摘要
目的 分析深圳市2008-2012年疟疾监测结果与疫情流行特点,为消除疟疾提供参考依据. 方法 整理深圳市2008-2012年“三热”病人血检监测及疟疾疫情报告资料,应用描述流行病学方法进行统计分析. 结果 2008-2012年全市血检监测“三热”病人93 048人次,平均年血检率为1.7‰.5年累计报告疟疾170例,平均年发病率为0.31/10万.其中间日疟128例,输入性恶性疟42例.本地病例数逐年下降,至2011年后未再有本地病例报告;输入性疟疾119例,占病例总数的70％.按地区分,报告病例数前三位依次是龙岗区（86例）、罗湖区（35例）和宝安区（28例）,其次为南山区（14例）和福田区（7例）.发病时间动态分布显示每年的6-10月为发病的高峰期.青壮年发病为主,20～39岁年龄段发病114例,占病例总数的67.1％.病例男女性别比为5.3∶ 1.往来非洲、东南亚等疟疾高发地区的农民工群体和商务人员为高危人群. 结论 近年来深圳市疟疾疫情相对稳定,但输入性恶性疟增加,应加强监测与防控.实施以输入性疟疾防治为重点的干预措施取得良好效果.
Objective To analyze the results of malaria surveillance and its epidemiological characteristics in Shenzhen during： 2008 to 2012 so as to provide evidence for the elimination of malaria. Methods We collected the data on malaria infection and surveillance of blood examination of patients with three fevers in Shenzhen City from 2008 to 2012, and then statistical analysis was conducted using descriptive epidemiological method. Results Blood examination was conducted in 93,048 febrile patients in Shenzhen from 2008 to 2012, with an average annual blood examination rate of 1.7%o. A cumulative total of 170 malaria cases were reported and the average annual incidence rate of malaria was 0.31/100,000. There were 128 cases of Plasmlium viva. infection and 42 cases of Plasmodium falciparum infection. Local infections declined gradually year by year and there were no local infections reported since 2011. 119 cases were imported, accounting for 70% of the total cases. There were 86, 35, 28, 14 and 7 cases reported in Longgang, Luohu, Baoan, Nanshan and Futian districts, respectively. The season distribution of malaria cases featured one peak period, which occurred during June- October. 67.1% （114/170） of the cases were in the age group of 20 - 39 years and the ratio of male to female was 5.3 1. Rural migrant workers and busine~,smen traveling to malaria- endemic regions, such as Africa and Southeast Asia, were populations at high risk of malaria infection. Conclusions The epidemic sit uation of malaria was relatively stable in Shenzhen in 2008 - 2012, but the cases of Plasmodium falciparum infection increased. Therefore, malaria- related surveillance, prevention and control work should be intensified. It is effective to implement preven- tion and treatment interventions focusing on imported malaria cases.
