Annual Threat Report 2009

The Annual Threat Report describes how epidemic intelligence officers at ECDC responded to the 192 distinct threats monitored in 2009. The report covers 2009 threats such as legionellosis, Salmonella Goldcoast, verocytotoxin-producing Escherichia coli, mumps, measles, West Nile virus, Q fever and malaria. The influenza A(H1N1) pandemic features prominently: 88% of all message threads relayed through the Early Warning and Response System were related to pandemic influenza A(H1N1). Previously part of the ‘Annual Epidemiological Report on Communicable Diseases in Europe’, the new Threat Report is now published separately to ensure improved coverage of event-based disease surveillance
