Abstract
To better understand the role of wild birds in the emergence and potential dissemination of subtype H7N9 viruses, in late 2015, we collected samples from wild land birds in Hubei province and performed virus isolation as well as full genome sequencing. A novel H7N9 virus was isolated from a Magpie-Robin. Genetic analysis showed that the virus was highly similar to the H7N9 viruses that circulated in poultry in other provinces in 2014, suggesting that virus transmission might have occurred between these two regions. The presence of influenza viruses among magpie-robins could increase opportunities for spread to domestic farms and even to humans. This clearly makes it challenging to control the influenza H7N9 subtype. Therefore, it is important to continue monitoring avian influenza virus in wild land birds.
