目的分析2008~2013年桂林市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,为确保广西2018年消除疟疾目标的实现提供科学依据。方法收集2008~2013年桂林市输入性疟疾病例个案调查表、网络直报病例等监测数据,对输入性疟疾的感染来源、虫种、人群和地区分布等进行描述和统计分析。结果 6年来,全市共报告境外和区外输入性疟疾病例72例,其中恶性疟40例,间日疟29例,三日疟2例,混合感染1例,死亡2例。病例主要分布在全州、恭城、桂林市区、兴安、灵川、资源和永福等。男女性别比为13.4:1,年龄分布集中在20~50岁组。境外输入病例最多的是非洲加纳36例,其次为柬埔寨10例,再次为缅甸8例。结论当前桂林市疟疾发病以境外输入性病例为主,且多数为恶性疟。为确保2018年广西消除疟疾目标的实现,应加强对外出非洲和东南亚地区务工返回人员的疟疾监测,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 in Guilin from 2008 to 2013 and to provide a scientific basis for further monitoring and diagnosis and treatment of malaria in late malaria control in order to ensure the elimination of malaria in Guangxi in 2018. Methods The data of case malaria cases and direct cases of direct malaria cases in Guilin city collected from 2008 to 2013 were collected to describe and statistically analyze the source, worm species, population and geographical distribution of imported malaria. Results In the past 6 years, 72 cases of imported malaria were reported in the city, including 40 cases of Plasmodium falciparum, 29 cases of Plasmodium vivax, 2 cases of Plasmodium malaria, 1 case of mixed infection and 2 cases of death. Cases are mainly distributed in Jeonju, Gongcheng, Guilin, Xing’an, Lingchuan, Yongfu resources and so on. The male-female ratio was 13.4: 1, and the age distribution was concentrated in the 20-50 age group. The largest number of imported cases were Ghana in Africa 36 cases, followed by Cambodia 10 cases and again Myanmar 8 cases. Conclusion The incidence of malaria in Guilin City is mainly imported outside the country, and the majority is falciparum malaria. In order to ensure the achievement of the goal of malaria elimination in Guangxi in 2018, malaria surveillance should be strengthened for those returning from work in Africa and Southeast Asia to promptly detect and effectively treat imported sources of transmission.
