Threat Assessment Brief: Eurasian avian-like A(H1N1) swine influenza viruses
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.
Rapid risk assessment: Oseltamivir-resistant influenza A(H1N1)2009 cluster in Australia
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.
ECDC Forward Look Risk Assessment: Seasonal influenza 2010–2011 in Europe
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.
