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.
Influenza pandemics, whether mild, moderate or severe, affect a large proportion of the population and require a multisectoral response over several months or even years. For this reason, countries develop plans describing their strategies for responding to a pandemic supported by operational plans at national and subnational levels.

This meeting was designed to offer a place to exchange the latest information on into the development of narcolepsy following vaccination with one of the 2009 adjuvanted influenza A(H1N1) vaccines.

Australia has reported a cluster of oseltamivir-resistant influenza A(H1N1)2009 cases in the state of New South Wales. The cases had no known link to oseltamivir exposure and individuals were not immunosuppressed, but they were closely linked geographically. Samples from the cluster do not currently exhibit any resistance to zanamivir.
The 2010/11 seasonal influenza epidemics in Europe are dominated so far by the A(H1N1)2009 viruses which emerged in the 2009 pandemic, although these are now considered seasonal viruses. This is an interim risk assessment and will be up-dated at intervals as more data and analyses emerge.
