Representatives from China, FAO, OIE and WHO agreed on a standardized terminology for the H7N9 influenza virus detected in China. For scientific reports, the term "avian influenza A(H7N9) virus" will be used, and can be modified to specify the type of infection, such as "human infection caused by the avian influenza A(H7N9) virus". For media like Twitter, shorter terms like "H7N9" or "H7N9 virus" can be used.
