摘要
目的分析慈溪市1996-2011年肾综合征出血热(HFRS)的流行特征和发病规律,为预防、控制该病提供科学依据。方法对慈溪市1996-2011年HFRS人间疫情、鼠情、控制效果等进行定期监测,对监测资料进行分析。结果慈溪市16年间共报告HFRS515例,死亡2例,年平均发病率2.35/10万,病死率为0.39%。发病高峰在3-6月,呈单峰型。20～50岁青壮年人群高发,占病例总数的72.04%,职业分布以农民为主,占77.28%,男女性别之比为2.71∶1。室内外均以褐家鼠为优势鼠种,总带病毒率为5.32%。阳性鼠肺经PCR分型,均为汉城型汉坦病毒。结论慈溪市是家鼠型HFRS低中发病区,疫情呈逐年下降趋势;加强监测,做好灭鼠工作,是预防HFRS流行的有效方法。
Objective To analyze the epidemiologic characteristics of hemorrhagic fever with renal syndrome（HFRS） in Cixi city from 1996 to 2011, providing a scientific basis for the prevention and control of the disease. Methods Regular surveillance of the epidemic and rodent infestation in Cixi city from 1996 to 2011 was conducted and analysis on the data collected was made. Results In the 16 years, there were totally 515 cases of HFRS in the whole city and 2 cases of death with an annual incidence of 2.35/105 and mortality of 0.39%. This disease occurred around the year with peaks seen from March to June. People aged between 20 and 50 years were most often affected, accounting for 72.04% of the total cases. In terms of occupation, farmers were more often affected accounting for 77.28%. The ratio of male to female was 2.71 ： 1. Rattus norvegicus was the predominant species both outdoors and indoors, the virus-carrying rate being 5.32% （90/1692）. Positive rat lung were typed by PCR as Hanta virus. Conclusion There are epidemic foci with house-rat types in Cixi city, which belongs to a low to moderate incidence area with a trend of annual declining in the incidence of HFRS. Strengthening of surveillance and rodent control is an effective measure for the prevention of HFRS epidemic.
