An epidemic of human infection (h-H7N9 AI)
with a novel Avian Influenza A (H7N9) virus (h-H7N9 AIV)broke out in China in
2013. The first case occurred in Shanghai on February 19, 2013, neighbouring
provinces were involved in the next months. Until May 10, 2013, 131 confirmed
cases had been reported to the World Health Organization (WHO), of which 32cases died (24.4%).
It was considered that the incidence and mortality were both
high. Six hundred and twenty eight cases were confirmed up to April, 2015.
Until June 2016, 767 cases had occurred only in the mainland with inputting

China, therefore, it cannot be spread outward. “Natural Focus Disease” often is
referred to as “Zoonosis” by most scholars in scientific papers. Read more>>>>>>>>>>>>>>
