A H79N outbreak is estimated to have cost Chinese poultry producers over 13 billion yuan. (1.6 billion euro)
As it stands 77 human cases have been confirmed in the country and 16 people have died according to worldpoultry.net
Chinese authorities have undertaken measures to contain the spread of the virus by destroying poultry in large numbers as well as closing poultry markets in Shanghai and Beijing.
Approximately 47,800 samples have been tested from 84,444 samples collected in both national and provincial labs.
All of the 39 positive samples which were taken from live poultry have been traced back to Shanghai and the Anhui, Zhejiang and Jiangsu provinces, all of which confirmed cases of H7N9 bird flu.
The H79N virus has dramatically reduced consumer confidence which is reflected in a sharp fall in the prices of poultry and eggs.
