Global concern regarding the fifth epidemic of human infection with avian influenza A (H7N9) virus in China.
Shen Y, Lu H
Since the first outbreak of human infection with avian influenza A (H7N9) virus was identified in 2013, five seasonal outbreaks have occurred in China. The fifth outbreak started earlier than usual. A sudden increase in cases of human infection with avian influenza A (H7N9) virus has been reported in China since September 2016, and the number of cases reported in this season is exceeding that reported in previous seasons. This increase in the number of new cases of H7N9 infection has caused domestic and international concern. This paper summarizes the current prevalence of H7N9 in China and it also discusses measures that China has taken to control this outbreak. This paper also describes steps China must take in the future. This paper can serve as a reference for prevention and control of H7N9 outbreaks around the world.
