目的对江苏省常州市7县(区)通过消除疟疾达标考核的评估结果进行分析,探讨适合本地区消除疟疾后的监测工作,为制订和调整消除疟疾策略和措施提供依据。方法收集2009-2014年常州市网络报告疟疾疫情、发热病人血检、专报系统中疟疾病例个案流行病学调查表、疫点调查和处置表等数据进行统计分析。现场对临床医生采用闭卷书面考试进行疟疾诊治知识考核;对检验人员进行疟原虫镜检技能考核;复核30张阴性血片。对当地最后1例疟疾病例所在自然村,采制不少于200人份居民滤纸血采样并进行疟原虫基因检测。结果 2009-2014年常州市共报告疟疾病例145例,血检发热病人170 638人次,检出阳性137例,阳性率0.08%;常州市除2009年和2010年分别有8例和2例本地感染疟疾病例外,其余均为输入性病例。7县(区)疟原虫镜检技能考核有4家单位平均分为20分,溧阳区平均分最低,为18.8分;疟疾诊治能力考核溧阳区平均分最高,为19.8分,戚墅堰区平均分最低,为18.0分;常州市7县(区)消除疟疾总考核得分均在93分以上。新北区、武进区、溧阳市和金坛市4个县(区)开展主动病例侦查,共检测731人份居民滤纸血采样,检测结果均为阴性。溧阳市于2012年,钟楼区和金坛市于2013年,天宁区、戚墅堰区、新北区和武进区于2014年通过消除疟疾县(区)级达标考核。结论常州市7县(区)均以高分通过消除疟疾达标考核,今后应继续做好消除后监测工作,巩固已取得的消除疟疾成果。
Objective To analyze the assessment results of malaria compliance assessment in 7 counties (districts) of Changzhou City, Jiangsu Province, and to explore the appropriate monitoring work after the elimination of malaria in this region and provide the basis for formulating and adjusting malaria elimination strategies and measures. Methods The data of epidemiological survey, epidemic investigation and disposal table of malaria cases collected from 2009-2014 online report of malaria epidemic, fever blood test and special report system in Changzhou city from 2009 to 2014 were collected for statistical analysis.
