General epidemic situation of hemorrhagic fever with renal syndrome in Zhejiang province in 2007

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 explore the epidemiological characteristics of hemorrhagic fever with renal syndrome（HFRS） in Zhejiang province for establishing pertinent prevention strategy. Methods Descriptive epidemiology method was applied for the analysis of epidemic situation. The antibody in the serum of HFRS patients was detected by indirect immunoflorscence method, and the HV antigen in the rodent lung was assayed by direct immunoflorseenee method. Results There were 757 eases in the whole province in 2007, mainly distributed in Ningbo, Shaoxing, Taizhou, Lishui and Quzhou, accounting for about 86.79% of the total （657/757）. There were two incidence peaks in summer, winter and spring. Most of the cases were young and middle-aged peasants. Conclusion The incidence rate of HFRS in Zhejiang province has been stable in recent years, but it was still high in some counties and cities. Therefore, the prevention and control of HFRS in the main epidemic areas should be strengthened.
