目的分析广西壮族自治区2000～2011年疟疾防治效果和流行动态,为调整疟疾防治对策和消除疟疾提供依据。方法收集2000～2011年疟疾疫情、疟疾调查资料和疟疾监测数据进行统计分析。结果2000～2011年广西检出疟疾患者2 406例,疟疾发病率从2000年0.91/10万下降至2011年0.21/10万。其中,2001～2008年发病率下降3.30%～43.75%,2009～2011年发病率上升11.11%～61.54%。监测12年,检出本地感染疟疾患者312例,占全自治区疟疾患者总人数12.97%(312/2406);检出输入性疟疾2 094例,占全自治区疟疾病例总人数87.03%(2094/2406)。结论广西本地感染疟疾流行已得到有效控制,输入性疟疾病例数增加是发病率上升的主要原因。加强输入性疟疾监测和管理,早期发现治疗传染源是控制输入性疟疾传播,巩固防治成果和实现消除疟疾目标的关键。
Objective To analyze the malaria control effect and epidemic dynamics in Guangxi Zhuang Autonomous Region from 2000 to 2011, and provide the basis for malaria control and malaria elimination. Methods The malaria epidemic from 2000 to 2011, malaria survey data and malaria surveillance data were collected for statistical analysis. Results A total of 2 406 cases of malaria were detected in Guangxi from 2000 to 2011, and the incidence of malaria dropped from 0.91 / 100 000 in 2000 to 0.21 / 100 000 in 2011. Among them, the incidence of 2001 to 2008 decreased by 3.30% to 43 .75%, the incidence of 2009 to 2011 increased by 11.11% to 61.54%. During the 12 years of surveillance, 312 cases of local malaria infection were detected, accounting for 12.97% (312/2406) of the total number of malaria patients in the autonomous region; 2 094 cases of imported malaria were detected, accounting for 87.03% of the total number of malaria cases in the autonomous region (2094/2406 ). Conclusion The prevalence of local malaria in Guangxi has been effectively controlled. The increase of imported malaria cases is the main reason for the rising incidence of malaria. Strengthening the monitoring and management of imported malaria and early detection of sources of transmission are key to controlling the spread of imported malaria, consolidating the results of prevention and treatment and achieving the goal of eliminating malaria.
