Dear Editor,
H7N9 is a recently identified subtype of influenza A virus that caused a major outbreak in humans in China in 2013. According to the latest data provided by the Chinese Center for Disease Control and Prevention (http://www.moh.gov.cn/zwgk/yqbb3/ejlist.shtml, updated on October 31, 2018), the mortality rate of H7N9 infections in China amounts to 39.7% (611/1536). Thus, H7N9 poses a serious public health threat.
Influenza A viruses comprise a group of antigenically diverse pathogens that cause respiratory tract infections in both animal and human populations (Thornburg et al.2016). Subtypes of influenza A viruses are characterized by their surface glycoproteins, including hemagglutinin (HA) and neuraminidase (NA). HA consists of a globular head region with a receptor-binding pocket and a conserved stem motif (Liu et al.2016), and mediates the binding of influenza A virus to host cells (Melikyan et al.1999). After binding, HA can be divided into three domains: an…
