Avian Influenza A (H7N9) Virus in a Wild Land Bird in Central China, Late 2015

In early 2013, the first case of a human infection with avian influenza A (H7N9) virus was reported in the Yangtze River Delta region of China (Liu et al. 2013). Since early 2013, a total of 1533 laboratory-confirmed human infections with avian H7N9 viruses have been reported to the World Health Organization (http://www.who.int/csr/don/28-june-2017-ah7n9-china/en/), with five epidemic waves of this virus occurring in China. Human infections with the highly pathogenic H7N9 influenza virus have emerged particularly in China (Zhang et al. 2017). The increasing numbers of human infections with H7N9 influenza viruses raises concerns that these viruses will continue to be a potential pandemic threat to public health.
It has been shown that the H7N9 virus responsible for the 2013 Chinese outbreak originated from gene reassortment among H7, N9 and H9N2 avian influenza viruses (AIVs), and it appears that the internal genes of the H7N9 viruses are most closely related to a wild land...
