Analysis of the results of malaria surveillance in Cixi, Zhejiang from 2001 to 2009

目的分析慈溪市2001-2009年疟疾流行特征,指导疟疾防治。方法用回顾性流行病学方法对慈溪市2001-2009年疟疾发病资料进行分析。结果 2001-2009年全市共检出135例疟疾病例,除1例为本地人口外出输入性感染,余均为外来人口输入性病例,外来流动人口疟疾平均年发病率2.17/10万;患者年龄主要为20～39岁,职业以民工为主;病原以间日疟为主,占99.26%。结论 9年来慈溪市在疟疾防治工作中取得了显著成绩,但由于流动人口带来的输入性病例时有发生,疟疾防治工作仍不可松懈。

Objective To get an insight into the current epidemiological characteristics of malaria in Cixi from 2001 to 2009 for the development of malaria control strategies. Methods Malaria surveillance data in Cixi from 2001 to 2009 were analyzed by retrospective epidemiological approaches. Results A total of 135 malaria cases were reported from 2001 to 2009 in the city. One of them was a local resident returning home with imported infection, while all of the others were imported cases. The annual average incidence of the floating population was 2.17/105. Most of them were the migrant workers at age 20-39 years and 99.26% cases were attributable to vivax malaria. Conclusion In the past 9 years, Cixi has made significant achievements in malaria control. However, in view of the occasional imported cases in the floating population, great importance should still be attached to malaria prevention and control in the city.
