Abstract: Objective To analyze intervals between illness onset and confirmation of severe fever with thrombocytopenia syndrome (SFTS) cases and related factors which will provide scientific information for its precise control and prevention. Methods Data on SFTS cases from 2011 to 2016 were obtained from China Information System for Diseases Control and Prevention. The intervals from illness onset to confirmation of SFTS cases in different genders, age groups, occupations, seasons, and provinces were summarized and compared using SPSS 20.0 software. Results A total of 5 360 SFTS cases were reported in China from 2011 to 2016 and the median interval from illness onset to confirmation of these cases was 9 d. Intervals from illness onset to confirmation of SFTS cases were significantly different from year to year and the maximum median of the interval of SFTS in 2014. Intervals between illness onset and confirmation of SFTS cases from different provinces were also significantly different, the intervals of Hubei province were the longest and the intervals of Zhejiang province were the shortest. Conclusion Although there were differences in the intervals of SFTS cases from different years, provinces and individual cases, the intervals were nevertheless very long. Appropriate interventions should be implemented to shorten the intervals for the control and prevention of SFTS.
