目的分析云南省肾综合征出血热流行病学特点,提供防治参考。方法收集全省HFRS疫情资料,进行统计分析。结果1976-2007年云南省共报告HFRS发病771例,死亡48例,年均发病率为0.06/10万,年均死亡率为0.0038/10万,病死率为6.23%。1985-1986年和2000-2004年出现两次流行高峰,近几年病死率明显下降。全省14个州、市的67个县(市、区)有病例报告。昆明、红河、楚雄和大理州(市)病例数占全省的84.21%,其中昆明市占全省发病数的40.17%。全年均有发病,春季为流行高峰。主要发病人群为男性青壮年农民。结论本病在云南省广泛分布,但主要流行地区为滇中和滇西地区,应加强高发地区的HFRS监测和防治工作。
Objective To analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome in Yunnan Province and provide reference for prevention and treatment. Methods The data of HFRS epidemic in the province were collected for statistical analysis. Results A total of 771 HFRS cases were reported in Yunnan Province from 1976 to 2007, with 48 deaths.
