Abstract

Abstract

Objective To analyze the prevalence and spatial clustering of severe fever with thrombocytopenia syndrome (SFTS) in Shandong Province from 2011 to 2020, and to provide the basis for SFTS prevention and control. Methods Case data were obtained from the Chinese Disease Control and Prevention Information System. The epidemiological characteristics and spatial aggregation of SFTS were analyzed by descriptive analysis, Joinpoint regression analysis, and spatial autocorrelation analysis. Results From 2011 to 2020, a total of 4 642 cases of SFTS were reported in Shandong Province, with an average annual incidence of 0.46/100 000 and 451 deaths, with an average case fatality rate of 9.72%. The peak of the disease occurs from May to September each year, and middle-aged and elderly farmers were the main population. JoinPoint regression analysis showed that the incidence of SFTS in Shandong Province had an increasing trend from 2011 to 2015, with an APC value of 38.93% (t=2.91, P=0.033), and tended to be stable from 2016 to 2020, with an APC value of 2.71% (t=0.53, P=0.620). Global spatial autocorrelation analysis showed that spatial aggregation existed in the incidence of SFTS from 2012 to 2020 (all P < 0.05) except for 2011 (Moran' I=0.011, P=0.168). Local spatial autocorrelation analysis showed that "high-high" clustering areas were mainly concentrated in the inland areas of central Shandong such as Jinan and Zibo, and the coastal areas of eastern Shandong such as Yantai and Weihai. Conclusions The incidence of SFTS in Shandong Province is seasonal and spatially clustered, so it is necessary to strengthen the monitoring and management of high incidence season and high-risk populations and intensify the prevention and control efforts in the inland and coastal areas of central and eastern Shandong Province.
