摘要:

目的 分析河北省2011年肾综合征出血热(HFRS)流行特征,对监测数据进行综合分析,为制定防制对策提供科学依据。方法 收集全省HFRS疫情资料,对各监测点鼠密度和鼠带病毒率进行监测,对阳性鼠肺进行基因分型。结果 2011年全省共报告HFRS病例513例,死亡1例,发病率为0.71/10万,病死率为0.20%。病例分布于全省74个县(市、区),主要集中在秦皇岛和唐山市;具有明显的春季及冬季流行高峰,3-6月占发病总数的42.50%,10-12月占30.02%;发病以青壮年为主,20~59岁组发病364例,占病例总数的70.96%;男女之比为2.72:1;农民发病占78.36%。居民区鼠密度为2.04%,带病毒率为7.41%;野外鼠密度为0.64%,带病毒率为0。居民区和野外优势鼠种均为褐家鼠;阳性鼠肺进行PCR分型,结果均为家鼠型(Ⅱ型)。结论 河北省是以家鼠型为主的混合型疫区,应以高发病较集中的9个县(区)为重点,加强HFRS综合防治。

Abstract:

Objective To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Hebei province, China in 2011 and analyze the surveillance data and to provide a scientific basis for the control of HFRS. Methods The epidemic data of HFRS were collected. The density and virus-carrying rate of rodents at each surveillance site was recorded. PCR genotyping was performed using the positive lungs of rodents. Results In 2011, 513 cases of HFRS including one death were reported in Hebei province, with an incidence rate of 0.71/105 and a fatality rate of 0.20%. These cases were distributed in 74 counties (cities, districts), mostly in Qinhuangdao city and Tangshan city, in Hebei. The peak seasons were in spring and winter. The percentage of cases occurring from March to June was 42.50%, and 205 cases (30.02%) occurred from October to January of the next year. Of all cases, 364 (70.96%) were aged 20-59 years. The male-to-female ratio was 2.72:1. Peasants amounted for 78.36% of all cases. The rodent density in residential area was 2.04%, and the virus-carrying rate was 7.41%; the rodent density in the field was 0.64%, and the virus-carrying rate was 0. The dominant species of rodents in the residential area and field was Rattus norvegicus. The PCR genotyping using positive lungs showed that all belonged to Rattus type (type Ⅱ). Conclusion Hebei province is a mixed epidemic area of HFRS, mostly of Rattus type. We should enhance comprehensive control of HFRS with an emphasis in the 9 counties (districts) with high incidence of HFRS.
