目的了解粤桂琼联防区广西8市县2009-2011年疟疾监测结果和流行特征,为调整疟疾监测和控制疟疾措施提供依据。方法收集8市县2009-2011年疟疾疫情资料和监测数据,分析评价疟疾流行和防治效果。结果 2009-2011年,8市县疟疾发病率分别为0.01/10万、0.04/10万和0.23/10万,2010年发病率比2009年上升300%,2011年发病率比2010年上升475%,发病率有逐年上升的趋势;常住人口发热患者血检40 379人次,未检出本地感染疟原虫阳性;流动人口发热患者血检19 992人,疟原虫阳性率0.08%。结论广西本地传播疟疾流行得到有效控制,流动人口输入疟疾导致发病率上升。落实流动人口疟疾监测和管理措施,防止输入性疟疾传播,才能巩固防治成果。
Objective To understand the malaria surveillance results and epidemiological characteristics of eight counties in Guangxi Zhuang Autonomous Region, Guangxi Zhuang Autonomous Region from 2009 to 2011, and provide the basis for adjusting malaria surveillance and malaria control measures. Methods The malaria epidemic data and surveillance data from 2009 to 2011 in 8 cities and counties were collected to analyze and evaluate the malaria epidemic and prevention and treatment effects. Results The incidence rates of malaria in cities and counties in 2009-2011 were respectively 0.01 / 100,000, 0.04 / 100,000 and 0.23 / 100,000. The incidence of malaria increased by 300% in 2010 compared with that in 2009 and the incidence of malaria in 2011 increased by 475% , The incidence rate has increased year by year; 40 379 blood tests of resident population febrile patients, no positive local infection Plasmodium; 19 992 blood samples of migrant febrile patients, the positive rate of Plasmodium 0.08%. Conclusion The prevalence of malaria transmitted locally in Guangxi has been effectively controlled. The incidence of malaria in floating population increased. To implement the malaria monitoring and management measures for floating population and prevent the spread of imported malaria in order to consolidate the results of prevention and treatment.
