This outbreak investigation also highlights the need for ongoing health care provider education regarding the importance of obtaining clinical isolates for public health legionellosis
Taken together, these data suggest that for future outbreak investigations, extensive sampling of environmental samples may be required to identify genotypes responsible for episodes of legionellosis
infection, if indeed they are present.

During 2000-2011, passive surveillance for legionellosis
in the United States demonstrated a 249% increase in crude incidence, although little was known about the clinical course and method of diagnosis," said the report, whose principal author was Dr.
The 20 states and one large metropolitan area ([section]) that reported [greater than or equal to] 90% of confirmed NNDSS legionellosis

ANSI/ASHRAE Standard 188-2015, Legionellosis
: Risk Managementfor Building Water Systems, (4) is the first United States standard to establish the minimum legionellosis
risk management requirements for building water systems at risk for Legionnaires' disease outbreaks.
Ashbolt (2009) describes legionellosis
as the single largest cause of waterborne disease in the U.
Randomized controlled trials comparing the efficacy of these strategies are lacking, but the availability of guidance for using waterborne pathogen prevention and control strategies has resulted in substantial declines in health care-associated legionellosis
5) The current overall incidence of legionellosis
is difficult to ascertain and likely under-represented in the literature which estimates that there are 25,000 cases annually in the US.
Meridian Bioscience Inc (NASDAQ: VIVO) revealed on Monday the receipt of clearance from the US Food and Drug Administration (FDA) for a new rapid assay for detection of legionellosis
