湖北省发热伴血小板减少综合征布尼亚病毒健康人群抗体水平分析

Analysis on antibody levels against severe fever with thrombocytopenia syndrome bunyavirus among healthy population in Hubei province

目的:调查评估我省人群中发热伴血小板减少综合征布尼亚病毒(SFTSV)抗体水平情况,为我省控制疫情提供流行病学线索。方法:抽取我省健康人群血清共957人份,采用ELISA法检测发热伴血小板减少综合征布尼亚病毒IgG抗体。结果:发热伴血小板减少综合征布尼亚病毒IgG抗体阳性率为6.37%,表明我省存在SFTSV的流行及隐形感染,调查的各地区之间人群抗体水平无显著性差异(χ2=11.59,P>0.01)。结论:湖北省是全国SFTSV的流行重点地区,需加强SFTSV的预防意识及快速诊断能力。

Objective：To evaluate the antibodies levels against severe fever with thrombocytopenia syndrome bunyavirus among healthy population in Hubei province and provide scientific evidence for prevention and control in our province.Methods： Nine hundred and fifty-seven healthy human serum samples were collected to detect the IgG antibody against SFTSV by ELISA.Results： The IgG antibody positive rate was 6.37%,warning the wide circulation and invisible infection of SFTSV in our province.There was no significant difference in the antibody levels of population among different areas（χ2=11.59,P0.01）.Conclusion： The Hubei province is the main popular area of SFTSV infection,so it is very necessary to strengthen the idea of prevention and the rapid ability of diagnosis.
