目的分析广西地区2013年疟疾流行状况,为今后的疟疾防制方案的调整提供参考依据。方法收集全区各市县(区)全年疟疾疫情报告及疟疾个案调查资料,采用Excel 2003进行统计分析,确定全区疟疾病例的来源分布及各市发病率和感染的疟原虫种类等情况。结果 2013年广西共报告疟疾疫情1 251例,比2012年全年220例疟疾病例上升了468.64%;全年无内源性疟疾病例,报告的疟疾病例均为本地居民到非洲的16个国家及东南亚的4个国家感染后带回,其中96.88%(1 212/1 251)的病例为在非洲感染,恶性疟占88.24%(1 104/1 251)。疟疾病例分布在全区的49个县(市、区),6—7月的病例数占全年总数的68.91%(862/1 251)。3例疟疾危重病例经抢救后全部治愈。经积极防制后全区未发现继发性疟疾病例。结论 2013年全区由于从非洲务工人员短时期大量返乡导致当地疟疾病例急剧增加,并以恶性疟病例为主。
Objective To analyze the epidemic situation of malaria in Guangxi in 2013 and provide a reference for the future adjustment of malaria control programs. Methods The annual malaria epidemic situation reports and malaria cases survey data of all cities and counties (districts) in the whole district were collected. Statistical analysis was done by using Excel 2003 to determine the source distribution of malaria cases and the incidence of malaria cases and the types of infected malaria parasites in the whole area. Results In 2013, a total of 1 251 cases of malaria were reported in Guangxi, an increase of 468.64% over 220 cases of malaria in 2012. In the whole year, no cases of endogenous malaria were reported. The reported cases of malaria were both local residents and 16 countries in Africa and Four countries in Southeast Asia brought back the infection, of which 96.88% (1 212/1 251) were infected in Africa and the share of falciparum malaria was 88.24% (1 104/1 251). Malaria cases were distributed in 49 counties (cities and districts) in the region, accounting for 68.91% (862/1 251) of the total number of cases in June-July. Three cases of malaria were cured after the rescue. After the active control no secondary malaria cases were found in the whole area. Conclusion In 2013, the number of local malaria cases rapidly increased in the whole region due to a large number of returning migrant workers from Africa in a short period of time, mainly in the cases of falciparum malaria.
