Course Objectives
The widespread environmental contamination and growth of legionellae in water systems and associated equipment, in both public and private buildings, represents a health risk for those exposed. Buildings which pose a significant risk, if adequate controls are not in place, include particularly tourist accommodation, spa and health facilities. The problem can and needs to be faced by appropriate identification of risk and effective preventive and control strategies, as detailed in the recent revision of the European guidelines.
The main objective of the course is to increase the theoretical and practical knowledge and update on how to minimise the contamination and colonisation of water systems by Legionella. Risk assessment of systems and surveillance,
including investigations into potential sources of environmental contamination, before and after the appearance of single cases/clusters will be detailed. Clinical characteristic and diagnostic tests for detection of Legionella pneumonia will be examined. Preventive measures and strategies taking into consideration both the susceptibility of persons and environmental factors will be presented, together with new and traditional disinfection evidence based systems. Practical examples and exercises will be studied by small groups of participants.
Younger participants aiming to reach a skilled expertise for future employment in the sector are warmly invited to participate. The course aims also to expand cross working relationships and increase communication to improve the collaboration between the different professionals working in Legionella management, including clinicians, persons responsible for buildings, public health operators, researchers and persons involved in installation and maintenance of water and air distribution systems.
