摘要
目的了解安丘市肾综合征出血热(HFRS)的流行规律及发病特征,为制定防控策略提供依据。方法应用描述流行病学方法分析安丘市1977~2017年HFRS发病趋势。结果 1977~2017年累计报告HFRS 3 529例,平均年发病率为8.57/10万,死亡74例,总病死率为2.10%。不同年份发病率差异有统计学意义(P<0.01)。1977~2017年安丘市HFRS经历了1985~1989、1997~2000年二次大的流行高峰(P<0.01)。发病秋冬峰(10~12月)稍高于春峰(3~5月)(P<0.01)。第1个流行周期(1977~1983年)、第2个流行周期(1984~1993年)、第4个流行周期(2003~2010年)、第5个流行周期(2011~2017年)秋冬峰发病明显高于春峰,而只有第3个流行周期(1994~2002年)春峰稍高于秋冬峰。发病数居前5位乡镇占全市发病总数的57.67%。男性发病率高于女性(P<0.01),性别比为2.67∶1;农民发病2 875例,占发病总数的81.47%。结论安丘市HFRS发病每10年左右为1个流行周期,每次流行高峰为2~6年;季节特征为双峰型,不同时期双峰分布呈不同特点。
Objective To understand the epidemiological rule and incidence characteristics of hemorrhagic fever with renal syndrome（HFRS）in Anqiu city,so as to provide scientific basis for effective strategies for prevention and control of HFRS. Methods The descriptive epidemiological method was conducted to analyze the incidence data of HFRS in Anqiu city from 1977 to 2017. Results During 1977 to 2017,there were a total of 3 529 HFRS cases reported,including 74 deaths（CFR 2.10%）in Anqiu city.The annual incidence was 8.57/105.The difference of incidence in different years was statistically significant（P〈0.01）.HFRS incidence in Anqiu had two big epidemic peaks,which were in 1985-1989 and1997-2000.The general incidence of HFRS fall-winter season（from Oct.to Dec）was a little higher than that of spring peak（from March to May）（P〈0.01）.Fall-winter season was significantly higher than that of spring season in the first epidemic phase（from 1977 to 1983）,the second phase（from 1984 to 1993）,the fourth phase（from 2003 to 2010）and the fifth（from 2011 to 2016）,but spring peak was a bit higher than that of fall-winter season only in the third phase（from1994 to 2002）The top five townships were accounting for 57.67%.The gender ratio in total was 2.67∶1.The number of HFRS patients in farmer,were 2 875,accounting for 81.30%. Conclusion There is a 10-year epidemic cycle in HFRS incidence in Anqiu city and each peak lasts 2-6 years;Seasonal characteristics is bimodal type and bimodal distribution with different characteristics in different periods.
