目的分析环江毛南族自治县(简称环江县)2000—2014年疟疾控制后期疟疾发病特点,评价控制措施和防治效果,为调整疟防措施提供科学依据。方法收集2000—2014年环江县本地发热患者、疟疾病灶点居民、流动人口发热患者和非发热患者疟疾监测以及网络直报病例等资料,采用描述性流行病学方法对其进行描述和分析,流动人口发热患者与当地居民疟疾感染差异采用卡方检验。采用间接免疫荧光法(indirect immunofluorescence assay,IFA)检测居民疟疾血清抗体。结果 2000—2014年,环江县嗜人按蚊分布区共监测本地发热患者217 524人次,病灶点居民7 182人次,流动人口发热患者1701人次,流动人口非发热人群7730人次,4类人群疟原虫阳性率依次为0.02%(38/217 524)、0.03%(2/7 182)、1.71%(29/1 701)和0(0/7730)。共检出疟疾患者69例,其中本地感染病例占57.97%(40/69),流动人口输入性病例占42.03%(29/69)。2000—2014年共捕获蚊虫43 387只,其中中华按蚊占98.06%(42 545/43 387);嗜人按蚊占0,89%(282/43 387),2010—2014年未发现嗜人按蚊。重点人群IFA抗体阳性率仅为0.13%(2/1488)。结论 2006年起,环江县未检出本地传播病例和输入继发病例,疟疾发病以境外输入性病例为主,为如期实现广西消除疟疾目标,应加强对外出非洲和东南亚地区务工返回人员疟疾管理和监测,及时发现和有效治疗输入性传染源。
Objective To analyze the characteristics of malaria in late malaria control from 2000 to 2014 in Huanjiang Maonan Autonomous County (Huanjiang County), evaluate the control measures and prevention and treatment results, and provide a scientific basis for malaria prevention and control measures. Methods The data of local malaria patients, residents with malaria focal point, migrant fever patients and non-febrile patients with malaria and network direct reports from 2000 to 2014 were collected and described by descriptive epidemiological methods. Migratory febrile patients and local residents malaria infection using chi-square test. Indirect immunofluorescence assay (IFA) was used to detect malaria serum antibody. Results From 2000 to 2014, 217 524 local fever patients, 7 182 residents with focal point, 1701 migrant fever patients, 7730 non-fever floating population and 4 malaria-positive malaria patients were monitored in the distribution area of Anopheles anthropophagus in Huanjiang County. The positive rates of protozoa were 0.02% (38/217 524), 0.03% (2/7 182), 1.71% (29/1701) and 0 (0/7730) respectively. A total of 69 malaria cases were detected, of which 57.97% (40/69) were local cases and 42.03% (29/69 cases) were migratory cases. A total of 43 387 mosquitoes were captured between 2000 and 2014, of which Anopheles sinensis accounted for 98.06% (42 545/43 387), Anopheles anthropophagus accounted for 0,89% (282/43 387) and no anger was found between 2010 and 2014 Anopheles. IFA antibody positive rate of the key population was only 0.13% (2/1488). Conclusions Since 2006, no local transmission cases and no secondary cases have been detected in Huanjiang County. The incidence of malaria is mainly imported outside China. In order to achieve the goal of eliminating malaria in Guangxi on schedule, malaria should be strengthened in returning workers from Africa and Southeast Asia Management and monitoring, timely detection and effective treatment of imported sources of sexually transmitted infections.
