Welcome to the Legionnaires' disease outbreak investigation toolbox

The main objective of this site is to provide a series of practical tools that Member States, Iceland, Liechtenstein and Norway and ECDC can use to facilitate a co-ordinated investigation and response to clusters and outbreaks of Legionnaires' Disease with an EU dimension. The ECDC ELDSNet site contains additional information regarding the European Surveillance Network for Legionnaires' Disease and related resources. ELDSNet carries out surveillance of Legionnaires' disease and aims to identify relevant public health risks, enhance prevention of cases and monitor epidemiological trends. The European Working Group for Legionella Infections (EWGLI) website (http://www.ewgli.org/), also provides information on the epidemiological and microbiological aspects of the disease.

This toolbox also provides scientific information and references pertaining to Legionnaires' disease and legionella as a background resource.

Four options for navigation around this toolbox are provided:

• A process chart mapping key events and decisions points during an outbreak, with links to the relevant sections.
• A site map of the entire toolbox.
• Direct access to the downloadable tools.
• The blue chevrons in the margin lead to the relevant outbreak management theme.
