2013年湖北省麻城市发热伴血小板减少综合征布尼亚病毒人群感染状况调查

目的调查评估麻城市人群中发热伴血小板减少综合征布尼亚病毒(severe fever with thrombocytopenia syndrome bunyavirus,SFTSV)人群感染状况,为麻城市有效控制疫情提供流行病学线索。方法随机抽取麻城市3个乡镇健康人群血清共159人份,采用ELISA和Real time PCR检测发热伴血小板减少综合征布尼亚病毒IgG抗体、IgM抗体和特异性核酸。结果 SFTSV-IgG抗体阳性率为5.03%,SFTSV-IgM和SFTSV-PCR全部阴性。结论麻城市是湖北省SFTSV的流行重点县市,需加强SFTSV的预防意识及快速诊断能力。

Survey on the infectious status of population with severe fever with t~nia syndrome bunyavirus in Macheng City,Hubei Province in 2013

Objective To investigate and evaluate the infectious status of healthy population with severe fever with thrombocy- topenia syndrome bunyavirus （SFTSV） in Macheng City so as to provide scientific evidence for its effective prevention and control. Methods We randomly selected 159 serum samples from healthy population in three towns of Macheng City. Enzyme - linked immunosorbent assay （ELISA） and real- time polymerase chain reaction （PCR） were used to detect IgG and IgM anti- bodies to SFFSV and the specific nucleic acid. Results The seroprevalence rate of IgG antibody to SFTSV was 5.03 %, while SFTSV- IgM antibody and the specific nucleic acid were not detected. Conclusions Macheng City is the main endemic area of SFTSV infection in Hubei Province. It is necessary to enhance the awareness of SFTSV prevention and the ability of rapid diagnosis.
