目的了解浙江省湖州市2004-2010年疟疾疫情特征,为今后制订防治策略提供依据。方法用描述性流行病学方法对疫情资料进行统计分析。结果 2004-2010年确诊疟疾85例,年平均发病率为0.43/10万,各年发病率在1/10万以下,2007年发病率最高。疟疾病例主要集中在6-10月,主要分布在吴兴区、德清县和安吉县,发病人群构成以民工、农民和学生为主,中青年人群发病较多;病原学分型以间日疟为主,占94.67%(82/85),3例恶性疟均为外地输入;感染来源以输入性病例为多,占68.24%(58/85),输入性病例中,安徽籍病例占75.0%(42/56)。结论当前湖州市疟疾疫情处于较低水平,近几年发病呈明显下降趋势,且以输入性疟疾病例为主,因此在灭疟后期加强流动人口和劳务输出人口管理和监测,做好传染源控制和抗复发治疗,是防制疟疾的关键措施。
Objective To understand the characteristics of malaria in 2004-2010 in Huzhou City, Zhejiang Province, and to provide basis for future prevention and treatment strategies. Methods Descriptive epidemiological methods were used to analyze the epidemic data. Results 85 cases of malaria were diagnosed in 2004-2010, the average annual incidence rate was 0.43 / 100000, the annual incidence was less than 1/1000000, the highest incidence in 2007. Malaria cases are mainly concentrated in June-October, mainly in Wuxing District, Deqing County and Anji County, the incidence of the population to migrant workers, peasants and students, young people more; etiological classification mainly vivax malaria-based , Accounting for 94.67% (82/85). Three cases of falciparum malaria were imported. The number of imported cases was 68.24% (58/85). Among the imported cases, Anhui cases accounted for 75.0% (42 cases) / 56). Conclusions Currently, the epidemic situation of malaria in Huzhou City is at a low level. In recent years, the incidence of malaria has been on the decline. In the past few years, malaria cases with imported malaria are the main cause of malaria cases. Therefore, population management and monitoring should be strengthened in the later stage of malaria elimination, And anti-relapse therapy is the key measure to prevent malaria.
