Legionnaires' Disease on Rise
The Association of Water Technologies (AWT), McClean, Va., released its newest paper on Legionella and minimizing the risk of legionellosis from water systems. The number of cases of legionellosis reported to the federal Centers for Disease Control and Prevention this year totaled 624 as of the beginning of July, compared to 436 for the corresponding period last year -- a 43 percent increase. In some regions of the country, the numbers are double or triple those reported at this time last year.
To help shed some light on the disease and its causes, AWT's paper "Legionella 2003: An Update and Statement by AWT," provides an overview of Legionella and Legionnaires' disease, including information such as:
- Background and general facts (history, susceptibility, disease symptoms).
- Potential sources of the disease, which can include cooling towers and evaporative condensers.
- How it is transmitted (inhalation or aspiration of contaminated water).
- How it can be tested and treated in water systems.
The paper is available as a free download from AWT's web site at www.awt.org/ Legionella03.pdf and was presented at the 2003 AWT Water Technologies Convention and Expo in Phoenix in September.
