Résumé :
|
Challenges in assessing and monitoring the influenza A(H1N1)pdm09 in 2009 highlighted shortcomings in global influenza surveillance, including the lack of a standardized approach to data collection. The 2013 Global Epidemiological Surveillance Standards for Influenza defined seven principal objectives of influenza surveillance, each of which is key to decision-making. This study assessed quantitative and qualitative information against these seven principal objectives to determine the performance of the European Region influenza surveillance network. The analysis showed that this network of national influenza experts in 50 countries of the World Health Organization (WHO) European Region, including the 28 European Union countries, contributes substantially to global influenza surveillance and health security. Through close collaboration among experts and standardization of surveillance across countries, the network provides timely information on the timing, spread and severity of seasonal influenza and acts as an early warning system for emerging respiratory viruses. Although substantial achievements have been made since 2008, some areas of influenza surveillance in Europe need to be further improved. Continued support of the network by participating countries, WHO, the European Centre for Disease Prevention and Control and other partners is an efficient way to build defence against the unpredictable nature of influenza viruses and other emerging respiratory pathogens such as Middle East respiratory syndrome coronavirus (MERSCoV). Such continued support will also ensure implementation of the core capacities required for surveillance and response under the International Health Regulations.
