H7N9

The influenza A(H7N9) virus is one subgroup among the larger group of H7 viruses that normally circulate among birds. A number of human infections of the H7N9 virus have been reported in eastern China, mostly in the Yangtze River Delta region since late March 2013. Some of the patients have died of severe pneumonia brought on by the virus. 

H7N9 harder to track but less likely to cause disease

While the spread of H5N1 has been halted by culls of chickens, this will not work with the H7N9 virus, as it is not known to have caused widespread deaths among birds or other animals, says Professor Yuen Kwok-yung, a microbiologist at the University of Hong Kong.
