Surveillance of syndrome of fever with thrombocytopenia and etiological detection in Beijing

Objective To evaluate the surveillance of syndrome of fever with thrombocytopenia or leucopenia and infection status of severe fever with thrombocytopenia syndrome virus（SFTSV） in Beijing.Methods The cases of fever（≥37.5 ℃） with thrombocytopenia（80×109/L） or leucopenia（3.0×109/L） were investigated with standard questionnaire and their blood samples were collected with non-anticoagulation tube and EDTA tube.RNA of SFTSV and DNA of Anaplasma phagocytophilum were detected by real-time RT-PCR and nested PCR respectively.Results During April-July in 2011,forty-five suspected cases of fever with thrombocytopenia or leucopenia were detected,including 27 in males and 18 in females aged 13-81 years.Two cases of SFTSV infection were laboratory-confirmed by real-time RT-PCR,which were from Henan and Anhui provinces,and 1 was fatal.No Anaplasma phagocytophilum were detected.ConclusionNo local SFTSV infection cases had been found through the surveillance system in Beijing.
