Influenza A(H7N9) virus, or 'H7N9', has had a quiet year when compared to past outbreaks.
All human cases to date have been linked to China. The majority of human cases have had some link with poultry - chickens or ducks - although we do hear of human-to-human transmission, this seems to be limited. H7N9 has been found in poultry from backyard farms and in live poultry markets (LPMs) in China - sometimes in the company of other influenza viruses, like H9N2.

Time, and testing data - which China generates lots of but does not seem to enjoy publicly reporting - will tell.
In 2016 - 2 new regions were added for the first time - Tianjin municipality and Liaoning province - both in the north-eastern coastal region of China.
In 2013, no sustained human-to-human transmission had been reported  - this remains true up until today.
