Legionnaires’ disease is a multisystem disease which causes pneumonia due to gram-negative bacteria (Legionella spp.) found in freshwater environments around the world. Humans are infected by inhalation of aerosols containing Legionella. The infection can be fatal and outbreaks from a common environmental source can occur. Cases of Legionnaires’ disease are mainly reported in persons in older age groups, especially in males.
The European Legionnaires’ disease Surveillance Network (ELDSNet) carries out European surveillance of Legionnaires' disease in Europe and is coordinated by the European Centre for Disease Prevention and Control (ECDC). All EU Member States, and Iceland and Norway, participate in the network. The members of ELDSNet are epidemiologists or microbiologists nominated by the national public health authorities. ELDSNet also collaborates with partners, such as World Health Organisation (WHO), public health authorities of countries and tour operators. Read more about ELDSNet
