从1983年1月19日广州市海珠区出现首例经血清学证实的流行性出血热(EHF)病例以来,同年8月,在海珠区和郊区捕获的褐家鼠鼠肺用间接免疫萤光法(IFA)检查出EHF抗原,首次证实广州为EHF疫源地,至1984年11月为止,共发生了血清学证实的病人24例(其中死亡3例)。为了对全市人间与鼠间EHF流行情况进一步了解,我们两年来对本市鼠种带毒率与抗体率、人群抗体水平作了调查。现将结果报告于下。
Since January 19, 1983, the first case of serologically confirmed epidemic hemorrhagic fever (EHF) was reported in Haizhu District of Guangzhou City, in August of the same year, the Rattus norvegicus capitatum captured in Haizhu District and the suburbs was infected with indirect immunofluorescence (IFA) detected EHF antigen, Guangzhou was the first confirmed EHF epidemic, as of November 1984, a total of 24 cases of serological confirmed patients (including 3 deaths).
