H5N1 outbreaks in Nigeria, Ghana, Vietnam

Two H7N9 cases reported in China

Chinese officials have reported two H7N9 infections that occurred between September and Oct 10, but no details about the cases were available. The infections were noted in a government National Health and Family Planning Commission notifiable diseases overview in Chinese published on Oct 10 that was flagged, translated, and posted by FluTrackers, an infectious disease news message board.

FluTrackers said the cases are most likely two that were reported briefly by Chinese-language media reports in September from two cities in Zhejiang province, Jinhua and Huzhou. In addition, on Oct 4 FluTrackers flagged a foreign-language report of an H7N9 case in Shengzhou, another city in Zhejiang province.

The World Health Organization has said sporadic reports of H7N9 infections are expected in China, but global health officials are watching to see if the fall season will bring another wave. The second wave began in October 2013 with a small spurt of infections in Zhejiang province, and the fall of 2014 saw a start of a rise in H7N9 infections that carried into the winter months.

H5N1 killed 1,672 birds outright (14 in the backyard flock), and the rest were euthanized as a preventive measure.
