The burden of hospital-acquired legionellosis in German teaching hospitals

Legionella pneumophila is a recognized cause of hospital-acquired pneumonia particularly in immunocompromised patients. Significant resources are dedicated to the monitoring and control of Legionella contamination in hospital water systems. However, the actual risk of nosocomial Legionella infection...

Description
Summary:Legionella pneumophila is a recognized cause of hospital-acquired pneumonia particularly in immunocompromised patients. Significant resources are dedicated to the monitoring and control of Legionella contamination in hospital water systems. However, the actual risk of nosocomial Legionella infections in German university hospitals, which represent large tertiary care institutions, remains poorly defined. The aim of this study was to quantify the incidence of nosocomial legionellosis in German university hospitals. In addition, the extent of routine testing of hospital drinking water systems and preventive measures implemented on legal grounds was investigated.
