This area includes:

• North of Golf Course Rd/SE 10th St
  
• South of NE/NW 8th St
  
• East of 11th Ave SW/10th Ave NW
  
• West of 7th Ave SE/8th Ave NE

Residents and business owners in this zone are urged to stay informed and continue practicing safe water habits.

Public Health Recommendations and Water Safety

MDH recommends proactive water management to prevent future growth of Legionella.
Key tips include:

• Keep cold water cold (under 68°F)
  
• Keep hot water hot (above 120°F—while preventing scalding)
  
• Clean fixtures like showerheads and faucets regularly
  
• Keep water moving to avoid stagnation

Why it matters: Legionella loves warm, stagnant water conditions that were present in Grand Rapids, which hadn’t chlorinated its groundwater-based system prior to the outbreak.

Legal and Health Considerations

If you or a loved one was affected, you may have legal options. Those diagnosed with Legionnaires’ disease may be eligible for compensation, including medical costs, pain and suffering, and other damages. An experienced attorney can help assess liability and guide you through your options.

Contact and Next Steps

If you or someone you love was diagnosed with Legionnaires’ disease in Grand Rapids between April 2023 and June 2024, consult your healthcare provider and explore your legal rights. Prompt diagnosis and treatment are crucial for recovery, and taking preventive action now can protect your health and legal interests.
