[目的]分析阜阳市2001～2007年疟疾疫情快速回升因素,为制定防治对策提供依据。[方法]收集阜阳市2001～2007年疟疾疫情资料、个案调查、媒介监测等数据进行流行病学分析。[结果]阜阳市2001～2007年共报告疟疾4 268例,年平均发病率6.76/10万,每年平均上升76.19%。其中58.11%的病例集中分布在颍上县,发病男女比例为1.6︰1,10～19岁年龄发病最多,占统计总数的23.12%,农民和学生是主要发病人群,分别占60.95%和24.65%。全年各季节均有发病,7～10月份为流行高峰季节,其间发病数占全年病例总数的74.51%。传播媒介为中华按蚊,蚊媒密度与疟疾发病率呈明显正相关关系(r=0.9175,P﹤0.01)。[结论]阜阳市疟疾疫情回升迅速,局部地区形势严峻。疟防措施落实不到位,传染源积累是疫情回升的主要原因。当地应加强疟疾防制措施并进一步落实,采取积极对策遏制疫情回升势头。
[Objective] To analyze the factors of rapid recovery of malaria in Fuyang City from 2001 to 2007, and provide basis for prevention and control measures. [Method] The data of epidemic situation of malaria from 2001 to 2007 in Fuyang City, case investigation and media monitoring were collected for epidemiological analysis. [Results] A total of 4 268 cases of malaria were reported in Fuyang City from 2001 to 2007, with an average annual incidence of 6.76 / 100 000, an average annual increase of 76.19%. Among them, 58.11% of cases were concentrated in Yingshang County, the incidence of male to female ratio was 1.6: 1, the incidence was the highest in 10 to 19 years old, accounting for 23.12% of the total, peasants and students were the main disease groups, accounting for 60.95% and 24.65% . The incidence of all seasons throughout the year, 7 to October for the peak season, during which the number of cases accounted for 74.51% of the total number of cases. The vector was Anopheles sinensis, and mosquito density was positively correlated with the incidence of malaria (r = 0.9175, P <0.01). [Conclusion] The epidemic situation of malaria in Fuyang City rebounded rapidly, and the situation in some areas was severe. Malaria prevention measures are not in place, the accumulation of sources of infection is the main reason for the rise of the epidemic. Local malaria prevention and control measures should be strengthened and further implemented to take positive measures to curb the upward trend of the epidemic.
