Summary
Introduction:
This text discusses the results of an analysis of waterborne disease outbreaks associated with drinking water and other nonrecreational water in the United States during 2009-2010. The analysis was conducted by the Waterborne Disease and Outbreak Surveillance System and includes data from all states and territories.
Key Points:
* During 2009-2010, there were 33 drinking water-associated outbreaks resulting in 1,040 cases of illness, 85 hospitalizations, and nine deaths.
* The most commonly identified outbreak deficiencies were Legionella in plumbing systems (57.6%), untreated ground water (24.2%), and distribution system deficiencies (12.1%).
* In addition to the drinking water outbreaks, there were 12 outbreaks associated with other nonrecreational water, resulting in 234 cases of illness, 51 hospitalizations, and six deaths.
* Legionella was the most common etiology among both drinking water and other nonrecreational water outbreaks.
* The majority of outbreaks (75.8%) and most illnesses (79.4%) were linked to community water systems.
* The majority of outbreaks (51.5%) and most ill persons (93.7%) were associated with ground water sources.
* The most commonly identified setting was a community/municipality (45.5%).
Main Message:
The results of this analysis highlight the importance of addressing deficiencies in drinking water and other nonrecreational water systems to prevent waterborne disease outbreaks. The majority of outbreaks and illnesses were linked to community water systems and ground water sources, with Legionella being the most common etiology. Public health professionals can use this information to target prevention efforts against pathogens, infrastructure problems, and water sources associated with waterborne disease outbreaks.
