Phylogenetics of varied subtypes of avian influenza viruses in China: potential threat to humans

This is an excerpt from the content

Dear Editor,

Since February 2013, infections with several novel avian-origin influenza viruses have occurred in Taiwan and the Mainland of China. The H7N9 influenza virus has caused 136 human infections with 44 deaths in the first influenza season, and has continued to cause infections during the current influenza season (Li et al., 2014). As of February 11th, 2014, a total of 331 human infections with 101 deaths in China have been reported (http://www.nhfpc.gov.cn). During the outbreak of H7N9 in the Mainland of China, Taiwan reported the first human infection of avian H6N1 influenza virus, which again hit the public (Shi et al., 2013a; Wei et al., 2013). In November 2013, the first infection of H10N8 influenza virus was reported by Nanchang Center for Disease Control and Prevention (Chen et al., 2014). Questions have since been raised as to how many novel avian influenza viruses could emerge and infect humans, and which have the potential to cause a pandemic?

The three novel avian-orig
