目的评价“嗜人按蚊分布区疟疾综合防治对策”研究成果在疟疾回升或爆发点现场的应用效果,为该类疟区今后防治工作提供依据。方法用回顾性调查方法,对盐津、彝良、永善三县2003～2006年期间疟疾点状爆发和回升地区的现场防控资料,进行流行病学整理和分析。结果盐津、彝良和永善3县2005～2007年疟疾发病占全市11县的92.65%。发生于盐津县豆沙镇石门村和彝良县牛街镇花果村的疟疾点状爆发及大幅回升,属历史高疟区的当地病例传播引起;发生于彝良县钟鸣乡麻窝村和永善县码口乡烟坪村的疟疾病例,属于历史无疟区的输入性突发疫情。通过应用嗜人按蚊区疟疾发病率>10/万地区的防治对策,及时控制疟疾的爆发、回升及输入性疫情。各村点次年疟疾发病率下降55.56%～100%;输入性疟疾病例及时治愈,没有发生二代病例,次年亦未发生疫情。结论认真执行分类指导、分层防治疟疾的原则,就能有效的控制云南嗜人按蚊分布区的疟疾流行。
Objective To evaluate the application results of malaria countermeasures in the distribution area of the Anopheles anthropophagus in the field of malaria recovery or outbreak and provide the basis for the future prevention and control work of this kind of malaria area. Methods A retrospective survey was conducted to analyze and control the epidemic prevention and control data of the spot-breaking and recovery areas of malaria from 2003 to 2006 in Yanjin, Yiliang and Yongshan counties. Results The incidence of malaria in Yanjin, Yiliang and Yongshan 3 counties from 2005 to 2007 accounted for 92.65% of the 11 counties in the city. Occurred in Shijin Village, Dousha Town, Yanjin County and the spotty outbreak of malaria and the substantial recovery from malaria in Huaguo Village, Niujie Town, Yi County, were caused by local cases of transmission in the historical high malaria area; occurred in Mawo Village, Zhongming Township, Yi County The case of malaria in Yanting Village, Juekou Township, Yongshan County belongs to the imported sudden epidemic outbreak in history. The outbreak, recovery and imported epidemic of malaria should be promptly controlled through the application of prevention and treatment measures for malaria incidence in an anopheles zone with an area of> 10 / 10,000 areas. In the following years, the incidence of malaria dropped by 55.56% to 100% in each village. The cases of imported malaria were cured in time and the second-generation cases did not occur. No epidemic occurred in the following year. Conclusion The implementation of the guidance of classification and the principle of stratified malaria control can effectively control the malaria epidemic in the distribution area of Anopheles anthropophagus.
