目的分析高安市疟疾流行与防治历程,评估高安市消除疟疾工作,为今后和其他地区的疟疾消除工作提供科学依据。方法对高安市1950—2015年疟疾疫情数据、防治策略和措施进行回顾性分析;2010年启动消除疟疾行动计划后,依据国家卫生计生委《消除疟疾考核评估方案(2014版)》要求,对消除措施进行综合评价。结果高安市1969年疟疾年发病率高达440.94/万,经过几代疟防人员的不懈努力,2000年年发病率下降至0.038/万,达到了基本消灭疟疾标准。随后的工作重点转为对重点人群监测,2010年启动消除疟疾行动计划至今共报告5例疟疾病例,均为输入性病例,全市29个镜检点累计血检不明原因发热病人6 851人次,血检率大于总人口0.5‰的标准,复核血片695张,复核率10.15%,共检出4例阳性病人。经疫点处置,未出现二代病例。媒介监测结果表明,高安市传疟媒介主要为中华按蚊,6—10月监测平均密度为14只/h。结论高安市自2005年报告最后一例本地感染疟疾病例后,已连续10年无本地感染病例报告,达到了消除疟疾标准。
Objective To analyze the malaria epidemic and its prevention and cure in Gao’an, assess the malaria elimination work in Gao’an and provide a scientific basis for malaria elimination in the future and in other areas. Methods The malaria epidemic data, preventive and control strategies and measures in 1950-2015 in Gaoan were retrospectively analyzed. After the malaria elimination program was launched in 2010, according to the requirements of the National Health and Family Planning Commission’s “Elimination of Malaria Assessment and Assessment Program (2014 Version)”, Comprehensive evaluation of measures. Results The incidence of malaria in Gao’an City in 1969 was as high as 440.94 / million. After several generations of malaria prevention staff’s unremitting efforts, the annual incidence rate in 2000 dropped to 0.038 / million, reaching the standard of malaria elimination basically. Subsequent work shifted to monitoring of key populations. Since the Malaria Elimination Malaria Action Plan was launched in 2010, a total of 5 cases of malaria were reported, all of which were imported cases. There were 6 851 persons with blood tests of unknown causes Inspection rate is greater than the total population of 0.5 ‰ standard, 695 check blood film, review rate of 10.15%, a total of 4 positive patients were detected. Disposal by the epidemic, there is no second-generation cases. The results of media monitoring showed that the mass malaria transmission vectors in Gao’an were mainly Anopheles sinensis, and the average monitoring density in June-October was 14 / h. Conclusion Since Gao’an City reported the last case of local malaria infection in 2005, it has reported no case of local infection for 10 consecutive years and met the malaria elimination standard.
