Abstract:
We investigated the characteristics and epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) infection in Tiantai County,Zhejiang Province.Active surveillance and epidemiological investigation were employed with the serum samples collected simultaneously.The samples were detected by fluorescence quantitative PCR assay recommended by national standard of China.By descriptive epidemiology,the SFTS cases in 2012-2015 in Tiantai and related data were analyzed.In 2012-2015,there were 12 new cases of SFTS infection and 2 deaths,including 5 males and 7 females (39 to 75 yrs).The peak incidence was found from April to August.The main clinical manifestations was fever (100 ％),chills and fatigue (83％),and body pain (75％).The positive rate of nucleic acid screened in subclinical population was 1.4％;8 ca ses with definite records of tick bites (67 ％).In conclusion,several cases of SFTS have been confirmed in Tiantai County with two inapparent infections,which suggest the urgency and importance to strengthen the active surveillance,prevention and control measures and health education s in the coming days.
