Water Testing Results Reveal the Presence of Legionella Bacteria at Allegria Village Retirement Community Following Reports of Two Deaths

Posted in Legionnaire's disease,Our Blog,Outbreaks & Recalls on August 10, 2025

The Allegria Village retirement community is the subject of a cooperative public health investigation between local, state, and federal partners following reports of two Legionnaires’-related deaths. Another non-fatal case from last summer is being revisited as well.

How was this cluster of illnesses discovered? What is Legionnaire’s disease, and how bad is it? How do you know if you have Legionnaires’ disease? Follow along for this, and more as we dig into this Legionnaires’ disease cluster at this Allegria Village retirement community.

What We Know About the Allegria Village Retirement Community Legionnaires’ Disease Cluster So Far

Wayne County health officials launched an investigation at Allegria Village retirement community following reports of two Legionnaires’ disease deaths. When the second reported death involved another resident of Allegria Village retirement community, local health officials were concerned.

After a little digging, another Legionnaires’ disease case from last August came to light. This, non-fatal Legionnaires’ disease case may be an indication of a long-term problems at the facility.

Water Testing Revealed the Presence of Legionella Bacteria at Allegria Village

Residents indicated that Allegria Village administrators explained that the Legionella contamination was confined to a single building.

In a statement by chief medical officer Dr. Avani Sheth, Wayne County Health Human, and Veterans Services says, “testing of the affected area’s water system has detected the presence of Legionella bacteria, the organism that causes Legionnaires’ disease.

Common Human-Made Water Systems at Risk for Spreading Legionella Bacteria

  • Hot tubs
  • Hot water tanks and heaters
  • Showerheads and sink faucets
  • Decorative fountains and water features
  • Large, complex plumbing systems
  • Plumbing systems under construction or with dead legs
  • Cooling towers such as those used in large buildings air-cooling systems or industrial processes

Most cases of Legionnaires’ disease involve hot tubs and cooling towers.

What Is Legionnaires’ Disease and How Do You Get It?

Legionnaires’ disease is a Legionella bacterial infection that affects the lungs. You get Legionnaires’ disease by inhaling those microscopic bacteria that are suspended in aerosolized water droplets from a contaminated water source.

These bacteria naturally live in freshwater environments (lakes, streams, etc.). But they can also grow in human-made water systems.

Certain human-made water systems are better suited for growing and spreading harmful Legionella bacteria than others. Those that create a mist or hold stagnant water rank higher on the list.

Human-Made Water Systems Can Spread Legionnaires’ Disease

Most cases of Legionnaires’ disease involve hot tubs and cooling towers.

Even more rare, but possible, people may become infected by drinking water contaminated with Legionella bacteria if it accidentally reaches someone’s lungs after it is swallowed. This happens when water “goes down the wrong hole” or in cases of near drowning.

Common fixtures/systems that spread Legionella bacteria

  • Hot tubs
  • Humidifiers
  • Water hoses
  • CPAP machines
  • Hot water tanks and heaters
  • Showerheads and sink faucets
  • Decorative fountains and water features
  • Large, complex plumbing systems
  • Plumbing systems under construction or with dead legs
  • Cooling towers such as those used in large buildings air-cooling systems or industrial processes

Can I Get Legionnaires’ Disease from Being Near Someone Who Is Already Sick?

Fortunately, Legionnaires’ disease is NOT contagious. Unlike other respiratory infections, Legionnaires’ disease is not spread from person-to-person. This type of transmission is extremely rare.

Nearly all cases of Legionnaires’ disease link back to contaminated water systems.

What is Being Done About This Deadly Contamination?

Dr. Sheth explains that the county is now “supporting Allegria Village as they work to implement immediate response efforts, including disinfection and remediation of affected areas, temporary water restrictions and provisions of alternative water sources where necessary, ongoing environmental testing to ensure effectiveness of remediation efforts, and education residents and staff on seeking prompt medical evaluation if they develop symptoms.”

Risk Factors Increase in This Type of Facility

Allegria Village is a 55+ retirement and assisted living facility. Residents in this type of facility have increased risk factors for Legionnaires’ disease.

Not everyone exposed to Legionella bacteria become sick. But certain people are more likely to become sick if exposed, and experience more serious illness if infected.

Those at higher risk include:

  • People 50 years or older
  • Current or former smokers
  • People with chronic lung disease like chronic obstructive pulmonary disease (COPD) or emphysema
  • People with weak immune systems or who take drugs that weaken the immune system (such as after a transplant operation or chemotherapy).
  • People with underlying illnesses such as diabetes, kidney failure, or liver failure.
  • People with cancer

All potential conditions those in this demographic may have. Making preventions measure in the community more important than ever.

Symptoms to Look Out for If You Have Stayed, Visited, or Worked at Allegria Village Retirement Community

If you have stayed, visited, or worked at Allegria Village retirement community, look out for the following symptoms:

  • Cough
  • Shortness of breath
  • Fever
  • Muscle aches
  • Headaches

These symptoms usually begin around 2 to 14 days after exposure. However, in some cases, illness may take longer to present.

Other symptoms may include diarrhea, nausea, and/or confusion.

There is no vaccine to prevent Legionnaires’ disease, and prior infection does not contribute to future immunity.

Legionnaires’ Disease Can Be Deadly

Legionnaires’ disease symptoms should be taken very seriously.

Statistically, 1 in 10 individuals with Legionnaires’ disease will die from complication of their illness. In a health care setting like this, this risk elevates to 1 in 4.

That is a 25% mortality rate.

Outcomes are significantly improved with early, targeted treatment. So prompt diagnosis is important.

Most people with Legionnaires’ disease are never diagnosed with this illness. This is because symptoms of Legionnaires’ disease are very similar to other types of pneumonia illnesses. In fact, Legionnaires’ disease is often indistinguishable from regular pneumonia, even on a chest x-ray.

Specialized tests are required for an accurate diagnosis.
