This list below shows the current accommodation sites in EU/EEA countries with which clusters of Legionnaires’ disease have been identified but where the European Legionnaires’ disease Surveillance Network (ELDSNet) is unable to assess the risk of Legionella infection, or where ELDSNet believe there may be increased risk to travellers.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis B. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis B.
