我市流行性出血热(EHF)首发于1970年,从1980年以来疫区逐年扩大,病例日益增多。截止1988年底全市已有16个区、县有病例报告,9年间共发生48例,死亡13例。平均年发病率为0.068/10万,病死率为27.1%。还对健康人群抗体水平进行了测定,阳性率仅为0.097%,证明本市人群抗体水平很低,存在着流行的可能,应引起高度重视。对宿主动物调查结果表明,褐家鼠是主要鼠种,占总捕获数的的40.12%,且带病毒率最高为3.56%,可以认为该鼠是我市 EHF 的主要传染源。作者建议在全市应加强灭鼠防病工作的宣传,防止流行性出血热的流行。
Epidemic haemorrhagic fever (EHF) in our city was first launched in 1970, and the epidemic area has been expanding year by year since 1980, with an increasing number of cases. By the end of 1988, 16 districts and counties had reported cases, with 48 cases occurring in 9 years and 13 deaths. The average annual incidence rate was 0.068 / 100,000 and the case fatality rate was 27.1%. Antibody levels were also measured in healthy population, the positive rate was only 0.097%, to prove that the population of the city’s low antibody levels, there is the possibility of epidemics, should be highly valued. The results of the investigation on host animals showed that Rattus norvegicus was the main mouse species, accounting for 40.12% of the total number of cats, and the highest virus-bearing rate was 3.56%. Therefore, it can be considered as the main source of EHF in our city. The author suggests that the city should strengthen the propaganda of anti-rodent prevention work to prevent the epidemic of epidemic hemorrhagic fever.
