More information on the source of the H7N9 bird flu virus has been unveiled by Chinese scientists. A recent research study done by the China Disease Prevention and Control Center is helping unravel the origins of the virus and how to contain its spread.

Poultry sold at markets and birds migrating through China are believed to be the sources of the H7N9 virus. Research showed that among 8 gene segments in H7N9, 6 are re-assorted ones from H9N2, which is another bird flu virus that is common among China's poultry. One gene segment is believed to have come from chickens in Jiangsu province, while the other 5 are believed to have come from chickens in Shanghai and areas surrounding Zhejiang province.
