Guangdong's Provincial Center for Disease Control and Disease reports that two virus samples collected from human hosts last month suggest that the H7N9 virus variants became more pathogenic in birds. 
Today Taiwan's CDC reports similar protein changes in the hemagglutinin (HA) protein that may make the virus more pathogenic in poultry.  
The WHO said the global total based on reports received since 2013 is 1,222 lab-confirmed cases םכ H7N9.
