Abstract：Objective To investigate the temporal and spatial distribution characteristics of A (H7N9) human infections in Hunan province from April 2013 to December 2018, and to provide scientific evidence for effective prevention and control of the epidemic. Methods The data regarding A (H7N9) human infections in Hunan province between April 2013 and December 2018 were collected from the China Information System for Disease Control and Prevention. And ArcGIS 10.2 software was used to analyze the temporal and spatial distribution trend and clustering of the cases. Results A total of 97 local cases of A (H7N9) human infections were reported in Hunan province between April 2013 and December 2018, which were distributed in 55 counties (districts) of 13 cities (prefectures). The incidence reached the peaks in winter and spring of 2013-2014 as well as 2016-2017, and no case was reported after September 2017. There were positive spatial autocorrelations in the distribution of the cases ofhuman infection withavian influenza A (H7N9) virus (Moran’s I=0.130, Z=2.240, P=0.025) during April 2013 and August 2017. Getis-Ord Gi statistics showed that thehotspots for case spatial distributions includedLinxiang city, Yueyang county and Yunxi district in northern Hunan, Xinshao county, Daxiang district, Shaoyang county, Xiangxiang city, Lianyuan city, Longhui county and Shaodong county in central Hunan, and Jiangyongcounty in southern Hunan (Z≥1.96). Conclusions Human infections with avian influenza A (H7N9) virus in Hunan province in 2013-2018 had obvious seasonal character, which reached the peaks in winter and spring.The cases were widely distributed, but weakly clustered spatially.
