Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Tens of thousands of people contract Legionnaires' disease each year, 5 to 30% of whom die from it within a few days. You can get the disease while showering, brushing your teeth, drinking water, washing your face, bathing in a hot tub, or walking by a decorative fountain. Legionnaires' disease is not rare. People just think it's rare because over 90% of the cases go undetected. Many deaths attributed to pneumonia are actually caused by Legionella bacteria. In simple language, Legionella expert Matt Freije explains how to avoid the disease in public places-for example, in hospitals, office buildings, and hotels-and how to reduce your risk at work, at the dentist, and from various types of equipment like misters, cooling towers, decorative fountains, hot tubs, and whirlpool bathtubs. The book starts with facts you need to know about Legionnaires' disease: causes, symptoms, susceptibility, death rate, diagnosis, undetected cases. The survivor stories in chapter 2 will make you realize how horrible the disease is, and that it can affect anyone. The last chapter tells how to avoid the disease at home. Advice is given about faucets and showers, water heaters, softeners, filters, humidifiers, and home construction.

Legionnaires' Disease : The Control of Legionella Bacteria in Water Systems

Drawn from ASM′s 1992 symposium on the subject, this book completely updates information on all aspects of Legionella and Legionnaires disease. Strategy sessions held at the symposium to address current issues involving preventive measures to minimize the presence of Legionella and occurence of Legionnaires disease, the evolution of chemotherapy and diagnostic tests, and prospects for vaccine development are summarized. Legionella is required reading for anyone working in this area of infectious disease. As the sole source of current knowledge and theory on Legionella, it is an extremely useful reference for clinical microbiologists, environmental microbiologists, epidemiologists, infectious disease and other clinical specialists, and environmental engineers.

These checklists were developed to accompany a video on the subject of Legionnaire's disease (SB: 10700). They are designed to be used by the responsible person to audit arrangements in place in premises to control legionella in water systems. The checklists are intended to audit the risk assessment process and take the responsible person through the recommended measures in the Approved Code of Practice and guidance on the control of legionella bacteria in water systems, so they can audit the arrangements in place. They do not give guidance but are intended to supplement the guidance available. A copy of the checklists will accompany the video. They are also available in priced packs.
