The fight against Legionnaires’ disease—a severe form of pneumonia caused by Legionella bacteria—is evolving. With rising global temperatures, aging infrastructure, and more complex building water systems, traditional detection methods are no longer enough. Thankfully, new Legionella detection technologies are reshaping how we manage this persistent public health threat, making detection faster, more accurate, and more…
When a Legionnaires’ disease outbreak is suspected, environmental sampling becomes one of the first and most important steps in identifying the source of contamination. This process involves collecting water and environmental samples from potential sources like cooling towers, plumbing systems, and hot tubs to detect the presence of Legionella bacteria. By pinpointing contaminated areas, environmental…
Imagine trying to stop a deadly outbreak with only a blurry picture of the suspect. For decades, that’s exactly how public health officials investigated Legionnaires’ disease. Traditional methods like pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) could offer clues, but rarely a clear match. As a result, only 38% of Legionnaires’ outbreak investigations using…
Legionella bacteria are a growing public health concern, especially in complex, aging, or poorly maintained plumbing systems. For building owners, engineers, facility managers, and legal professionals, understanding why Legionella thrives in certain environments is not just a technical matter; it’s a legal and public health priority. As recent outbreaks across the U.S. have shown, Legionnaires’…
