Spatial-temporal distribution characteristics of hemorrhagic fever with renal syndrome in Jingzhou, Hubei, 2005–2017

ObjectiveTo analyze the spatial and temporal distribution characteristics of hemorrhagic fever with renal syndrome (HFRS) in Jingzhou, Hubei province from 2005 to 2017 and provide reference for the development of HFRS prevention and control strategies.

MethodsThe incidence data of HFRS were collected from Infectious Disease Reporting Information System in China, and the annual statistical analysis was conducted by using the data from March to next February. Spatial autocorrelation analysis and space-time scan statistics were applied to analyze the incidence of HFRS in Jingzhou from March 2005 to February 2018 to describe the spatial and temporal clustering characteristics.

ResultsFrom 2005 to 2017, a total of 551 cases of HFRS were reported in Jingzhou. The annual incidence rate showed an increasing trend (r_s ＝0.901, P＜0.05). The incidence rate increased rapidly from 2016 to 2017. Spring and autumn-winter were the incidence peak seasons, and more than one subtypes of HFRS were detected in Jingzhou. The results of spatial and temporal scanning (upper limit of 15% population) showed that high incidence clustering areas were in the north of the Yangtze river from November 2011 to February 2018, including urban area of Shashi city, Jiangling and Jianli counties (29 streets and townships were involved). And 12 townships in Honghu city were added in the high risk clustering area list after December 2016.

ConclusionFrom 2005 to 2017, a new round of HFRS epidemic with increasing incidence occurred in Jingzhou, the key prevention and control areas were Jiangling, Shashi, Jianli and Honghu.
