目的分析田东县基本消灭疟疾达标后输入性疟疾流行病学特点和趋势,为进一步提高疟疾控制后期输入性疟疾监测及诊治能力,保证2018年消除疟疾目标的实现提供科学依据。方法收集1998~2013年田东县输入性疟疾病例个案调查表、网络直报病例以及流动人群疟疾监测等数据,对输入性疟疾的感染来源、虫种、人群、时间及年龄分布等进行描述和统计分析。结果 16年来,田东县共监测外出务工返回人员5 768人次,检出输入性疟疾15例,包含恶性疟4例,间日疟11例,原虫阳性率为0.26%,其中1998~2000年8例,2001~2005年7例,2006年起未检出输入性疟疾病例。男性14例,女性1例;年龄分布集中在17~55岁。结论田东县1997年基本消灭疟疾考核达标以来,不再出现本地感染病例,疟疾发病以输入性病例为主,应加强对外出非洲和东南亚地区务工返回人员疟疾监测,及时发现和有效治疗输入性传染源。
Objective To analyze the epidemiological characteristics and trends of malaria imported from malaria in Tiandong County after malaria elimination and to provide a scientific basis for further improving the monitoring and diagnosis and treatment of malaria in the later stage of malaria control and ensuring the elimination of malaria in 2018. Methods The data of malaria cases of imported malaria in Tiandong County from 1998 to 2013, network direct reports and surveillance of malaria in mobile population were collected to describe the origin, worm species, population, time and age distribution of imported malaria Statistical Analysis. Results Tatandong County monitored a total of 5 768 returned migrant workers over the past 16 years. 15 cases of imported malaria were detected, including 4 cases of Plasmodium falciparum, 11 cases of Plasmodium vivax and 0.26% of protozoa, of which 8 For example, from 2001 to 2005, seven cases of imported malaria were not detected in 2006.

Conclusion Since the elimination of malaria in Tiandong County in 1997, the incidence of local malaria was no longer seen. The incidence of malaria was mainly based on imported cases. Malaria surveillance should be strengthened for returnees who came out of Africa and Southeast Asia, and timely detection and effective treatment of imported Source of infection.
