目的分析1999~2013年玉林市疟疾监测结果及评价消除疟疾措施效果。方法对1999~2013年玉林的疟疾病例进行流行病学描述,并对该阶段疟疾监测方法和监测数据进行分析。结果监测1999~2013年玉林常住人口中的“三热”病人,共镜检血样169 501人份,均为阴性;检测本地居民血清抗体17 053人份,均为阴性。1999~2013年玉林共报告82例疟疾,均为输入性病例,其中,1999~2004年80.00%(12/15)为境内输入且均为间日疟,2005~2013年74.64%(50/67)为境外输入且有37.31%(25/67)的恶性疟。时间分布出现6月和11月两个高峰。职业分布中,建筑、采矿和种植等户外作业类职业占69.51%(57/82)。结论玉林市1999~2013年的疟疾防治措施有效,但仍存在疟疾病例输入风险,且风险来源由境内转移至境外。
Objective To analyze the results of malaria surveillance in Yulin City from 1999 to 2013 and evaluate the effectiveness of malaria elimination measures. Methods The epidemiological description of malaria cases in Yulin from 1999 to 2013 was conducted and the malaria surveillance methods and monitoring data were analyzed. Results A total of 169 501 blood samples were collected from all the residents of Yulin who were monitored during 1999-2013. All were negative, and 17 053 serum samples from local residents were negative. A total of 82 cases of malaria were reported in Yulin from 1999 to 2013, all of which were imported cases. Among them, 80.00% (12/15) were imported within the territory from 1999 to 2004 and both were Plasmodium vivax, 74.64% (50/67) ) Were imported overseas and had 37.31% (25/67) of P. falciparum. The distribution of time shows two peaks in June and November. Occupation distribution occupies 69.51% (57/82) occupations in outdoor operations such as construction, mining and planting. Conclusion The malaria control measures in Yulin City from 1999 to 2013 are effective, but there is still a risk of malaria cases being imported, and the sources of risks are transferred from outside to outside China.
