目的掌握浙江省肾综合征出血热(HFRS)流行特征,以制定有针对性的防治措施。方法采用描述流行病学方法分析疫情,实验室采用间接免疫荧光法检测HFRS患者血清中抗体,直接免疫荧光法检测鼠肺汉坦病毒抗原。结果2007年全省报告HFRS病例757例,主要分布在宁波、绍兴、台州、丽水、衢州等市,占全省发病总数的86.79%(657/757)。夏季和冬春季有2个发病高峰,青壮年农民病例居多。结论浙江省HFRS疫情近年呈平稳趋势,但一些县(市)发病率居高不下,应加强重点地区防制工作。
Objective To grasp the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Zhejiang Province so as to make targeted prevention and treatment measures. Methods Epidemiological methods were used to analyze the epidemic situation. Indirect immunofluorescence assay was used in the laboratory to detect the antibody in the serum of HFRS patients and the direct immunofluorescence assay was used to detect the Hantavirus antigen in mouse lung. Results In 2007, 757 HFRS cases were reported in the province, mainly in Ningbo, Shaoxing, Taizhou, Lishui and Quzhou cities, accounting for 86.79% (657/757) of the total number of cases in the province. There are two peak incidences in summer and winter and spring, with most young and middle-aged peasants. Conclusion The epidemic situation of HFRS in Zhejiang Province showed a steady trend in recent years. However, the incidence of HFRS in some counties (cities) remained high, and the prevention and control work in key areas should be strengthened.
