Objective To analyze the epidemiological characteristics of fever with thrombocytopenia syndrome (SFTS) in Xinyang City from 2011 to 2015. Methods Descriptive epidemiological method was used to analyze the monitoring data of SFTS from 2011 to 2015 in Xinyang City. Using PHGIS1.7.0 software to draw SFTS case counties distribution, various rates of difference using the χ2 test. Results A total of 3 373 cases of SFTS were reported in Xinyang City from 2011 to 2015, with the incidence fluctuating between 7.22 / 100,000 and 19.80 / 100,000; 49 died and the case fatality rate was 1.45%. The cases were concentrated in Shangcheng County, Guangshan County and Bahe District, accounting for 70.29% of the total number of cases.

The incidence of females was 16.33 / lakh, higher than that of males (χ2 = 190.341, P <0.001). There were 3 241 cases of peasants, accounting for 96.09%. In 2011-2015, the positive rate of neburin in SFTS cases in Xinyang City was 61.09%, of which the highest was 68.07% in 60-99 years old.
