Influenza is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent flu is by getting a flu vaccine each year.
A recently published study conducted between 2011 and 2018 in China, and based on surveillance data in pigs, identified an emerging genotype 4 (G4) reassortant Eurasian avian-like (EA) A(H1N1) swine influenza virus that contains internal genes from the human A(H1N1)pdm09 and North American triple-reassortant (TR) lineage-derived internal genes.
A pandemic is the rapid spread of a new human influenza around the world. Influenza pandemics happen when a new strain of a flu virus appears which can infect humans, to which most people have no immunity and which can transmit efficiently from human to human.
The joint annual influenza surveillance meeting by ECDC and the WHO Regional Office for Europe took place on 6 - 8 June 2018 in Copenhagen, Denmark. Invited participants were epidemiological and virological surveillance experts nominated by national health authorities as well as representatives from international institutions, covering the 53 countries of the EU/EEA and the WHO European region. The meeting was by invitation only.
No human cases of avian influenza were reported in the EU/EEA. Human cases of avian influenza A(H5N1) were reported from Egypt and A(H7N9) infections from mainland China, Hong Kong Special Administrative Region (SAR) and Taiwan.
Influenza vaccination coverage among high-risk groups has dropped in the European Region over the last seven years, and half the countries report a decrease in the number of vaccine doses available.
