云南省消除疟疾行动计划项目进展

Progress of malaria elimination program in Yunnan Province

目的：分析云南省消除疟疾行动计划项目执行情况与疟疾流行和防治能力状况，为科学实施消除疟疾行动计划项目及考核验收工作提供参考依据。方法采用回顾性与现场调查相结合的方式，对云南省疟疾病例报告与处置、病原学检测、疟防能力状况等进行调查。结果2012年全省共报告疟疾636例，发病率为1.4/10万，发病率较比上年同期减少了46.7%。其中输入病例459例，占总病例数的72.2%；本地病例177例，占总病例数的27.8%；间日疟514例，占总病例数的80.8%；恶性疟120例，占总病例数的18.9%；三日疟2例，占总病例数的0.3%；死亡2例，占总病例数的0.3%。发病率在万分之一以下的一类县的比例和达到无本地感染病例的二类县比例较2011年分别提高了13.6%、25.0%，有一个三类县发生本地感染病例；一二类县和三类县在流行季节发热患者血检的比例相比2011年分别提高了15.6%、23.8%；病例规范治疗率和病例诊断后24 h 内病例报告率相比2011年分别提高了26.0%、16.3%；县疾病预防控制中心分管领导、疫情管理员和相关工作人员的项目管理、疟疾防治知识培训率和县级综合医院检验员的镜检培训率相比2011年分别提高了36.9%、32.1%，能开展疟原虫镜的州（市）、县（市、区）综合医院的比例和县（市、区）综合医院临床医生疟疾防治知识考核合格率较2011年分别提高了54.2%、22.2%。结论云南省基本实现了从控制阶段走向消除疟疾阶段的目标。

Objective To analyze the malaria control effect, situation and ability of malaria control by implemented malaria elimination project in Yunnan Province and provide reference for the scientific imple-mentation of the malaria elimination program and acceptance inspection work. Methods The data of malaria control including reported malaria cases, treatment of epidemic focus, malaria confirmed diagnosis cases and ability of control et al were surveyed by retrospective investigation and field survey. Results A total of 636 malaria cases were reported in Yunnan Province in 2012, the parasite incidence rate was 1.4 per 100 000, reduced by 46.7% compared to 2011, 72.2% of which were imported malaria and 27.8% were local malaria. 80.8% of the cases were vivax malaria, 18.9% were falciparum malaria, 0.3% were malaria malaria, and two cases died of malaria. Percentage of type I counties of parasite incidence rate below 1/10 000 and percentage of type II counties of reaching no local infection cases increased 13.6% and 25.0% respectively, compared to 2011. There was a type III county where local malaria was reported. The proportion of blood tests in patients with fever during the epidemic season in type I, II counties and type III counties increased 15.6%, 23.8%re-spectively, compared to that in 2011. The percentage of malaria patients who received regular treatment and cases reported within 24 h after diagnosis increased 26.0%and 16.3%respectively, compared to that in 2011. The percentage of training on project management, malaria prevention and treatment knowledge for project manager and leaders of Disease Control and Prevention of County increased 36.9%, compared to that in 2011;the percentage of training on microscopic examination for laboratory technician of County Hospital increased 32.1%, compared to that in 2011 The proportion of hospital with the ability to microscopically detect malariaparasites increased 54.2%, compared to that in 2011. The percentage of passing examination of malaria con-trol knowledge in hospital clinicians increased 22.2%, compared to that in 2011. Conclusion The goal of progressing from the stage of malaria control to the stage of malaria elimination has been basically achieved in Yunnan Province.
