This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 14-20 January 2018 and includes updates on influenza, yellow fever and salmonellosis.

This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 31 December 2017-6 January 2018 and includes updates on hepatitis A, influenza, MERS, poliomyelitis and salomnellosis.

The “Avian influenza overview” report is published quarterly and provide an update of the developments of avian influenza viruses in EU/EEA and worldwide, in particular with a view to describe the evolution of virus spread from certain regions towards the EU. In case of significant changes in the epidemiology of avian influenza, these reports could be needed more frequently.

The report is published jointly by the European Food Safety Authority (EFSA), the European Centre for Disease Prevention and Control (ECDC) and the European Union Reference Laboratory for Avian influenza (EURL). Avian influenza is an infectious viral disease in birds, including domestic poultry. Avian influenza is mainly found in birds, but under certain circumstances infections can also occur in humans even though the risk is generally very low.

This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 27 August - 2 September 2017 and includes updates on measles, MERS, West Nile fever and Chikungunya.

This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 9 July - 15 July 2017 and includes updates on measles, influenza A(H7N9), poliomyelitis, West Nile fever, rubella, salmonella and cyclosporiasis.

Since the notification of a novel reassortant influenza A(H7N9) virus on 31 March 2013, 1 548 laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus have been reported.

This rapid risk assessment builds on the fifth update of the ECDC rapid risk assessments on avian influenza published on 27 January 2017 [1] and on the recent public health development dated 24 February 2017.

Fifth update of the risk assessment on human infection with avian influenza A(H7N9) virus, summarising the epidemiological and virological information on the disease in China and Canada, and assessing the risk to public health in the EU/EEA.

This Rapid Risk Assessment summarises the epidemiological, virological and environmental information relating to outbreaks of highly pathogenic avian influenza A virus subtype A(H5N8) in Europe up to 15 November 2016.

This risk assessment looks at the risks of transmission in the EU/EEA and the options for response in connection with this localised outbreak.
