2009-2013年江西省宜春市肾综合症出血热流行病学研究

An epidemiological study on HFRS in Yichun City from 2009 to 2013

目的 对2009-2013年江西省宜春市肾综合症出血热（hemorrhagic fever with renal syndrome,HFRS）进行流行病学研究。方法 采用描述性与分析性流行病学方法描述分析2009-2013年宜春市HFRS的报告病例资料。结果 2008-2013年宜春市接种地区和非接种地区HFRS“16-60岁”年龄组报告发病数构成比均呈下降趋势,2009年之后“16-60岁”年龄组的HFRS报告发病率较为平稳,而非接种地区中呈明显上升态势。结论宜春市疫苗接种计划的实施很好地遏制住了HFRS疫情在“16-60岁”年龄组上升,但60岁以上人群发病率攀升,已逐渐成为了HFRS发病高危人群。

Objects To conduct an epidemiological study on the hemorrhagic fever with renal syndrome（HFRS） in Yichun City from 2009 to 2013. Methods The characteristics of HFRS reported cases between vaccination area and non-vaccination area on different age groups were described by epidemiological method and compared by statistical analysis. Results The constituent ratios of reported cases number in ＂16-60 year＂ age group were both decreasing in inoculation and non-inoculation areas from 2008 to 2013 and HFRS reported incidence of ＂ 16-60 year＂ group in the vaccination area was relatively stable after 2009, but was increasing in the non-vaccination area. Conclusions The implementation of HFRS vaccination program in Yichun City has curbed the increasing epidemic sit＇uation of the ＂ 16-60 age＂ group, but the incidence of over 60 age is increasing which have gradually became the highest HFRS risk group.
