目的探讨临沂市2004—2012年肾综合征出血热(HRFS)流行规律,为制定相关预防控制措施提供科学依据。方法对临沂市2004—2012年HFRS疫情资料采用描述流行病学方法进行统计分析。结果临沂市2004—2012年共报告病例2 364例,年均发病率为2.54/10万;病死10例,病死率为0.42%。秋冬季、春夏季发病分别占总发病数的45.90%(1 085/2 364)和28.64%(277/2 364);发病以农民为主,占发病例数的87.35%(2 065/2 364);男女之比为2.64∶1;以20～50岁年龄组发病较多,占65.06%(1 538/2 364)。野外鼠密度为1.16%,以黑线姬鼠为优势种,占58.76%,带毒率1.94%;室内鼠密度为1.23%,以褐家鼠和小家鼠为优势种,占96.98%,带毒率2.12%。结论近年来临沂市HFRS发病率降低,但仍存在流行的潜在危险,应继续加强综合性的防治措施。
Objective To investigate the prevalence of hemorrhagic fever with renal syndrome (HFRS) in Linyi City from 2004 to 2012 and provide a scientific basis for making relevant prevention and control measures. Methods Epidemiological data of epidemic situation of HFRS from 2004 to 2012 in Linyi were used for statistical analysis. Results A total of 2 364 cases were reported in Linyi City from 2004 to 2012, with an average annual incidence of 2.54 / 100 000; 10 cases died and the case fatality rate was 0.42%. The incidence of autumn, winter, spring and summer respectively accounted for 45.90% (1 085/2 364) and 28.64% (277/2 364) of the total number of incidence. The incidence was mainly peasant, accounting for 87.35% (2 065/2 364) ). The ratio of male to female was 2.64: 1. The incidence was more in the age group of 20 to 50 years, accounting for 65.06% (1538/2364). In the wild, the density of rodents was 1.16%, the dominant species was Apodemus agrarius, accounting for 58.76% and the infecting rate was 1.94%. The indoor rat density was 1.23%. The dominant species were Rattus norvegicus and Mus musculus, accounting for 96.98% Toxic rate of 2.12%. Conclusion The incidence of HFRS in Linyi City has been reduced in recent years, but there is still a potential risk of epidemics. We should continue to strengthen the comprehensive prevention and treatment measures.
