安吉县于1974年首次确诊流行性出血热(EHF)病人,嗣后常有发生,疫区逐渐扩大。为了解我县的EHF 流行规律,明确疫源地类型,我们于1989年对我县进行了流行病学调查。现将调查结果报告如下。资料来源搜集全县1974~1989年发病和流行资料。人群血清抗体测定从发病乡村采集既往病人、健康人群血清和无发病地区健康人群血清,采用反向间接血凝抑制试验(RPHIT)检测EHF 特异性抗体(IgG)。
Anji County, the first confirmed case of epidemic hemorrhagic fever (EHF) in 1974, subsequently occurred frequently and the epidemic area gradually expanded. In order to understand the epidemic law of EHF in our county and clarify the types of foci, we conducted epidemiological investigation in our county in 1989. The survey results are reported below. Sources of information collected throughout the county from 1974 to 1989 the incidence and prevalence data. Human Serum Antibody Assay EHF-specific antibodies (IgG) were detected by reverse-directed hemagglutination inhibition test (RPHIT) in sera from affected rural areas and from sera from healthy and non-endemic areas.
